Notes
This recipe calls for a combination of whey and plant proteins to give the cookies the structure needed to stand up to being filled. If you'd like to use only plant based protein, try this recipe for Chocolate Protein Cookies and use black cocoa powder instead of regular.If you'd like a recipe using only whey protein, try this recipe for Protein Whoopie Pies, and use black cocoa powder instead of regular.And if you have a whey/casein blend like Quest or PEScience protein, try this recipe for Double Chocolate Protein Cookies,and again use black cocoa powder instead of regular.
