I want to make a real ice cream cake. When I was a kid we bought an ice cream cake. And it stayed soft in the freezer for days. The thing is, it was real cake- not the gravel type substance they are made out of these days. What I'm trying to figure out is how to make a chocolate cake that will stay soft in the freezer. Even if I have to use some sort of funky (food safe) chemical(s). Anyone have any ideas? Help would be very much appreciated.
