It has finally been done: a peanut butter and jelly flavored protein shake that actually tastes like…peanut butter and jelly! Rejoice!! I have tried so many combinations and seen tons of recipes online that used the same combinations I tried and they were all decent. But, they all fell short of tasting like actual peanut butter and jelly. The answer to this dilemma was found in a most unlikely place: an art supply store.
