There was an Adult Advanced division, but there were only a few cakes and none of them were very interesting.
The Professional Division is for decorators with a high level of skills, more than six years cake decorating experience, and more than 90 hours of cake decorating or sugar art instruction.
There were a lot of entries, but the photos below are the ones I found interesting.
…with a discarded banana peel behind him…
It's supposed to be a birthday cake, but all I see is a clown hat. A very feminine clown hat.
I wish I had a better photo of the Blue Meanies at the bottom of the cake.
While I'm not sure I'd be willing to eat it, it was impressive… and large.
