I need a sheet cake to serve apx. 100 people. what size pan do i use? I was thinking of putting a 11 x 15 with a 9 x 13 on top stacked? would that work or is there a better way to feed that many people. The most I have ever had to serve is 35. Thanks

When cut in standard serving sizes of 2x2x2, a 12x18 serves 54 so two of these side by side would serve 108.

An 11x15, when cut in 2x2's, serves 35, so you'd need 3 of these to serve 100.

thanks. do they make cake boxes that big to fit two 11 x 15's?

Remember you'll need a full sheet size board too...you won't find those at HL or Michaels either.
