I'm going to be baking in shaped aluminum pan for the first time (1980 Wilton R2D2 robot from Star Wars). I am not a real cook and will definitely be using a boxed mix of some kind. I have the release spray. Can someone please tell me what kind(s) of boxed cake mixes work best? Like avoid ones that say super moist, angel food cake, etc.?
I've tried Google and have found the original instruction sheet, but not what type of mix is advisable.
