My friends were getting married, and I provided cake as my gift. I made one presentation cake, which was apple and caramel, and this second one, which was chocolate and vanilla. I cleverly arranged it, though, so that it was half vanilla and half chocolate vertically, and then frosted it half chocolate and half vanilla horizontally. This way, people could have chocolate cake with either vanilla or chocolate frosting, and vanilla cake with either chocolate or vanilla frosting. The head caterer for the event later told me it was the cleverest thing he'd ever seen.
