(1) I tried this in a convection oven. I do not recommend this option. 350 was MUCH too hot (top and sides cooked before middle). I turned it down to 250 and checked frequently for done-ness.
(2) I made this recipe increased twelve fold! I used 48 bananas, two dozen eggs, 3 lbs of "I can't believe its not butter", 12 cups of sugar, 6 tsp of vanilla extract, 4 TBS of baking soda, 2 TBS of salt, and a whole 5 lb bag of flour! I used five large pans and IT TURNED OUT GREAT. You need VERY LARGE BOWLS to attempt to mix this!
