I have gotten a sheet cake birthday order. I very rarely do sheet cakes for others so I am concerned about 1. size on top and 2. height. She only needs to feed 15-20 and wants an animal along with Happy Birthday and the child's name. So I am debating doing a double layer 7 x11 or single layer 9 x13. The 9 x 13 will give me more decorating room but would only end up being 2 or 2 1/2 inches high, while I could do a 4 inch 7 x 11. What do you think?
The Wilton guide for party sizes shows that a 7x11x4 serves 28, an 11x13x2 would serve 23.
If she's willing to pay for the extra servings, I'd do the 11x13x2 because of the extra room on the top for decoration.
FYI, I split & fill all of my cakes, including 2" tall sheets.
What do you think?
I think a 9x13 is more than enough.
I also split and fill my cakes--it's pretty easy with a bread knife. That would give you more of the height you're looking for.
Thanks for the advice guys, I think I'll do the 9 x 13 and split n fill Now I feel better about it
