I was just Googling for a recipe almost like this. It was on the back of a Duncan Hines or Betty Crocker cake mix box and it was years ago that I made it. I seem to remember it being a chocolate mix and somehow the cheesecake part was marbled with the chocolat somehow. I took the resulting cake to a get together and everybody loved it but I never made it again and lost the recipe thinking it would be on the box again. Can you help with this?
