These Keto Coconut Lime Bars boast a crispy, buttery cookie crust and a tangy lime filling that is to die for! Also, they are basically a super food. You’re welcome. 😂
This Keto Coconut Lime Bars recipe was the last one I created before we moved from Belize to Roatan, Honduras, and it was kind of fitting because limes are a big part of life in Belize. Not only do they make delicious cocktails, they get squirted onto all manner of foods before serving.
When we first moved to Belize I assumed people loved limes for the flavor, but in fact it’s believed that limes can cure just about any ailment. We have a Mayan friend named Irma who suggests limes as a treatment for everything, and Mr. Hungry gets a huge kick out of it. Got a headache? Lime juice. Cold or Flu? Tea with an entire lime squeezed into it. Cut on your leg got infected? Rub half a lime into it. Arthritis? Gout? Acne? Stomach bug or parasites? Seriously – limes for EVERY. THING.
As a side point, I don’t think I’ve ever seen Irma get sick, I’m just saying.
Mr. Hungry likes to joke that a Mayan pharmacy is just shelves full of fresh limes. Of course that isn’t true – I’ve actually got some really cool Mayan ointments and elixirs that straight up work miracles on all kinds of ailments, though there is likely some lime in there somewhere too, ha ha.
So my point is – these Keto Coconut Lime Bars??? Basically next level Mayan health food. You’re welcome.
Full disclosure, I ate three of these Keto Coconut Lime Bars in one sitting and I make no apologies for it!
Once you taste that crispy, buttery crust, topped with the creamy, tangy, coconut lime filling – you’ll understand. In fact, I’m pretty sure you’ll be hiding these tasty keto treats behind the broccoli and telling no one about them–otherwise they’ll be long gone before they even have time to chill all the way through!
All joking aside, these may not cure a cold or that strange rash you suddenly developed (seriously, you should get that checked out tho) but they will cure your keto dessert cravings, and that’s still a pretty great reason to make some STAT.

Susan Kelly Montgomery says
This is my go-to keto dessert! I love lime and coconut together, and the flavours in these lime coconut bars meld so well that you’d never know there’s no sugar. They are melt-in-your-mouth delicious. I chuckled at the comments asking about how they keep, because we never have any left over!

Danielel says
Could these work substituting coconut oil or ghee for the butter?
Mellissa Sevigny says
Yes, I recommend ghee for flavor but if you use coconut oil add a pinch of salt.
Cammi says
Made this as written a week or two ago and it was a big hit. Today, we’re switching it up with lemon juice instead (per my son’s request) and it’s baking (and smelling yummy) as I type away. Thanks for another great recipe.

Angilyn Bagley says
This was a hit with my family! Loved it!

Denise says
Easily the best keto thing I have ever made! Thank you so much! I followed the recipe exactly and they are perfect. Going to make batch #5 now ?
Mellissa Sevigny says
That’s awesome Denise, thanks so much for letting me know!!!
Joey says
These look amazing and I can’t wait to make them. I’m worried that an 8×8 pan won’t last long enough. Do you think if I doubled the recipe it would work the same in a 9×13 pan?
Grace Hafer says
I’m not much of a commenter, but I’ve been following you and making your food since 2014 and this is my FAVORITE dessert so far. Added a few drops of coconut extract to my filling – so amazing!!
Mellissa Sevigny says
Thanks so much for taking the time to comment Grace! I’m impressed that of all the desserts you like this one the best – it’s one of my new favs too!!
Myrna says
Totally awesome! If you like key lime pie these are your low carb answer. This recipe is a little more involved that just measure, dump, stir and bake, and it’s totally worth every minute and every dirty dish to make it. Thank you Mellissa for another winner.

Mellissa Sevigny says
Thanks Myrna, glad you liked this one too!
Lulu says
Lovely! Thank you!

Kindra Pladies says
These look amazing, Melissa! I’m saving the recipe for after the 30 day keto cleanse I’m doing. On a tangent, do you have any advice for staying keto while visiting Roatan? We will be renting a home there in May on vacation for 10 days and making our own meals. I’m trying to figure out how to plan for meals and what I need to bring with me versus having access to at the grocery store.
Mellissa Sevigny says
Find Eldon’s – its a large supermarket and it has everything you’ll need!
Shelley Jackson says
I can’t wait to make these, however, I’m wondering if i could use Swerve confectioner’s instead of granulated?
Mellissa Sevigny says
Yes that should work fine Shelley!
Susan says
Made these tonight and they were fabulous! Thank you!

Mellissa Sevigny says
Thanks so much Susan, glad they were a hit!
Julie says
I’m visiting Roatan standing in my parent’s kitchen (they live here) and looking for a fabulous keto recipes to use some fresh picked limes and I see this post. Yum! Where in Roatan are you?
Mellissa Sevigny says
We’re in Parrot Tree Plantation Julie – leaving for the states for 3 weeks tomorrow though! Enjoy your trip!
Deborah Douglass says
Oh my goodness! Finally a lime bar (could be a yummy lemon bar, too) for us sugar free, grain free folks! These are delicious! My only change: I used Trim Healthy Mama Gentle Sweet for the sweetener. Perfect! But, my crust did not brown or crisp up like yours, even though I baked it on the lowest rack like I do pies. Any suggestions?? I will say that even without the lovely golden crust, I will make these again and again! Thank you for sharing with us!!
Mellissa Sevigny says
The erythritol sweetener caramelizes and gets golden like sugar and I’m guessing the THM sweetener does not. Glad you enjoyed them Deborah!
Debbie Holmstrom says
Is erythritol sweetener Stevia?
Mellissa Sevigny says
No. Stevia and erythritol are completely different.
Hayley says
How do you think this would turn out if I omitted the xanthan gum? It is very difficult for me to get or find in any stores. Would gelatin be enough?
Mellissa Sevigny says
You should be ok Hayley, might be a little soft but that’s not a bad thing!
annette gaskill says
sounds delish… have you tried this with lemons…?
Mary says
These look amazing! I am a huge Key Lime fan and think I will sub Nellie and Joe’s key lime juice, nonetheless, thank you for your inspiration ❤️
Dee says
Can’t wait til I can munch on these Bars. Thanks, as usual, for all your hardwork!!! One thing other LCarbers should know is that all your recipes turn out beautifully — unlike some other website recipes that I have visited.

Mellissa Sevigny says
Thanks so much Dee!
Adrian says
Why use double the gelatin if using Great Lakes instead of, say, Vital Protein brand…or some other brand…of gelatin?
Mellissa Sevigny says
Vital protein would probably be similar to Great Lakes but if people are using Knox or another extremely firm gelatin they are getting a rubbery texture with 2 tablespoons.
Matt says
These were really good! And I feel better already.
Chef William says
Great Recipe, I will make this when I visit our house in the states. While we have limes everywhere here in Mexico and use them with just about everything we eat, butter is a completely different matter and this recipe does use a lot of butter. Because as part of my ketogenic diet, I only use butter from grass raised cows I have a limited supple. However that is not the problem in the states so I will enjoy these next month.
Jennifer says
I can’t wait to try this. I always use less Truvia/sweetener than called for because it tastes too harsh to me (other people have a sweet tooth so I get it). I really like your site and hope you don’t mind if I live vicariously through your travel updates just a smidge. :)
