Hello all,

I have a customer who wants a sheet cake to serve 30, with generous size pieces. They also want the cake to be half chocolate and half lemon. Could anyone please help suggest what size cake I should make. Thanks in advance for any help.

An 11" x 15" sheet cake would give you over 30 generous-sized servings. A 9" x 13" would be too small. If you're wondering about how many servings you can get from a cake or what size cake you should make for X number of servings, here's a link to metria's cake caculator, which has been invaluable to me (thanks again, metria!):

I guess perhaps I should clarify....I agree the 11x15" would be good however, how would I bake a cake given that they want 2 flavors?

Could I bake two 8" squares and put them together? Would that be adequate?

Thanks.

You could bake 2 cakes and just push them together and ice them as one cake. You can also pour 2 different batters into the same pan. You can either start pouring both batters at the same time starting in the middle or you can cut a piece of cake board to make a divider in the middle of the pan. Pour the batter in each side and then remove the divider to bake. You may get a little mixing in the middle where they meet but not much.

Just put both of your flavors in one pan (the 11x15) the will meld a little in the middle but it's fine. This is how i bake all of my half and half cakes.

Thanks everyone! Thats perfect.

First of all, you may want to ask them how 'generous' are they thinking the pieces need to be...because most of the charts are for smaller, wedding sized pieces...Have you thought of making two 9 x 13 cakes? You can then put them together and have what is needed. For a generous piece of cake, I would bake the cakes that way.
