Holy Toledo! It’s been a loooong time since my last post! I knew it had been awhile but when I did the math it’s officially been 24 days – that’s over three weeks! Definitely a record since I created this space almost four years ago!
So much has changed since then, it’s almost staggering to think about! Hungry Jr. will be eight this summer, we’ve relocated back to the Northeast, and this blog and related projects have become my full time job – not to mention a million other small things. It’s been a lot of hard work, but we’re having a blast!
Also I have to say that in spite of the fact that it’s freezing here and I’m literally looking through my window at guys ice fishing on the frozen lake, it’s STILL good to be back in the Northeast – even if I never imagined I’d be referring to myself as a New Yorker! That’s pronounced New Yaw-kah to you non Yankee folks btw.
We still have a lot of loose ends to tie up (unpacking, registering vehicles, changing licenses, etc.) but this already feels like home. Since we couldn’t quite fit everything in the moving truck on the way up last week, we’re heading to SC next week to get the rest of it. Then we’ll be back here for good the week of the sixth, and I’ll finally be able to get back in the groove of regular posting – which I’m super excited about because I’ve got a LOT of great new recipes to share with you guys!
But enough about my travel schedule, let’s talk lemon bars! One of my absolute favorite desserts, it’s the thing I’m most likely to gaze longingly at through the glass at a bakery or coffee house – and sometimes I give in and have one. I’m never really sorry until the next day when I wake up puffy and bloated from the gluten and sugar. Even then it’s usually worth it if I’m being honest.
I finally decided though that it was high time I came up with a keto friendly lemon bar recipe that would meet my low carb and gluten free criteria (and save me from the morning after bloating.) As an added bonus these are pretty easy to make, and just as good or better than the “real” thing. I’m not just saying that either, I tested these out on crowds of non low carbers at several parties – all with rave reviews and no leftovers.
This low carb lemon bar recipe is basically the love child of my Lemon Almond Shortbread Cookies (crust), and my Sugar Free Lemon Curd (filling) recipes, with a few minor tweaks.
I like my lemon bars a little on the tart side, but you can increase the sugar free sweetener in the curd if you prefer them sweeter – or you can add more powdered sugar free sweetener to the top of them after baking.
I’m confident that you guys are going to love these low carb lemon bars – they simply scream “IT’S SPRING BABY!” and they’ll make you believe it – even if the view from your kitchen window is as cold and unspringlike as mine right now. :/
Can’t wait to hear what you think! Make them and report back STAT! Meanwhile, look for more delicious low carb and gluten free recipes coming to IBIH soon!!!!

Pin RecipeDescription
A tasty Keto lemon bar recipe that’s just as good or better than the classic lemon bar – but low carb and gluten free!
Ingredients
For the Crust:
- 6 tablespoons butter
- 2 cups superfine blanched almond flour
- 1/3 cup granulated sugar substitute (I used Swerve)
- 1 tablespoon freshly grated lemon zest
For the Filling:
- 1/2 cup butter
- 1/2 cup granulated sugar substitute (I used Swerve)
- 1/2 cup fresh lemon juice
- 1/4 cup grated lemon zest
- 6 egg yolks
- 1/2 teaspoon xanthan gum
- 2 tablespoons unflavored collagen powder (or 1 teaspoon unflavored gelatin)
Instructions
For the crust:
- Preheat the oven to 350 degrees.
- Melt the butter in the microwave or a small saucepan.
- Add the almond flour, sweetener, and lemon zest, stirring until fully combined.
- Press the dough evenly along the bottom and 1/2 inch up the sides of an 8 x 8 inch square pan. For best results line the pan with parchment paper or foil first, then you can simply lift out the completed lemon bars.
- Bake for 10 minutes.
- Remove and cool while you make the filling.
For the filling:
- Melt the butter in a small saucepan on low heat.
- Remove from heat and whisk in sweetener, lemon juice, and lemon zest until dissolved.
- Whisk in the egg yolks and return to the stove over low heat.
- Whisk continually until the curd starts to thicken.
- Remove from the heat and strain into a small bowl.
- Whisk in the the xanthan gum and collagen or gelatin until dissolved and smooth.
- Pour the filling over the pre-baked crust and spread out evenly to the edges of the pan.
- Bake the bars at 350 degrees (F) for 15 minutes.
- Remove and cool.
- Sprinkle with Powdered Swerve before serving if desired.
- Cut into sixteen 2 x 2 squares.

