I am wondering if someone can tell me what the best way is to make a cross cake out of either a 9X13 or an 11X15, and how much each cake would serve after it is shaped.
Would it be better to piece it together or just cut it out in one piece?

Also, any info on how much to charge would be great!
Thanks!

Cut yourself a paper pattern to size and use it to guide your cutting.
It's hard to tell you how many servings untill you know the exact size your final cake will be.....I'm guessing about 1/2 of what each of those size cakes would serve.

the template (pick one: troll / elf / gnome / wombat ) strikes again.

example cake (two full layers thick): http://www.cakecentral.com/cake-photo_568153.html

servings -- same as the sheet cake it was made from. -- only waste is the crumbs from the cut.

Perfect! Thank you very much!
