When I was a kid, my favorite bakery cake was called an "atomic cake". It had three layers, chocolate, vanilla and ???, a fruit filling between two layers and (I think) banana pudding. i grew up on the south side of Chicago and have never heard of the cake since. Does anyone have a recipe, a memory, a link? it's funny how our food holds such a place in our memories, isn't it? I can even remember the cool filling and whipped cream frosting. Many thanks!
