Ingredients

Scale

Dry Ingredients

  • 1 cup protein powder (chocolate or vanilla flavor)
  • 1/4 cup unsweetened cocoa powder
  • 1/3 cup chocolate chips

Wet Ingredients

  • 1/2 cup creamy peanut butter

Instructions

  1. Mix Ingredients: In a large mixing bowl, combine the protein powder, cocoa powder, and chocolate chips. Add in the creamy peanut butter and stir thoroughly until all ingredients form a thick, uniform batter.
  2. Press into Pan: Line an 8×8 inch baking pan with parchment paper or lightly grease it. Evenly press the mixture into the pan using a spatula or your hands to create an even, compact layer.
  3. Chill Until Firm: Place the pan in the refrigerator and chill for at least 1-2 hours, or until the mixture firms up and holds together. Once set, cut into bars of desired size and enjoy.

Notes

  • For a vegan version, use plant-based protein powder and a peanut butter without added dairy.
  • Store bars in an airtight container in the refrigerator for up to one week.
  • You can customize these bars with nuts, seeds, or dried fruit for extra texture and nutrition.
  • If the mixture is too dry, add a small amount of almond milk or honey to help bind the ingredients.
