I have made a 12x18 cake but it is for my sons jr. high football team there are 32 boys and 3 coaches How much cake would I need???
My guess is they will cut larger than a normal serving size. So maybe make two and stack them so it's 4" tall. A 12x18x2 will serve 54 people (2x2x2 servings - industry standard) and at 4" tall it will serve 108
Is it a 1 layer cake?
If you cut it in 2x2x2 pieces you will get 54 pieces.
