These Keto Caramel Nut Chocolate Brownies are everything you’ve ever wanted in a low carb brownie, and so much more!

Fudgy chocolate brownie layer? Check! Sweet, oozy caramel? Check! Crunchy walnuts? Check, CHECK! Seriously – these Keto caramel nut chocolate brownies are so good you’ll never know they are low carb!!!
Let’s break it down…
The low carb chocolate brownie layer is super chocolatey and just sweet enough. It’s tender, and fudgy, and…perfect. The texture is much firmer when refrigerated, but I prefer them at room temp or even slightly warm because the chocolate bits are soft and melty on the inside, and the caramel will be softer too. The whole thing just melts in your mouth, but you also have the pleasant texture of the walnuts on top to keep it interesting. You’ll see…

The keto chocolate brownie layer is made primarily with almond flour – to get the right texture you’ll need a super fine blend – a really course almond “meal” won’t work nearly as well. There is a small amount of coconut flour in these as well – you can replace it with more almond flour if you have a coconut allergy, but it may affect the texture a bit.
I used chopped walnuts on top of these, but you could use almost any nut in place of them. Pecans, almonds, or even pistachios would work great.

Now how about that caramel?
YUM.
I used half and half instead of heavy cream, because the small amount of milk sugar gives it a more authentic flavor and color. It also helps this Keto caramel stay soft when it cools, making it more pleasant to eat. The bourbon adds a nice flavor to this caramel, but it also helps it to keep from solidifying as it cools.
If you opt to leave the bourbon out, replace it with an extra 2 Tbsp of half and half to compensate.
I’ll be experimenting more with this Keto caramel recipe, because it makes a fantastic Keto caramel frosting when whipped after it’s cooled, AND with a few little tweaks you have keto friendly caramel fudge!
So many delicious applications for this low carb caramel recipe – but on these Keto caramel nut chocolate brownies?
Total bliss.

Keto Caramel Nut Chocolate Brownies – Low Carb
- Yield: 16 brownies 1x
Description
A delicious keto chocolate brownie recipe drizzled with caramel and chopped nuts. Gluten free, keto, lchf, low carb and Atkins diet friendly!
Ingredients
For the brownies:
- 1/2 cup butter, melted
- 3/4 cup almond flour
- 1 Tbsp coconut flour
- 1/3 cup granulated erythritol sweetener (Swerve or other)
- 1 tsp vanilla extract
- 3 large eggs
- 1 egg yolk
- 1 tsp baking powder
- 1/4 cup good quality cocoa powder (for baking)
- 1/4 cup 90% cocoa (or more) dark chocolate, chopped
- 2 Tbsp sugar free chocolate flavored syrup (torani or davinci style)
For the caramel:
- 3 Tbsp salted butter
- 1/3 cup erythritol granulated sweetener (Swerve or other)
- 1/3 cup half and half
- 1/4 tsp xanthan gum
- 2 Tbsp bourbon
- 1/2 tsp caramel flavoring (aka “extract”)
To assemble:
- 1/3 cup chopped walnuts (or any nut)
Instructions
To make the brownies:
- Combine the melted butter, almond flour, coconut flour, sweetener, vanilla extract, eggs (and yolk), , baking powder, cocoa powder, chopped chocolate, and sugar free chocolate flavored syrup in a medium bowl.
- Stir lazily by hand until fully combined – don’t beat or whip or you’ll end up with a much cakey-er texture.
- Pour into a parchment or foil lined 8×8 square pan.
- Bake in a preheated 375 degree (F) oven for about 12-13 minutes, or until the center no longer jiggles when you gently shake the pan.
- Remove and cool before slicing.
To make the caramel:
- Melt the butter and sweetener together in a small saucepan over medium heat.
- Cook, stirring constantly for about 2 minutes or until bubbling.
- Add the half and half, xanthan bourbon, and caramel flavoring.
- Whisking continually, cook for 3-5 minutes over medium heat.
- It will get darker in color the longer you cook it.
- Remove from heat when your desired color is reached.
- Let it cool slightly to thicken.
To serve the brownies:
- Remove the brownies from the pan and peel off the parchment or foil.
- Add the cooled caramel to a small plastic ziplog baggie, then cut about 1/8 inch off of one of the bottom corners of the bag.
- Gently squeeze the caramel over your brownies – you may have some leftover.
- Sprinkle your chopped nuts evenly over the top of the brownies.
- Then cut into 16 brownies (2×2 squares.)
- Best served at room temperature, but if you are keeping them more than 24 hours, store in an airtight container in the refrigerator.

This looks soo delicious And I have missed Luna since going gluten free.
Erica says
White chocolate macadamia, please. I’m trying these out soon. I need to bring something for our holiday potluck at work. One question: If I omit the caramel flavoring, would the topping still have a good flavor? No time to order the flavoring online and they don’t carry it at my store.
Mellissa Sevigny says
The longer you cook it, the more of a caramel flavor it will have Erica – but I got mine at Walmart (Watkins brand) so you might be surprised to find a local store that does carry it so be sure to check when you’re out shopping! Enjoy!
Amanda Kuhl says
I couldn’t find caramel flavor so I got hazelnut and it’s pretty tasty!
Holly says
I also love the lemon Luna Bars!!!
Cici says
This recipe looks amazing! I really don’t use the flavored syrups. What can u use instead? Also, are you asking for 4 oz chopped chocolate? If I use unsweetened chocolate instead of 90%, how much extra sweetener do you think I should add?
Mellissa Sevigny says
About one ounce of chocolate. If you omit the syrup it will change the texture and flavor, you’ll need to compensate with an extra 2 Tbsp of sweetener, an extra Tbsp cocoa powder, and use four whole eggs – even then no guarantees that they will taste like or have the texture of my recipe as written.
Rachel says
I have no no idea how you’ll make marshmallows and graham crackers…but smores, please.
Ouida Lampert says
Chocolate dipped coconut, yum!
Annie says
These sound amazing! I will definitely be making them. But what is half and half?
Mellissa Sevigny says
half and half is a product sold in the dairy case that is basically half milk and half cream. You could use light cream also if it’s what you have. Enjoy!
Anna Jados says
Oatmeal Raisin or Smores!
Sarah G says
Agree, lemon zest sounds amazing! I’m so pumped Luna bars are GF now!
Deb says
Lemon Zest is hands down my favorite Luna Bar flavor, and I would LOVE a low carb version of it because I can’t have it any more! :( I can’t wait to try making this one!
Mellissa Sevigny says
Lemon Zest is in my top three for sure Deb and it’s the one I most want to make over so I’m secretly (well not anymore, lol) hoping that will end up being the most popular flavor in the comments! Thanks for weighing in, let me know what you think of the brownies!!!
