I just received an order for a cake that is to be two tier and serve eighty people. I am thinking of telling her she needs a 6" on top and I can maybe go 10" and 12" for the rest. I never made a cake for this many people before and I don't want them to run out. Are these good sizes for 80 servings? Thanks!
I'd suggest a 6" x 9" x 12" for 100 servings.
