This is a funny little recipe. It only has four ingredients and requires no baking. I used to make this cake when my boys were little and it always amazed me. I was looking through my recipes the other day for something and came upon this and had fond memories of it. I can't even remember where I got this recipe from anymore, but it's a winner.
How does a cake require no baking? It's made from chocolate graham crackers and after you've frosted the crackers and let the cake sit for several hours, they soften up and become cake-like. No kidding. It works very well. You make two frostings, one with peanut butter and one with chocolate. It's easy and a great make-ahead little cake with very little effort.
The frostings are definitely worth making from scratch. They are basically just flavored whipped cream frostings, one peanut butter and one chocolate, and they are light and fluffy and absolutely delicious.