June 19, 2019 at 2:38 amSo many of your recipes are great, and this one is no exception. But, that one glaring error is still in the ingredients, and I, like many others over the years, followed the recipe as written without reading 10 minutes worth of comments, was blissfully unaware of the wording mistake in the recipe. Gelatin comes in powder and sheet form, Knox brand being the most available and well-known in Canada and the U.S. Apparently, what you are using in the recipe is not gelatin at all, but collagen powder, which also gels. Can you please change the ingredients to specify collagen, as opposed to true gelatin? I would hate to see any more people misled by this honest mistake and ending up with a yummy square of rubbery Jello.
Mellissa Sevigny says
June 20, 2019 at 11:17 amThanks for the reminder Mina, this recipe should have been updated years ago!
Inez says
June 9, 2019 at 10:18 pmI have never used 1/4 CUP of zest in anything. Is this correct? I only get a couple tsp from a large lemon.
Mellissa Sevigny says
June 10, 2019 at 8:14 amIt depends on how fine you’re grating it. If it’s really fine and packed down then 1 tablespoon will do it, but if you’re using larger shreds you’ll need the 1/4 cup. The more lemon zest, the more intense the lemon flavor.
Ellen says
April 24, 2019 at 4:51 pmHi there, I made the recipe above, did it because everyone likes lemon. So it was my Easter dessert. The only comment people said they thought it was too much lemon. for both the crust and the insides, I feel it took about two large lemons. I will definitely make again, but just use less lemon. Just wondering though why do we drain the zest out, thought it might be nice to be in the filling? everyone loved the crust also by the way. It is 4 days after easter and crust is holding up great, it is in the fridg in tupperware. Just wanted to share it.
Laura says
April 9, 2019 at 3:36 pmMy filling came out liquid-y…. 😩. Failed on my part. Any suggestions? I noticed my filling wasn’t getting thick when I added the yolks..
Zandra says
January 29, 2019 at 10:54 pmI am new to keto and I have been struggling with the lack of sugar. Confession: I was addicted before I started. lol This recipe is everything I want and needed. I don’t normally comment on these things either, but I must so than anyone who loves lemon and wants a satisfying recipe, this is it. Hands down.

Dyana says
January 6, 2019 at 8:15 pmYUMMMM!!! Made these tonight & they are delicious!!! I used the boxed plain gelatin, and after reading a comment about them turning out rubbery, I used only 1 Tbsp instead of 2~turned out perfect!!!!

Brittanie says
July 24, 2018 at 10:09 pmCame out absolutely PERFECT!!!!!!!!!!!!!!!! Thank you! I will use this many more times. :)
★★★★★
Randall says
July 22, 2018 at 2:44 pmThis is the absolute best dessert recipe I have found/tried since going Keto. So close to the “real thing”. Thank you SO MUCH! The only things nag I changed were using Lakanto sweetener instead of Swerve and straining the mixture after adding the gelatin and xanthan gum to ensure totally smooth texture. My Kids even love them and they are the hardest to please as they are used to me making standard desserts and pastries that are extremely high in carbs. Your site has been a godsend to us through this transition. Thanks again.

Rachel says
June 22, 2018 at 1:11 amI may have forgot to strain. Oops! But it was so creamy and smooth and tart and AMAZING! Seriously. I am so happy about this.
★★★★★
Kristin says
June 20, 2018 at 1:51 pmThis is the first comment I have ever left about a recipe, it’s that good! I am an avid baker, cook most meals from scratch and have been struggling to find a good low carb dessert. This is perfection, I just can’t wait for my lemon trees to have ripe fruit to make more! I did add a pinch of salt to both the crust and filling. I have Myer lemoncello that I made from my trees and I added about a tablespoon. I know that increases the carb count but it was a indulgence I was willing to make. I cooked down some blueberries for the kids and husband to use as topping and all love it. Thank you!

Caroline says
May 28, 2018 at 4:54 pmThese are perfect. Made them for a group in which I’m the only keto weirdo, and no one guessed I’d bested them. Praise all around. That is the true test!
(Other true test: I currently have what’s left hidden in the back of the fridge for my. mouth. only.)
Courtney says
May 23, 2018 at 8:42 pmBest baking Keto recipe so far! I loved these and they were the perfect balance of tart and sweet for my taste. Definitely will be making these again and also for a work function this week.

