12 inch Square Wedding Cake
Delia's Classic Christmas cake recipe.
I've made this cake many times in various sizes, all very successfully, however, I've now been asked to make a 12" square wedding cake, which I have never made. Your recipe conversion chart only goes up to 10". As it is such an important cake can you upscale the ingredients for me or tell me the percentage increase I need from Delia's original recipe in her Christmas book.
Thank you in advance :)
