Ingredients

Base Layer:

  • ½ cup 130g peanut butter (unsweetened, softened)
  • 1 ½ tablespoons coconut flour
  • 1 tablespoon protein powder
  • 1 ½ tablespoons granulated sweetener

Top Layer:

  • ½ cup 130g peanut butter (softened)
  • 1 tablespoon unsweetened cocoa powder
  • 1 ½ tablespoons granulated sweetener
  • 1 tablespoon protein powder
  • 1 ½ tablespoons coconut flour

Instructions
 

Preheat the Oven:

  1. Preheat the oven to 175°C (350°F). Line a small baking dish with parchment paper to prevent sticking.

Prepare the Base Layer:

  1. In a mixing bowl, combine the peanut butter, coconut flour, protein powder, and sweetener. Mix with a fork until well incorporated, then knead the mixture with your hands to form a smooth dough.

Prepare the Top Layer:

  1. In a separate bowl, mix the softened peanut butter, cocoa powder, sweetener, protein powder, and coconut flour. Stir until a thick, cohesive mixture forms.

Assemble the Layers:

  1. Spread the base layer evenly in the prepared baking dish, pressing it firmly into place. Gently spread the top layer over the base, smoothing it with a spatula to create an even surface.

Bake:

  1. Place the dish in the preheated oven and bake for 25 minutes, or until the top layer is set and slightly golden around the edges.

Cool and Slice:

  1. Remove from the oven and allow the bars to cool completely before slicing. This will ensure a firmer texture and cleaner cuts. Once cooled, slice into bars or squares as desired.

Notes

To ensure this recipe remains entirely gluten-free, use a certified gluten-free protein powder and confirm that your granulated sweetener does not contain any gluten-based additives. Coconut flour is naturally gluten-free, making it an excellent alternative to traditional flours.
