Sacher Torte -- Austria
It can be impossible to pinpoint who came up with the idea for most cakes. Not so with sacher torte, a double-layer, semisweet chocolate cake with apricot jam filling. Master baker Franz Sacher created the sacher torte in 1832 for Viennese prince Klemens von Metternich. Today, most people serve it with dark chocolate frosting and a generous dollop of whipped cream on top. It's an easy cake to make but packs a real flavor wallop.
