Yesterday I made a Chocolate Peppermint cake which is basically a light chocolate cake with a pepermint creme layer then chocolate icing on top. The problem is that the amount of peppermint creme the recipe calls for is about twice as much as you need. It actually made the cake 'sink' in the middle from the weight, but I didn't notice that till it was cut, so now there's a massive wedge of the creme which makes for a very rich cake.
Lucky it tastes nice.
