Storage instructions: Banana bread will stay super moist and soft for up to 5 days or longer in an airtight container. The glaze may start to "sweat" if stored in container for 2 days or longer. It still tastes the same, just doesn't look as pretty. If this does happen, just swirl it around with a knife. My suggestion if you are making this ahead of time for another day, make the glaze fresh on the day you are going to serve the bread. Enjoy!
