I'll be making a tiered cake for a wedding shower in a few weeks and am curious if anyone has a tried and true recipe that they know will be consistent in larger pans (12"). It is surprising how many blogs use mixes, and to be honest even though I am a bit of a homemade- cake snob I was considering going that route if it was truly the best idea. But Id rather not... I was thinking maybe a good sheet cake recipe would be a good idea? Thanks for your opinions!
