This cake is a ridiculous height. There are two yellow layers and two chocolate layers inside. I contem plated freezing a layer, but I simply couldn't have two of one and one of the other, so tall cake it was.
The layers were chiffon. I used Mark Bittman's basic chiffon cake recipe. It was yellow. In the chocolate batter, I reduced the flour and added that much cocoa powder. I felt this was a good method.
The frosting is vanilla seven minute, with chocolate seven minute marbled in. It was really just going to be vanilla, but I am a frosting girl, and felt as though there wasn't enough. When I decided to make more, I figured the outside might as well match the inside.
Here it is all dressed up.
