Classic Whoopie Pie vs Kirschmichel (Baked Cherry Pudding)

Both desserts lean on milk, butter, egg and powdered sugar, but put them to very different work. In the whoopie pie, butter is creamed with sugar and egg into a cocoa batter baked as cake-like rounds, which are then sandwiched with a sweet, creamy filling of powdered sugar, butter and shortening beaten with vanilla until fluffy. The Kirschmichel instead whisks milk, eggs and melted butter into a cinnamon-scented custard that soaks stale bread, which is layered around tart sour cherries and baked until golden and tender, with powdered sugar used only as a final dusting.
