I need to make a 1/2 sheet cake and forget how many batches of WASC I need. Is there something out there of how much batter is needed for certain sized pans? Thanks!
15 cups of batter.
I make the 2 box version of WASC for my 1/2 sheet. I am switching to Duncan Hines though, as it yields more batter. I do not get the desired height from Pillsbury.
