More like a cake than a pie or a cookie, whoopie pies are one of Maine's best known and most loved comfort foods (sometimes made with Maine's state soft drink). The recipe for whoopie pie originated with the Amish in Lancaster County, Pennsylvania, but this popular treat has been baked in Maine since 1925.
