Recipe: Chocolate & Peanut Butter Protein Cookies

Chocolate and peanut butter cookie batter being mixed in a bowl.

Chocolate chip peanut butter cookies are a classic for a reason, and this recipe puts a high-protein twist on this firm favorite.

These gluten-free cookies each contain 10g of protein, thanks to the addition of Klean Isolate Whey Protein Powder, which is rich in essential amino acids to help fuel your foundation. Our chocolate and peanut butter cookies also contain healthy fats, creating a nutritionally balanced treat.‡

Enjoy as a mid-afternoon snack with the infamous slump hits, indulge after dinner or an intense workout, or even serve these as a high-protein breakfast option with a glass of milk.

  • 2 scoops Klean Isolate Whey Protein Powder (Unflavored)
  • ½ cup granulated sugar
  • 2 tbsp unsweetened cocoa powder
  • 1 egg
  • 1 cup peanut butter
  • ¼ cup dark chocolate chips
  • Optional: 1 tbsp sugar and a pinch of salt for garnish when serving

  • In a medium-sized bowl, mix the protein powder, granulated sugar, and cocoa powder.
  • Add the peanut butter and egg, mixing until fully combined.
  • Stir in the chocolate chips – aim for an even distribution throughout the cookie dough.
  • Use your hands to form the cookie dough into walnut-sized balls. Aim for 16, placing each one on the lined baking tray, flattening each with the palm of your hand.