Mellissa Sevigny says
May 24, 2018 at 9:25 amHi praise, Courtney – thanks so much!!! Hope they are a hit at work too!
Caitlin says
May 14, 2018 at 8:10 pmI absolutely LOVE this recipe! I never give reviews on anything, but since I just finished enjoying my dessert (these bars) I thought I should probably post a review because I love them that much! One commenter said these taste like the real thing, and they totally do! I baked the crust a little longer, until it was golden brown so it would be a little crispier and it turned out great! I also omitted the xanthan gum and used 1 packet of Knox gelatin for the curd (which some other commenters suggested). I’m in trouble…. :)
Mellissa Sevigny says
May 15, 2018 at 8:41 amThanks for reviewing it Caitlin, glad you liked it!
Marie says
May 27, 2018 at 9:38 pmCaitlin,
I was thinking of omitting the xanthan gum as well. I don’t use gums in my kitchen and I don’t see the need for it. I intend on using Great Lakes Bovine Gelatin.
Wendy says
February 26, 2019 at 4:36 pmMarie,
Did u try it without the gum? I was thinking the same thing. Like to know what you did.
Isabel says
May 14, 2018 at 12:11 pmI made these yesterday and they turned it delicious. Thank you so much!!
★★★★★
Lindsey says
May 14, 2018 at 1:32 amThese were a huge hit! I may leave the xantham gum out next time because the tip was rubbery and more firm than it should have been so maybe the gelatin is enough. But otherwise delish and perfect for spring.
★★★★★
Keri says
April 25, 2018 at 8:10 pmCan’t wait to make them … is it ok to use Knox unflavored gelatin
Mellissa Sevigny says
April 25, 2018 at 8:47 pmYou can, but only use 1 tsp.
Leila says
April 15, 2018 at 6:27 pmWow! Another amazing dessert! I don’t know how you do it, but these recipes are incredible. I’d never know this was keto if I hadn’t made it myself! Delicious!
Kristina says
March 29, 2018 at 5:51 pmThis recipe looks fantastic, I’m looking forward to making it for Easter! Is it possible to substitute a GF All Purpose Baking Flour for the Almond Flour? I have Bob’s Red Mill in the pantry, and would prefer to use ingredients on hand rather than buying more if possible. Thanks!
Mellissa Sevigny says
March 30, 2018 at 10:04 amI don’t think that will work the same as the almond flour Kristina – but if you try it let us know!
Jen says
February 4, 2018 at 5:19 pmOk, these did not work for me. I should have baked the crust longer, because it was cake not crispy. Also I think the curd should have been left as is without the gelatin and xantham gum. I used Knox gelatin, so maybe that was why, but the top was rubbery. I froze them hoping eating them frozen will make them better. I will eat them cause I hate to waste, but I will try a different recipe next time that doesn’t require special gelatin.Jen
Jen says
February 10, 2018 at 6:48 pmOkay, they are much better frozen. I ate the whole batch this week.
MissTris says
February 1, 2018 at 10:51 pmAbsolutely Delicious! These were plenty sweet for hubby and me with just the 1/2 cup of Swerve in the filling. Next time I would probably put only 3-4 Tbsp. of Swerve in the crust and maybe even dial back a bit on the Swerve in the lemon filling. One packet of Knox gelatin worked great for me with the xanthan gum. My husband said they tasted just like the regular sugar-filled lemon bars, and he liked the almond crust even better than the typical wheat crust. Soooooo happy to find this recipe! Thanks!
Pamela C says
January 27, 2018 at 1:08 amDo you have a nut-free adaptation? My hubby lives lemon bars but is allergic to almonds… Thanks!
Ellen Stewart says
January 29, 2018 at 11:25 pmI used coconut flour instead of almond flour and it worked just as Well! I’m allergic to nuts as well.
Angela says
June 27, 2018 at 4:52 pmHow much coconut flour did you use? I am not a huge fan of almond.
Jennifer says
January 22, 2018 at 3:56 pmWould the filling still thicken without the xantham? I’m paleo so can’t use it x
Olivia says
January 22, 2018 at 2:42 pmThe taste of the custard was great – tart and very lemony (yum!!). The crust was just ok, I might try with more Swerve next time in the crust, by the next day it had no flavor but the texture was perfect.
The texture of the custard on day 2 (very firm) was not to my liking. I will use half the gelatin or even maybe 25%. I like my lemon bars gooey.
This is a great recipe to start with for low cal!! Thanks so much!!!!
Toni says
January 11, 2018 at 12:56 amHow many lemons to get 1/4 cup zest?
Olivia says
January 22, 2018 at 2:35 pmI think it was 3 when I did it.

