Banana bread in disposable foil plates I am considering using a disposable foil plate to bake banana bread. Is this advisable or can it be harmful? If it is acceptable, how will I amend the temperature and cooking time versus the original 350°F, 55 minutes.
Quick breads in disposable foil is the lifeblood of bake sales across the land.

There are loaf sized foil pans you can use. The 'plate' that you mention sounds like a pie-plate, which would make a very different shape and therefore baking time.

If you use a loaf pan that looks like a regular steel or aluminun pan, then your cooking time,etc will be very similar. I would advise checking it 5 minutes earlier than you are used to, as the thin pan will allow faster energy transfer.
