I have to make a large amount of cake, and have a 12.5x17.5.1 jellyroll pan I plan to use to make a sheet cake or 2. Has anyone ever used one of these? I need to know about how many wedding servings are in one of the cakes as a 2-layer, or how I might go about figuring it out?

Or 4. If your 17.5.1 measurement means that it's 1" deep, you'll need to bake 4 of these for a standard 4" tall layer cake.

A wedding serving is typically 1" x 2" x 4" (8 cu. in.). Since the sides of the jellyroll pan are probably flaired out near the top instead of perfectly straight-sided, you might choose to trim .25 inches off all sides which leaves you with cakes that are 12 x 17. If a 12 x 18 double-layer (4" high) cake serves 108 (it's cut 12 rows by 9 columns = 10, then a 12 x 17 layer cake (4" tall) serves 99 (cut 11 rows by 9 columns = 99). HTH!

They also sell extenders so that you can bake a 2", but I don't know why they wouldn't fit your pan by a half an inch!
