I have attached a photo of my oven with two disposable cake pans side by side init, as well as a pic of the disposable next to a real cake pan. The disposable is about one inche shorter , half an inch narrower and half an inch less deep than the real one. I need to make 16 of the disposable pan cakes over the next couple of days. I am guessing i will use half a cup less batter. What does wisdom say about putting two in the oven side by side?
