How far in advance can I make Banana Bread? How do I keep it fresh? Here's the deal. I'm throwing an all-day Halloween party next Sunday. There's a lot to cook and I'd like to get some items out of the way in advance. One of the items that people snarf up is a pumpkin/applesauce spice loaf I make... which, for all intents and purposes, is akin to banana bread. So... how far in advance of the party can I make this bread and how do I store it?
