I have a request for a 3 tiered cake to serve 50 people and it needs to be a square cake. 10,8, & 6 will be more cake than needed. Any other sugg.?
Depends on cake serving size, and whether the client wants a 'big' looking cake. If size isn't an issue, go with smaller tiers. If size IS an issue, suggest a fake cake tier (styro).
a 10" square will feed 50 alone.
I suggest the following
8" = 32
6" = 18
4" = 8
total servings 58
For the 4" just bake one more layer of 8" then cut it into quarters, you have two cake for a 4" tier and then two extra's for you!
Sometimes if you want more "wow" factor and the number of servings is small, use a dummy for the bottom tier and the two upper tiers as real cake!
