Chocolate protein cookies sandwiched with a double chocolate protein frosting. Yes. These Double Chocolate Protein Cookies are chocolate heaven!

These high protein cookies are made with a whey/casein blend, which makes cookies firm enough to handle the rich, fudgy protein filling.

The frosting is delicious on its own, too, so I've included the macros for it alone below.

Give this deliciousness a try!
