The best keto lemon bars! These sweet and tangy lemon bars are low carb, gluten free and keto approved! Only 2.4 net carbs per square!
When my husband and I got married we didn’t have a traditional vanilla or chocolate wedding cake. We had a delicious tangy lemon cake, it is one of our favorite flavors and I am always working on new lemon desserts.
I tried a ton of other keto lemon bar recipes and none of them were quite right. Some had great flavor but the filling was too runny. Others had a great texture, but the flavor was not right. So after many attempts, I present to you the best keto lemon bars!
Ingredients for Keto Lemon Bars
You only need six simple ingredients to make these low carb lemon bars! The ingredients needed are:
- Almond Flour
- Coconut Flour
- Eggs
- Keto Friendly Sweetener (I highly recommend Swerve)
- Lemons
- Butter
How to Make Keto Lemon Bars
These low-carb, gluten free lemon bars are a breeze to make! Here’s an overview of the process:
- To make the almond flour shortbread crust, combine melted butter, almond flour and swerve sweetener. A thick dough will form.
- Press the dough into the bottom of an 8×8-inch baking dish.
- Pre-bake the crust for 7 minutes at 350F and set it aside to cool
- To make the lemon filling, combine the eggs, coconut flour, swerve sweetener, lemon juice and lemon zest in a blender or food processor. Blend until smooth.
- Chill the mixture for 20 minutes and allow it to thicken.
- When the crust has cooled and the filling has chilled, carefully pour the filling over the crust.
- Bake 18-20 minutes until the bars are set.
- Allow them to cool completely before slicing.
How Many Carbs Are in Keto Lemon Bars?
These healthy lemon bars come in at just 2.4 net carbs per square if you slice them into 9 equal servings.
How to Store Lemon Bars
These low-carb lemon bars will last up to five days in the fridge. Store them in an airtight container!
Can You Freeze Lemon Bars?
Yes! These bars freeze beautifully. They can be frozen for up to three months. When ready to eat, thaw overnight in the fridge.
Tips for Making Healthy Lemon Bars
- I recommend using swerve sweetener to make this recipe. I prefer using swerve confectioners, but granulated will work too.
- I don’t recommend substituting the coconut or almond flour in this recipe. These are the best grain-free flours I’ve tried in these bars!
- This is a great recipe to make a day or two you plan on serving it. Lemon bars keep nicely in the fridge.

Lavonne Sylvester says
There are no instructions for steps 4 and 10. Is that just an error?
Annie Holmes says
Hi Lavonne, yes it seems it just numbered the spaces I left to break up the different steps. I fixed it. I hope you enjoy, we LOVE these! 🙂
Beth Mahoney says
These are really delicious! I know my non-keto friends and family even won’t know they are keto. I found your recipe through a link on a YouTube channel called High-Falutin Low Carb. They pitted this recipe against another that had higher net carbs and he said both were winners. I chose to make your recipe because of the lower net carbs and it looked easy. I’m so glad I did. This recipe is definitely a keeper.

These were great! I saw the recipe from Wesley’s Highfalutin’ Low Carb battle. Boy he wasn’t joking. These taste SO good. I did not have Swerve confectioners sugar but regular Swerve was fine. If I do it again I will definitively use confectioners as I can sense a bit of graininess but they still taste amazing. My crust did not come out brown on the sides but it made no difference in the taste in the end. Thanks for an amazing recipe!

Can you just use coconut flour, inlace of the almond flour?
Annie Holmes says
I can only recommend the recipe as written.
