Ingredients

Scale

Peanut Butter Protein Bars:

  • 6 1/4 scoops (53cc scoop size) (4 1/8 ounces) Vanilla Whey Protein Powder (I used Less Naked Whey)
  • 5/8 cup (2 1/2 ounces) almond flour
  • 5/8 cup (2 ounces) gluten-free rolled oats
  • 1/8 teaspoon salt
  • 1 1/4 cups (11 1/4 ounces) natural unsweetened peanut butter
  • 5 tablespoons (3 1/2 ounces) maple syrup
  • 2 1/23 tablespoons water
  • 2 teaspoons vanilla extract

Chocolate Topping:

  • 6 ounces no-sugar-added dark chocolate, chopped
  • 2 teaspoons coconut oil
  • flaky sea salt/fleur de sel (optional) 

Instructions

Peanut Butter Protein Bars:

  1. Line an 8″ square baking pan with parchment paper or foil.
  2. In the bowl of a food processor fitted with the steel blade attachment, pulse together the protein powder, almond flour, oats, and salt until the oats are broken into smaller pieces and all ingredients are evenly combined. Add the peanut butter, maple syrup, 2 1/2 tablespoons water, and vanilla extract and pulse just until the mixture comes together, stopping to wipe down the bowl with a spatula if needed. Add the remaining 1/2 tablespoon water if needed to bring everything together.
  3. Transfer the mixture to the prepared pan and press down in a flat, even layer (it helps to use a wide, flat spatula for this). Transfer to refrigerator and chill for 1 hour.

Chocolate Topping:

  1. In a small, microwave-safe mixing bowl, combine the chopped chocolate and coconut oil. Microwave for 30-second increments, stirring in between, until smoothly melted. 
  2. Pour chocolate over bars and transfer back to refrigerator until set, about 30 minutes. Once set, use parchment or foil to lift bars from pan and slice into 12 individual pieces. Sprinkle bars with sea salt or fleur de sel if desired. Store in an airtight container in the refrigerator. 

Notes

*Total time does not include chilling time.
