History / Background
Whoopie pies originated in the United States, with both Pennsylvania and Maine claiming the creation. According to folklore, Amish wives would pack leftover cake batter into lunchboxes, shaping them into hand-held cakes. When farmers found them, they shouted, “Whoopie!”—and the name stuck.
Over time, whoopie pies became beloved across New England and Pennsylvania Dutch communities. Traditionally made with chocolate cakes and marshmallow filling, they evolved into different flavors, sizes, and fillings. Today, whoopie pies are an iconic American treat and are often enjoyed at fairs, bakeries, and family gatherings.
