Ingredients Needed for Keto Peanut Butter Cookie Bars
Exact ingredient amounts are listed in the recipe card at the end of the post.
- Unsweetened peanut butter
- Egg
- Vanilla extract
- Swerve Brown Sugar
- Milk chocolate Lily’s chocolate chips
- Sea salt, optional for topping
For the best texture, use a smooth, unsweetened peanut butter. Since this recipe does not contain flour, the peanut butter is the main ingredient that holds everything together and gives the bars their soft, chewy structure. The egg helps bind the batter, while the vanilla extract adds warmth and depth. A keto-friendly sweetener keeps the recipe low in carbs, and the chocolate chips make each bite feel like a true dessert.
How to Make Keto Chocolate Chip Peanut Butter Bars {Quick Overview}
This is a quick overview of the process. For the full recipe with exact measurements and baking instructions, see the recipe card below.
Start by adding the peanut butter, egg, vanilla extract, and keto-friendly brown sugar sweetener to a large mixing bowl or the bowl of a stand mixer. Mix until the batter is smooth and evenly combined. The mixture will be thick, similar to a soft peanut butter cookie dough.
Next, gently fold in the chocolate chips. Stir just until they are evenly distributed throughout the dough so every bar gets plenty of chocolate flavor.
Line an 8×8 or 9×9 baking pan with parchment paper, leaving some overhang on the sides. This makes it much easier to lift the bars out of the pan after they cool. Spread the dough evenly into the prepared pan and smooth the top with a spatula or the back of a spoon.
If you enjoy a sweet-and-salty dessert, sprinkle a small amount of sea salt over the top before baking. Bake until the edges are set and the center is no longer overly soft. The bars will continue to firm up as they cool, so avoid overbaking them.
Once fully cooled, lift the bars out with the parchment paper and place them on a cutting board. Slice into 16 pieces for easy serving.
TIP: Let the bars cool completely before cutting. This helps them hold their shape and gives you cleaner slices.
Can These Be Made Without the Chocolate Chips?
Yes. If you leave out the chocolate chips, these keto peanut butter bars will taste more like classic peanut butter cookies. They will still be soft, sweet, and satisfying, with a stronger peanut butter flavor in every bite.
