Easy no bake keto chocolate peanut butter bars are a simple yet decadent low-carb treat. Enjoy them as a keto dessert, fat bomb, or snack. They taste just like peanut butter cup candies!
Keto Peanut Butter Chocolate Bars
Are you a lover of all things peanut butter? I certainly am. And it doesn’t get much better than the flavor of yummy peanut butter coated in chocolate.
This is a modification of a low carb peanut butter fudge recipe I used to make. Although I liked the fudge, I thought the Splenda in it made it too sweet and it was a bit plain. What it really needed was a layer of chocolate on top!
For this easy keto peanut butter cups recipe, I changed the sweetener to a mixture of monk fruit and erythritol which tones down the sweetness. I also spread melted chocolate on top.
The added layer of chocolate makes these keto peanut butter bars taste just like a Reese’s Peanut Butter Cup! Plus, I think these squares would taste amazing cut up and blended into low carb vanilla ice cream – a homemade low carb DQ Blizzard.
Easy steps for making keto peanut butter bars
- For the peanut butter layer, mix butter, collagen peptide, powdered sweetener, and peanut butter in a large bowl.
- Spread the peanut butter into a pan with parchment paper.
- Melt chocolate chips with a couple tablespoons of peanut butter.
- Smooth the chocolate layer over the peanut butter mixture.
- Place in the refrigerator to chill for at least 30 minutes.
Once chilled, the keto low carb treat is ready to cut into bars! It’s best to use a long sharp knife to cut them into even squares.
These gluten free peanut butter bars were inspired by a recipe that I learned how to make in middle school Home Economics class. That recipe mixed graham cracker crumbs into the peanut butter mixture as well as regular powdered sugar.
This version of easy to make low carb peanut butter chocolate bars brought back memories. It was so fun back in those days as a young teenager learning how to make food with friends.
In fact, I still have the handwritten note that my classmate gave me for the original bar recipe we made together in 8th grade. I loved the recipe so much, I kept it in an old Better Homes and Gardens cookbook that my mother handed down to me.
It’s great to be able to enjoy the same taste in a much healthier version of the no bake peanut butter bars. Plus, this version makes the perfect fat bombs!
Is peanut butter OK for keto diet?
Natural unsweetened peanut butter has about 4 grams of net carbs along with 16 grams of fat per 2 tablespoon serving. That makes it a low carb food that’s ideal for a ketogenic diet. However, some choose to avoid it because it often contains the mold aflatoxin.
