I need to make a stacked cake to feed about 150 people. The problem is, my oven will only accomodate a 14" round. It is a convection and a 16" won't allow the door to close all the way.

Any advice on what would look good, feed 150, and start with a 14" round bottom? Do they sell two half round pans that equal a 16"? Doubtful, huh?

They do make half rounds http://www.amazon.com/dp/B000E4C2IK/?tag=cakecentral-20 I've seen them in 18" too.

The 16" 12" 8" on this page http://www.wilton.com/cakes/tiered-cakes/serving-amounts-150-200.cfm look nicely proportioned to me.

6/8/10/14 = 150. That's what I do when I need 150 servings exactly.
