Simple, tasty peanut butter cookies packed with protein. So full of peanut butter flavor, they will practically melt in your mouth! These cookies will not turn out cake-like due to the whey protein. As a matter of fact, many of the people I serve these to either can't tell the difference, or prefer these over other versions of peanut butter cookies!

  • Combine peanut butter, egg, and vanilla extract in a bowl with a fork. Mix until smooth. Add sugar, whey protein, and salt. Mix well until ingredients are blended together.

  • Scoop the mixture out with a tablespoon and roll into 3/4-inch balls. Place onto ungreased baking sheets, about 1/2 inch apart. Flatten each cookie to 1/4-inch thickness with a fork.

  • Bake in the preheated oven until golden brown on the edges, about 6 minutes. Let cool for at least 3 minutes before transferring to a wire rack to cool completely.

Cook's Notes:

You can use any sweetener you like.

If you are using plain whey powder, consider adding vanilla extract to make up for the missing flavor.

If you attempt to remove the cookies before they have cooled, they will crumble!

Quick and easy to make. I had to use my hands to make the dough come together and I only got 18 cookies (not 36) from the full recipe. I used a small cookie scoop and then rolled them into balls. They are reminiscent of a peanut butter cookie. Thanks for sharing your recipe. Read More
