Ingredients Method Notes

Ingredients
  

  • 3/4 cup creamy peanut butter
  • 1/4 cup butter
  • 1 1/2 cups almond flour
  • 1/2 cup Swerve Brown
  • 1/4 cup collagen protein powder
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1 large egg
  • 1 large egg yolk
  • 1 tsp vanilla extract
  • 1 cup sugar-free marshmallows

Method
 

  1. Preheat the oven to 3250F and line an 8×8 inch metal baking pan with parchment paper.
  2. In a large microwave-safe bowl, melt the peanut butter and butter together until smooth.
  3. In a separate bowl, whisk together almond flour, sweetener, collagen powder, baking powder, and salt. Combine with the melted peanut butter mixture, egg, egg yolk, and vanilla extract.
  4. Press two-thirds of the dough into the prepared pan. Sprinkle with marshmallows and gently press.
