The whoopie pie is Maine’s Official State Dessert, but the now-defunct Berwick’s Bakery in Boston (1898-1977) may have been the origin: A retired employee said that the company first started to bake whoopie pies in 1926, earlier than any other reference.

But Lancaster, Pennsylvania claims to be the originator, with an anecdotal story that the recipe originated with an [unknown] Amish housewife. As the story goes, when Amish husbands and children would find the baked treats in their lunch bags, they would shout “Whoopie!”

The whoopie pie is actually a sandwich cookie: two round, mound-shaped pieces of devil’s food chocolate cake with vanilla frosting in-between. The recipe first appears in cookbooks during the Depression, in recipe collections from several states.

As the story is variously told, Amish housewives would bake these treats and put them in their farmer husbands’ (or children’s) lunch boxes. When the lucky recipients would discover what was for dessert, they would shout “whoopie!”

Today there are dozens of flavors of cakes and fillings. There’s nothing left to do but take a bite.
