Ah, okay.Cakes are done by Disney pastry/bakery, who makes all the specialty cakes that anyone can order. The projection cakes are artificial with a substantial up charge for each tier requested to be real cake. It's really just a fancy prop, not food.
My understanding of these parts of the compay is pretty limited.
I recall seeing them presented together in a single booth at a Disneyana convention but that was at least... um... Well, I'd rather not say but you can get an idea by how long ago the last Disneyana convention was, I guess.
