The whoopie pie would probably be Maine’s state- John C.L. Morgan
dessert, if the state had one. The filling is generally of one of two types: a
thick, sweet frosting made from Crisco shortening combined with confectioners’
sugar, or, more conveniently, a dollop of Marshmallow Fluff. The cake itself is
typically not especially sweet, and is often on the dry side, since the frosting
lends plenty of sugar and a gooey consistency, said Sandra Oliver, a food
historian and columnist in Islesboro, Me.
