When these delectable cookies came out of the oven they barely made it to the photo shoot.  My family was pulling at my arm and had to try them.  I must admit, they are delicious, not to mention, they are gluten free, contain 10 grams of protein per cookie.  These cookies are a keeper and perfect for a midday snack, a quick breakfast with a glass of milk or an after dinner treat.  At each of these times, the protein will help with muscle growth, maintenance and repair, and, along with the healthy fats, will keep your appetite at bay until your next scheduled feeding session.  You can always say “yes” to these quick and easy performance-enhancing cookies without a shred of guilt!!


Yield: 12-16 cookies

  • 2 scoops KLEAN ISOLATE (~ ½ cup)
  • ½ cup granulated sugar PLUS ~1 Tbsp of sugar for garnish prior to cooking
  • 2 Tbsp unsweetened cocoa powder
  • 1 egg
  • 1 cup peanut butter
  • ~¼ cup dark chocolate chips (or more if you love chocolate)
  • Pinch of salt for garnish prior to cooking


  1. Preheat the oven to 350°F.
  2. Line a cookie tray with parchment paper or spray lightly with cooking spray.
  3. Mix together Klean Isolate, sugar and cocoa powder in a medium-sized bowl.
  4. Spray a 1 cup measuring utensil with cooking spray so the peanut butter will slide out more easily. Fill with peanut butter. Place the peanut butter and egg in with the dry ingredients. Mix together until fully blended.
  5. Add chocolate chips and blend until equally distributed.
  6. Gather a walnut-sized amount of dough and form it into a ball. Create 16 dough balls. Place each dough ball on the cookie sheet and flatten with the palm of your hand. Use the tines of a fork to create the classic peanut butter cookie markings on the top of the cookie.
  7. Sprinkle the cookies with a scant amount of granulated sugar.
  8. Bake at 350°F for 12-14 minutes.
  9. Let the cookies cool for at least 10 minutes. This will allow the cookies to set and hold together as they have minimal binding ingredients and no gluten.
