Ok, so I've seen many of the pregnant belly cakes and I LOVE THEM and have just been asked to do one. I've seen several posts about making them, and just want to run this past all of the fabulous decorators here

This cake needs to feed 50-60 people, they only want the belly, no sheet cake underneath. should I just make a 12 inch round and let it "dome" while cooking? any other thoughts/ideas/tips/suggestions?

**YOU** are the decorator/designer.
Don't let them tell you how to create it.
I don't think it will look good at all unless there is somesort of 'base' cake under it.
I would put it on a 16" round.

I agree with kakeladi!

I did one with a sheet cake underneath, which supported the design, but it's not obvious that it's there.

Here's the cake:

Here's what the cakes looked like "nekkid":

Hope this helps!!

Have they seen any with a sheet or other type cake underneath? Maybe they are just having difficulty picturing it. I think that would be the only way to get enough servings unless you complimented it with cupcakes or something.
