Classic Whoopie Pie vs Frankfurter Kranz (Frankfurt Crown Cake)

Both desserts lean on butter, milk, egg and powdered sugar, but they put them to quite different uses. The Whoopie Pie uses a single egg in a cocoa batter dropped by the spoonful and baked into rounds, which are then sandwiched with a fluffy filling of butter, shortening, powdered sugar and vanilla. The Frankfurter Kranz beats six eggs into a buttery ring cake, slices it into three layers and stacks them with jam and silky buttercream. A caramelized almond brittle coating adds crunch, while glacé cherries provide a sweet finishing decoration.
