Banana bread in disposable foil plates
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.
