Okay, I know that there is a lot of controversy regarding size of sheet cakes. I am baking one this weekend for a graduation and need to make sure that it will be big enough to feed 40-50 people. In a Wilton idea book that I have, it shows that a 12 x 18" cake double layered will feed 56. My question to those of you that have made one, is this what you would do? I already have 12 x 18" - 2" high pan. Help please!!!
You need a single-layer 12" x 18" half sheet.
I use half sheet cakes (19x14) for 40-50 people, but mine are 2 layers and have filling so they are a little taller than the average half sheet or sheet cake. When I stamp it for cutting (2x2 slices) it easily has enough piees for everyone/
