How do I convert a cake recipe that's for a 9x2, 3 layered cake to a 12x2, 2 layered cake? I'm this close to just doubling it, but it doesn't seem right.

Thanks!!

You can use this chart by Wilton that talks about the number of CUPS OF BATTER needed for each size pan. Look in the column titled: Cups Batter
1 Layer, 2 in.

If you are using a box mix or doctored version of a box mix, most 18.25 oz. box mixes make about 4 1/2 to 5 cups of batter.

A 9x2 round pan takes 5.5 cups of batter, so three layers would require 5.5x3 for 16.5 cups of batter. A 12x2 round pan takes7.5 cups of batter, so two layers would require 15 cups of batter. If yournrecipe normally makes three 9 inch rounds, it should easily make two 12 inch rounds. hth

Thank you both! Great advice.

i use this formula

it looks complicated but once you have done it once or twice it is very accurate. it tells you how much you times the origional recipe to suit the tin you are using. I use it all the time and is sucessful every time
