How to Make Keto Peanut Butter Bars

These come together quickly and smell amazing even before they set.

Step 1: Prepare the Pan

Line an 8×8-inch pan with parchment paper, leaving some overhang for easy removal.

Step 2: Make the Peanut Butter Base

In a bowl, mix together:

Peanut butter
Almond flour
Sweetener
Melted butter
Vanilla extract
Pinch of salt

Stir until smooth and thick. The texture should be dough-like but soft.

Press evenly into the prepared pan, smoothing the top with a spatula.

In a microwave-safe bowl, melt the sugar-free chocolate chips with coconut oil in 20–30 second intervals, stirring until silky smooth.

Step 4: Add the Chocolate Topping

Pour the melted chocolate over the peanut butter layer and spread evenly.

If you want a bakery-style look, gently tap the pan to smooth the surface.

Step 5: Chill

Refrigerate for at least 2–3 hours, or until firm.

Step 6: Slice and Serve

Lift out using parchment paper and cut into bars or squares.