Lindsey says
May 14, 2018 at 1:30 amI used quite a few for 1/4 cup of zest… probably about 8-9.

Lisa says
December 24, 2017 at 2:12 amI pulled this off the stove early after adding the yolks. I did strain it after & then again after adding the gelatin & xantham gum. It turned out pretty good but how long did you cook the custard/curd before taking it off the heat?
Ashley says
November 28, 2017 at 1:42 pmHi! I love this recipe & can’t wait to try more! I ACCIDENTALLY used the whites instead of the yolks, LOL! I put them into a cupcake tin to make ‘tarts’ as well, they are WONDERFUL!!! (After fully cooling, before that the crust got a bit soggy,maybe from so much egg whites?) I think I’ll use whole eggs next time to save the separating & not waste the whites- since I now know it can be done with all whites & no yolks, lol!
Thanks for all your hard work!
Ashley Wright says
December 24, 2017 at 12:48 amPerfect!

Mommy Tties Keto says
October 20, 2017 at 12:41 amThis is, by far, the best dessert I’ve made following s Ketogenic diet. I used xylitol and there was zero aftertaste. They taste exactly like a “regular” lemon bar. So so yummy! Next time I make them, I’ll double the curd because it’s just that good!
Thanks for this! You made this mama and her brood very happy!

Kelly Jackson says
September 1, 2017 at 9:36 amThank you so much! These were the first low carb dessert that I have made that I really couldn’t tell they were low carb. I made them to take to a party and they were a huge hit! The only gelatin I had was Knox – I used one packet and they turned out perfect. I am going to make them again today to take to a get together – I am going to attempt to make in a tart pan – have you ever tried to make them a tart pan? Do you think it will affect cooking times?
★★★★★
MoodyMoody says
August 1, 2017 at 9:36 pmIs it okay to use Splenda or stevia with this recipe instead of Swerve? My husband is super-sensitive to erythritol, to the point where he can’t use Truvia at all without explosive diarrhea. (Pure Via without erythritol is fine, so it isn’t the stevia itself.) I’m always a bit hesitant to substitute blindly in baked goods because of bulk or chemical differences in the final product. My husband wants to reduce his carbs, but a lot of the standard substitutions cause digestive issues for him.

Summer says
March 11, 2017 at 9:28 amHi! I’d love to make this recipe … I have xanthum gum but don’t have the collagen. I have Knox unflavored gelatin but see in the comments it’s not the same thing – can I just leave that ingredient out? Does it affect the outcome of the recipe? Thanks
Mellissa Sevigny says
March 12, 2017 at 3:57 pmYou can use the gelatin but only 1/3 of the called for amount should do the trick!
Kim says
January 14, 2017 at 3:06 pmThis recipe looks fabulous – I look forward to trying it after I get some ‘green can’ Great Lakes collagen. In the meantime, do you have handy the rest of the nutrition info, like grams of fiber and micronutrients (sodium, potassium, calcium, etc.)? I appreciate the net carb info but I’m trying to get a certain amount of fiber and other nutrients every day and this additional info would help. If not, I can calculate all the ingredients myself to figure it out…just thought you might already have it. Thank you.

