Keto Peanut Butter Cheesecake Bars Recipe

I hear you readers loud and clear, you all LOVE these Keto Chocolate Chip Cheesecake Bars! The reviews show you all love those as much as I did, so I had to share this delicious peanut butter chocolate version, too. I kept the same tasty almond flour crust, made the cheesecake filling extra creamy and loaded with peanut butter, then topped it with a rich and chocolatey layer for good measure. You will love these for holidays, special occasions, and sweet tooth cravings.

Why you will love this keto dessert

Easy – Beginner cooks, you have nothing to worry about here! These three layers come together without any complicated techniques or unusual tools.
Diet Friendly – These bars are low-carb, keto-friendly, and gluten-free. Each bar has 6 net carbs.
Great for Making Ahead of Time – These store well in the fridge up to a week, so you can make them when you have time and serve them at your next party! You can also freeze them for long-term meal prepping.

Ingredients for Keto Cheesecake Bars

Almond flour – This keeps it low-carb, keto-friendly, and gluten-free. I do not recommend any substitutes.
Butter – This goes in both the crust and the chocolate topping. I have not tried any substitutes, but I do imagine commercial dairy-free butter would work, too.
Sweetener – We prefer this with Confectioners Monkfruit Sweetener, but Swerve Monkfruit Sweetener works, too. If you are not low-carb, you can use sugar.
Vanilla Extract – This balances and deepens the flavor.
Peanut Butter – Feel free to use another nut butter if you prefer! Almond butter would be delicious.
Cream Cheese – For the cheesecake layer. I have not used a substitute, but you could probably use a commercial dairy-free version if you have one you like.
Egg – This keeps the filling together, and I do not recommend leaving this out. You may be able to use a commercial substitute if you are egg-free.
Lily’s Sugar Free Chocolate Chips – I used dark chocolate, but you could use their milk chocolate, semi-sweet, or even white chocolate versions if you prefer! If you are not keto, you could use regular chocolate chips.

How to Make the Best Keto Cheesecake Bars

These are so easy to make. The first thing you will need to do is line an 8×8 baking pan with foil or parchment paper. This makes clean up and removing the bars for cutting much easier.

Make the crust – Combine the melted butter, almond flour, and sweetener in a bowl. Press the dough into the bottom of the lined pan and bake for 7 minutes at 350 degrees F. Allow it to cool completely before moving forward.
Make the cheesecake filling – Combine the cream cheese, peanut butter, sweetener, extract, and egg in a bowl with an electric mixer. Once the crust has cooled completely, carefully spread this cheesecake mixture over it. Bake for 30 minutes and allow it to cool completely.
Add the chocolate topping – Mix together the melted butter and chocolate chips until smooth. Pour evenly over the cooled cheesecake bars, tipping the dish back and forth so that is spreads over the entire dessert. Chill at least two hours before slicing and serving.

Tips for the Best Peanut Butter Cheesecake Bars

This recipe uses an 8×8 pan, be careful to use the correct size or your bars will be quite thin and you may not have enough chocolate topping.
The crust is very buttery, some consider this hard to work with. Just do your best to press it in the bottom of the pan. When baked the crust is a delicious buttery shortbread that is totally irresistible.
You MUST allow the crust to cool completely before adding the cheesecake.
If you find the Lily’s chocolate too dark for your tastes you can stir in 1 tablespoon of confectioners sweetener to the melted chocolate mixture.
If you accidentally heat the chocolate too fast or too long and it seems overcooked add 1 tablespoon of coconut oil or butter at a time, stir well and the chocolate will loosen up again.

How many carbs are in each keto peanut butter bar?

When cut into 12 equal sections there are 6 net carbs per bar. That is a rather large serving size, I actually prefer to cut these into 24 sections making it just right to satisfy my sweet tooth for about 3 net carbs.
