How to Make Keto Chocolate Peanut Butter Bars

Making keto chocolate peanut butter bars with chocolate layer and creamy peanut butter filling

The process is surprisingly simple and requires very little active work.

Step 1: Prepare Your Pan

Line an 8×8 inch baking dish or loaf pan with parchment paper, leaving some overhang to make removal easier later.

Step 2: Make the Peanut Butter Layer

In a mixing bowl, combine the almond flour, peanut butter, sweetener, vanilla extract, and half of the coconut oil. Stir until a thick dough forms.

Press the mixture evenly into the prepared pan to form the base layer.

Step 3: Make the Chocolate Layer

Melt the sugar free chocolate with the remaining coconut oil in a microwave-safe bowl or over a double boiler. Stir until completely smooth.

Step 4: Assemble the Bars

Pour the melted chocolate over the peanut butter layer. Use a spatula to spread it evenly across the surface.

Step 5: Chill Until Firm

Place the pan in the refrigerator for at least one hour or until fully set.

Step 6: Slice and Serve

Lift the bars out using the parchment paper and cut into squares or rectangles using a sharp knife.

You now have rich, creamy, chocolatey keto bars ready for snacking, sharing, or quietly hiding from everyone else in the house.
