I think "my" Triple Layer Brownie cake would take the prize for me. It's a recipe I got years ago from Taste of Home magazine. It has something like four eggs, a bunch of butter, 2 cups of sugar, etc., etc. When I serve it people eat just a small piece (I can eat a BIG piece, I'm sorry to say!) I tell people "If you have to ask what's in it, you shouldn't eat it." because it has loads of fat and calories. But, oh, is it delicious!!! The recipe calls for a cooked frosting, which is delicious, but takes quite a while to create, since it needs refrigeration during the process. I usually just top it with chocolate butter-cream frosting and it's every bit as yummy!