June 17, 2016 at 11:14 pmThank you SO much for this recipe!! I made them today and they turned out amazing! I’m enjoying a piece with my tea right now. I wanted to make hubby a treat for Father’s Day, and these were just perfect. Watch me eat most of it…lol!!
Btw, I used one packet of Knox gelatine and didn’t have any issues.
I tried doing low carb without having any type of low carb treats, and crashed hard after 3 weeks. Now I’m back on and learning to make low carb desserts that will help keep me from falling off again.
Can’t wait to try out some of your other recipes!
Claire says
June 13, 2016 at 10:09 amI made these and they turned out beautifully. However, I think the curd was too hard once cooled. I would use less gelatin next time. I also would prefer a more intense lemon flavor. Maybe more juice or leave in a small bit of zest would help with that. I would also make the curd a little sweeter.
★★★★
Amber says
May 29, 2016 at 7:57 amHi! Do you think it matters the type of gelatin? I am about to make these, and am heading to store, but I don’t think we have Great Lakes gelatin here. I’ve never baked with unflavored gelatin. Is it powder or liquid? No clue what I’m doing with this. Any tips on what to buy would be greatly appreciated! 😊
Eryn says
May 10, 2016 at 2:42 pmHi, I was so happy to find this recipe as my Mom used to make some delicious lemon bars when I was a kid. The thought of them just makes me happy. I was eager to make these, but I didn’t have xanthan gum, so I substituted chia seeds. The filling seemed a bit soft when removed from the oven and then cooled. It tasted great nevertheless. I have placed them in the fridge overnight and they are certainly firm now. Thanks for this deliciousness.
★★★★★
Lisa says
May 7, 2016 at 5:16 pmVery Nice recipe but the gelatin seized up and made curds! After I strained it. So that was unfortunate. A bit extra texture. So I covered it with a layer of cream cheese and sour cream. And made a totally new desert.
★★★★★
Lara says
September 5, 2016 at 4:32 pmShe used land o lakes green “gelatin” it doesn’t gel. So if you’re using actual gelatin, even land o lakes it won’t turn out the same. The green is great to mix in drinks and what not to get your dietary supplementation but not for gelling as it stays liquid…
MissTris says
February 10, 2018 at 5:29 pmIt’s “Great Lakes” gelatin, not “Land o’ Lakes.” Just looking to avoid confusion. :-)
Rhonda says
April 10, 2016 at 6:06 pmNot sure what I did wrong. I subbed coconut flour because of alergies but that is the only change I made. My crust ended up about 2 inches thick and didn’t hold together at all. I mixed it, it seemed really dry but I used the right quantities so I went with it. Baked it 10 min and it still seemed wrong but I just kept going. In the end I ended up with 2 inches of what was basically flour under my custard. Well the flour is expensive so to salvage it, I mixed the whole mess together, added a ton of oil and some egg whites, and put them in my brownie pan, now they’re more like lemon blondies. Any ideas on what the problem might be? 2 cups of flour seemed to be way too much. I’ve checked the recipe about 5 times to make sure I didn’t miss something. I am going to try again but I may cut the flour in the crust in half, or even less
Mellissa Sevigny says
April 10, 2016 at 6:13 pmCoconut flour and almond flour are not equally interchangeable. 2 cups of almond flour – or find another coconut flour crust to use as a base and just make the filling to put on top.
Rhonda says
April 11, 2016 at 7:56 amI’ll just use way less coconut flour next time as 2 cups of almond flour could potentially kill m. I’ll play with it and see what I come up with and then comment back here in case anyone else has an allergy
Lara says
September 5, 2016 at 5:12 pmThere a plethora of coconut flour crust recipes, found this on my first search.
http://www.sugarfreemom.com/recipes/low-carb-coconut-flour-pie-crust/
Also found this on substituting:
1.Coconut flour absorbs a lot of liquid. For every 1 cup of coconut flour, use 6 eggs and 1 cup of liquid.
2.1 cup all-purpose flour = ¼-1/3 cup coconut flour.
3.Coconut flour can be baked at the same temperature as other recipes, no need for adjustment.

October 21, 2015 at 2:54 amYum! I’m not sure if I didn’t bake them long enough, as the lemon curd part stayed somewhat soupy, but…no matter! I ate them with a spoon, and they were still delicious! Thanks for the recipe!
Amanda says
October 22, 2015 at 1:01 pmUpdate: They firmed up in the refrigerator…and remained delicious! I can’t wait to make these at Christmastime!

October 4, 2015 at 8:41 amYou could probably reduce it to 1 Tbsp if you’re using regular gelatin!
Amanda says
August 3, 2015 at 8:19 pmThese are delicious and it’s a great recipe. Unfortunately there is one very important huge problem: they aren’t really keto friendly. I’m wondering how u got 2net carbs each. My mom made these & i binged on them without doing my own calculations and got really really sick (out of ketosis & sugar alcohol overload). Doing the calculations for the crust ALONE with 1/3 cup swerve and 16 servings, it is WAY over 2g carbs.
According to my math for the whole recipe, calculating NET CARBS even for the almond flour, there are AT LEAST (being minimally liberal) 15 GRAMS OF NET CARBS PER SERVING. That’s more than I usually eat a DAY. (Oh my god no wonder I was sick for 2 days. I’ve been working at keto adaptation for a month and a half & want to cry).
***PLEASE PLEASE PLEASE DO NOT EAT THESE IF YOU ARE ON KETO!!!!*** at least 15 carbs a serving!
Mellissa Sevigny says
August 5, 2015 at 9:02 amYOU ARE INCORRECT. CALM YOURSELF. The sky is not falling and these lemon bars are PERFECTLY KETO FRIENDLY when the nutrition information is calculated correctly and you don’t “binge” and eat the entire pan. One batch of crust and filling has a total of 36 grams of net carbs – when you divide that by the 16 two by two squares that constitute one serving, you get 2.25g net carbs per square. You got sick and kicked out of ketosis because you ate too many – my recipe is not to blame, your lack of moderation is.
Amanda says
August 5, 2015 at 10:56 amSORRY! I was freaking out. I’m brand new to Erythritol and did not understand that the listed sugar carbs in that sweetener are completely indigestible and apparently don’t count at all. Your recipe is superb.
Susan Huth says
April 18, 2019 at 1:06 pmLove your reply! :D
I have a question about lemon juice. Approx how many lemons in the recipe? Also, what do you think about using bottled “real” lemon? But then there is the zest… hmmm.

