I am starting a cake business and I am in the process of figuring out the menu and recipes to use. I have mostly scratch recipes but use the WASC cake recipe, because I can't find a white cake recipe I like. My question is...is it ok to use this or should it be from scratch? I feel kind "funny" using a boxed cake. How about icing? Do a lot of businesses buy icing in bulk? Or make it all yourself? Thanks for any info.
