I have done the topsy turvy cakes, but I want to do a tilted cake. The one I found does not have cut cake layers, but they are placed in a way that they are tilted and appear to be floating. Can anyone tell me what is underneath for support and how to possibly do it...Thanks!

There is a cake support system that you can get that allows you to do this. Look up stree free cake support and you will find the website.

I used styrofoam to do a topsy turvy cake - if this is the information your looking for - pm me and I'll help you. See my pix.
