Keto lemon bars are extremely easy to make and you can enjoy them year-round. These are the perfect bars for taking to any parties or potlucks.
You can also add these bars to your kid’s lunches as a special treat. They’re great for an after-work or after-school snack.
The keto lemon bars filling is bursting with lemon flavor. It’s hard to eat just one. The filling is also extra creamy because I added egg yolks. Even though the filling has coconut flour in it to help thicken it, there is no gritty texture. You can’t even tell there is coconut flour.
I used my favorite coconut flour pie crust that works great in any recipe that needs a shortbread-like crust. I use this pie crust often because it’s so versatile. For desserts, I recommend adding 3 tbsps of erythritol or monk fruit sweetener to the crust.
Keto Lemon Bars FAQ
- How can I make this recipe egg-free? I didn’t test an egg-free version but I feel you could try mixing coconut cream, lemon juice, erythritol, salt, and some gelatin together and refrigerate it until firm.
- How can I make this Paleo-friendly? You can easily make these bars Paleo-friendly by using raw honey, organic cane sugar, maple syrup, etc instead of erythritol.
- Can I substitute almond flour for coconut flour? I didn’t test an almond flour version but I have seen recipes that use almond flour in the filling. You could try ¼ cup of almond flour in the filling instead of coconut flour.
- How do I store these keto lemon bars? These keto lemon bars will last about 5 days if you store them in an airtight container in your refrigerator. You can also keep them stored in your freezer for up to 3 months.

- 6 large eggs + 2 egg yolks, at room temperature

- 1/2 cup powdered erythritol blend
- 1 tablespoon coconut flour
- 1/2 teaspoon of salt
- optional – extra powdered erythritol or swerve confectioners for dusting bars
- 1 recipe for coconut flour pie crust
- First, line an 8×8 baking dish with parchment paper and make the shortbread dough and bake it. While it is baking make the filling.
- After the crust is done, preheat the oven to 325° F.
- Add 6 eggs and 2 egg yolks to a large mixing bowl and whisk together.
- Add lemon juice, erythritol, coconut flour, and salt, and stir again to combine. Make sure the filling has been really mixed so you don’t end up with any white egg chunks after it has baked.
- Pour the filling over the baked crust. Bake at 325° F for 20-30 minutes or until the filling is just set in the center and no longer jiggles.
- Allow the bars to cool in the baking pan at room temperature for 1-2 hours. Then transfer to the refrigerator and cool for another 1-2 hours.
- To serve, lift the parchment paper out of the baking pan. Dust the bars with extra powdered erythritol. Then cut into squares. It is best to serve these bars chilled.
Note: Consider sifting the powdered erythritol before adding it to the filling to remove any clumps.
