Whoopie pies are believed to have originated with the Pennsylvania Amish community in the early 1900s. Though other regions of New England, particularly Massachusetts and Maine, claim the whoopie pie as their own, the cream-filled cake-like cookies have since become a favorite across the nation. Our bake is a supersized version of the single-serving original that’s party-ready and guaranteed to put a smile on your face.