July 13, 2015 at 11:17 pmHi there –
I’m new here and I love this site. I’ve made the snicker doodle crepes, cream cheese pancakes, pepperoni cauliflower pizza, and they turned out great. My grocery store didn’t have almond flour, so I used coconut flour for the lemon keto bars, and they didn’t turn out so well. I’ve never used almond or coconut flour before, but I’m thinking they’re not interchangeable. There are so many other recipes I can’t wait to try!
Mellissa Sevigny says
July 14, 2015 at 8:54 amHi Caitlin – for sure the almond and coconut flours are not interchangeable so I can see why you would have had trouble with the lemon bars recipe! I hope you’ll try it again with the almond flour because they are awesome! I get my almond flour online through Amazon because it’s so much cheaper than the stores! Also get a very fine almond flour like Wellbee or Honeyville for the best results in baked goods!
CaitlinBrooks says
July 14, 2015 at 11:05 amThanks Mellissa. I will order the almond flour. I appreciate the guidance, and I will try the keto bars again as the lemon part is awesome it was just the crust that was off. I’m using the left over egg whites to make the meringue cookies! I’ve done low carb off and on forever but all this creative baking is new to me! This site is beautiful!

June 6, 2015 at 6:28 pmtried second time, split in the curd process..recipe has become too expensive..I’ll use crust for something else.. very sad as i love lemon.
Lara says
September 5, 2016 at 4:27 pmShe said she used the green land o lakes gelatin which doesn’t gel. It’s just collagen. That’s probably why it split ☹️
vicky says
June 6, 2015 at 5:55 pmcurd was lovely but when i added xanthan gum and gelatin it split. So sad.. Im going to try them without xanthan. reminded me of when cornstarch makes lumpy gravy
Dianna says
May 31, 2015 at 7:02 pmI don’t have any lemons, to make the zest, ….. can I use just lemon juice purchased in a bottle?
Mellissa Sevigny says
June 1, 2015 at 11:06 amYou can Dianna, but the flavor will be less intense and possibly too sharp without the zest to round it out. Not horrible, just not nearly as good as with the zest!
diana says
May 26, 2015 at 6:18 pmWell, I almost NEVER comment on a recipe that I haven’t made yet, but just gotta say, I am sure this is the one I’ve been looking for–lemon curd over an almond crust. Just have to get through the fabulous lemon pound cake with lemon glaze I made to go with the whipped cream and just-picked strawberries before I can get to this! Thanks–I’ll report back as soon as I make them!
Mellissa Sevigny says
May 27, 2015 at 1:30 pmThe cake sounds amazing – hope you like the lemon bars just as much! :)
debbie says
May 26, 2015 at 12:56 amHi Mellissa! Planning to have this for my daughter. I wonder what can be a good substitute to almond flour? She’s allergic to gluten, nuts, soya. Thanks in advance!
Mellissa Sevigny says
May 26, 2015 at 6:24 amAny cookie crust or sweet base layer will probably work so if you can find one that will work for her just top it with the filling and bake!
Michelle says
March 7, 2017 at 12:50 pmIs xanthan gum A necessity? I’m seeing more more of this with the recipes I guess I just got to go break down and buy some but I’m so new I have no idea what to get :-)

