I have a family recipe for a chocolate cake that everyone in the family uses.  It bakes a standard 8" round two layer cake.  However, I need to make an 11x15 because I'm going to carve a violin for my brother.  I was reading The Cake Bible and the Rose factor info and she seems to refer to her own recipes in describing how to use it.  Has anyone used this method when determine how to multiple a recipe?  I'm not sure if i can just double it and have it back up okay in a pan with a larger area.

Anyone?

Can't say I've heard of the Rose factor. It probably depends on the recipe anytime I want a 9x12 I use one and a half recipes. I would think you would be able to double your recipe for a 11x15.  how much does the cake raise in an 8" pan? Fill your 11x15 the same way 1/2 full 3/4 full etc. If you have batter left some where on this site instruction on how to freeze left overs and make cupcakes out of it when you have time. Just my thoughts
