Roughly how many servings do you think a cake made with that will serve? I have a customer interseted in a cake for her daughter's birthday party with one, but they are looking at having 30 children. I don't think that will serve that many, but I've not made one before.

Thoughts? I may well just make a regular cake, stack and carve it to meet their needs, but I'm not overly good at that.

The wondermold will serve about 15...What I do is place another 8 inch layer underneath to make the dress fuller and longer.You also have to do this anyway for a standard size barbie doll as she is too tall for the wondermold itself and the skirt looks squatty and un-proportioned.I also have added another 10 inch layer under that to get more servings.