Leigh Ann says
May 11, 2015 at 1:16 pmI’m so glad I found this! I’ve been doing ultra low carb for 5 weeks now, and lemon bars are my absolute favorite dessert.
Mellissa Sevigny says
May 13, 2015 at 12:48 pmI’m glad you found it too Leigh Ann – hope you like them as much as we did!
Amanda says
April 30, 2015 at 12:58 amWhat do you use to strain the filling? Would a metal mesh strainer work?
Mellissa Sevigny says
April 30, 2015 at 7:15 amYes Amanda, that would be perfect! It just needs to be fine enough to strain out any larger chunks of lemon zest or any lumps that might have formed while making the curd!
BarbaraLK says
April 29, 2015 at 11:39 amOdd question … I have never figured out how to really zest a lemon. I have a fine grater/zester but it really doesn’t seem to work.
Tips? Suggestions? I am impaired in some things … :)
Mellissa Sevigny says
April 29, 2015 at 11:43 amI find that my microplane grater works the best – some zesters are too small and they just grind it into mush making it hard to use. This is the one I have and it works great on lemon, parmesan, chocolate, etc. You can find all kinds of brands and price points in this basic style – even at your local department store probably!
barbara says
May 1, 2015 at 9:42 amThanks! I have one but I seem to get just goo. Maybe I am doing it wrong. I will try again. :)
Mellissa Sevigny says
May 2, 2015 at 9:09 amThere are different blade sizes that will give you a fine grate or a courser one – sounds like yours is too fine so go a size up and you should be good!
Kelsey says
April 25, 2015 at 5:32 pmUh…are these still low carb if you ate a third of the pan in one sitting??? Holy Hannah Montana these are tastey.
Linda Buie says
June 10, 2015 at 7:48 pmI fear making them because I think I will eat all of them in one sitting. :)
Ainsley says
April 22, 2015 at 4:29 pmGreetings Mellissa <3
I was just nomming on your bison beer braised meatballs with cauliflower mash yesterday and was actually happy swaying from how good they were, I did use regular old ground beef but it was still amazing. Especially on the second day.
But on this recipe I made it a few weeks ago and kept forgetting to ask, my bars are amazing and taste fairy level amazing when heated up but when I tried to eat them cold the yellow lemon part would fall off of the crust. To avoid this would I just use less gelatin? I used the Great Lakes one.

Mellissa Sevigny says
April 22, 2015 at 5:34 pmHi Ainsley, glad you’re enjoying the meatballs! Regarding the lemon bars, it’s weird that the lemon part didn’t bond to the crust. I wonder if it IS an issue of the gelatin. Was it super hard, because if so that could be it? Or maybe if the cookie layer baked too much they didn’t bond together after you added the lemon curd. I’m totally stumped on that one but I would try it next time with less gelatin and see what happens. Or omit the xanthan gum and keep the gelatin the same. Glad they tasted good though!
Ainsley says
April 22, 2015 at 5:57 pmHmm…I believe experiments are required…for science. I may have baked the crust too long or maybe my crust was too thick, because now that I’m looking at the pictures mine was much thicker. I failed to follow directions. Next time I’ll omit lessen the gelatin and cook the crust longer.
Thanks so much =)
richard schmidt says
April 21, 2015 at 5:01 pmthese look so good. i want to make them for my Quaker meeting this Sunday, but i dont use sugar. can i substitute honey or agave or maple syrup instead?
Mellissa Sevigny says
April 21, 2015 at 7:27 pmAny of those could work but I’m not sure of the quantities.
richard schmidt says
April 21, 2015 at 7:39 pmcooks.com says either 1/2 or 2/3 cup honey equals 1/2 cup granulated sugar-but then also says to reduce the other liquids.now THAT sounds like it could be tricky
Mellissa Sevigny says
April 22, 2015 at 12:46 pmYes, I think you’ll have to experiment a bit. Agave is the sweetest and will probably take up the least amount of volume so you might get away with a little less since there isn’t a lot of room to reduce liquids in this recipe. Let us know if you figure out a way to make it work!
Ruth Hadlock says
April 12, 2015 at 1:09 amGreat recipe! The crust is soo good, I have a question about the filling – did anyone else’s filling turn to rubbers with 2 tbsp gelatin? I used the powdered gelatin in the box. Wondering if next time I should use 2 tsp. instead of tbsp? Thanks for then yummy recipe! I loved all that real lemon! I didn’t event strain it because I wasn’t sure what I was supposed to be straining!
Mellissa Sevigny says
April 15, 2015 at 8:35 amHi Ruth! I used Great Lakes Gelatin which may act differently than the powdered gelatin in the box so if you got a rubbery texture then definitely use less next time! Glad you liked the flavor! I strain out the lemon zest to get a smoother texture in the bars, but it’s definitely not a requirement if the texture didn’t bother you! Thanks for weighing in!
Audrey says
April 11, 2015 at 4:14 pmI made these Lemon Bars yesterday…but made them into little tarts using muffin tins & altered the crust a bit by using Coconut Flour…but they turned out FANTASTIC!! Thanks so much for the recipe!! :)

Mellissa Sevigny says
April 15, 2015 at 8:36 amLittle tarts sounds adorable – totally stealing that idea Audrey! Glad you liked them!

