My brother has asked that I do his wedding cake as a gift to him (yikes, I offered to just pay for his cake but he wants ME to actually DO it), and I'm struggling a little bit trying to figure out what size pans to get. It's a square cake and I need enough to feed 100 people, and I'd like to preserve the top layer as an anniversary layer. I looked up cake servings and if I do a 10, an 8 and a 6 (anniversary), that leaves me short. If I do a 12, 10 and 8, that gives me way too much, and a huge anniversary layer. Should I do 12, 8 and 4? Help me figure this out, I'm sure there's a great solution but I'm probably just not thinking of it cause I'm stinking nervous about doing this cake!

I would use a 12 (72) a 9 (36 with alittle extra) and a 6. this way you have 108 servings and the 6 for their 1st anniversary.