April 6, 2015 at 2:30 pmHi Melissa,
Thanks so much for sharing all your hard work and delicious recipes with us. I tried these Lemon Bars and they were just like the real deal, so I was very excited to be able to have them again after eliminating sugars and grains from my diet. They were light, tangy and felt like a great Spring treat! I did have a few problems while making them though that I wanted to ask you about. First of all you said 1/4 cup lemon zest and I wondered if that was the correct amount. I had to use 8 lemons and I was still shy of that amount. Also, when I went to strain the lemon curd, all of the zest was caught in the strainer, is it supposed to do that? Also, as I was cooking the filling it started to turn a putrid green color and I don’t know why. I had to add a bunch of yellow food coloring to it and they still turned out an unattractive yellow-green color. They still taste great, but I am wondering what I may have done wrong since yours are such a pretty yellow color. Thanks for your help.

Mellissa Sevigny says
April 8, 2015 at 8:06 amHi Peggy! I’ve eaten the curd without straining it but not everyone likes the texture of all the lemon zest in it which is why I recommend straining it out. 8 lemons should have given you more than enough zest – were you using a micro plane grater made for zest ink, or something else? Regarding the color, sounds like it may have reacted with your pan. Acidic foods like lemon will turn a weird green color in a metal pan sometimes. Try it in enamel or a coated nonstick pan next time and you should get the bright yellow natural color with no need for food coloring! Hope that helps, glad they tasted good at least!
Brenda says
April 1, 2015 at 9:34 amOkay, found my Easter dessert. Thanks so much. If these are even half as good as the raspberry cheesecake bars, I’m going to be one happy camper. I’ve been following the menu plans (on week 3, now) and I have to say that EVERYTHING I’ve made from your site is delicious. EVERTHING. That ususally doesn’t happen. I cook a lot, and sometimes I look at ingredients you have listed and a little doubt comes into my mind, but it’s always swept away by the final product. I’m dying to make the General Tso’s meatballs again, and the chicken salad you just posted looks incredible. I’ve lost about 7 lbs, and most importantly, busted through a number on the scale that I haven’t been able to breech in over a year. Thank you again for all your work. It is MUCH appreciated.
Mellissa Sevigny says
April 2, 2015 at 5:55 amCongrats on being the boss of your scale, so happy that the plans are working for you!!! As for these lemon bars I like them even more than the cheesecake bars so you’ll have to know what you think once you try them!!!
Debbie says
March 27, 2015 at 5:46 pmCan you use the green can gelatin or do you need the red can kind? Thanks.
Mellissa Sevigny says
April 2, 2015 at 6:13 amI used the green can gelatin Debbie and it worked great!
Leslie says
June 3, 2016 at 1:11 amI wondered about this… The green can of Great Lakes is collagen, not gelatin, so it doesn’t set like gelatin. Maybe that’s why folks who used gelatin had issues? I am definitely making these this weekend, but they will be coming to work with me Monday morning so I don’t eat them all :)
Amy says
August 26, 2016 at 12:23 pmI had a question about this too. I’ve made this twice and used Knox Orinal Gelatine. Is there an advantage to using the one listed in the recipe?
Jammie says
March 8, 2017 at 2:48 pmDo you have to use gelatin in the recipe. Are there any substitutes?
★★★★
jessie says
March 27, 2015 at 12:15 pmis the filling firm enough to stand up without the crust?
Mellissa Sevigny says
March 27, 2015 at 4:26 pmIt’s pretty firm but you’d have to chill it well and probably cut it into one inch squares.
Eric says
March 27, 2015 at 11:23 amWelcome to spring(?) in the Hudson Valley! I’m just north of you in Dutchess County, and the view out of my window is still as arctic as yours. Sigh. Love lemon bars, though, so these will help to get me through the next few days as the crud melts. Thanks for posting, and good luck with the rest of your moving chores.
Mellissa Sevigny says
March 27, 2015 at 4:18 pmThanks Eric!!! It’s above freezing today so I’m optimistic that the snow bank out front will be gone soon! Hope you like these!!!

March 27, 2015 at 10:43 amWelcome, back, Melissa :) These look great. I’m going to have to get over the reluctance to separate eggs for recipes and make these.
