When Stored in the Refrigerator, Banana Bread will Become Dry.
It is important to remember to remove banana bread from the refrigerator and instead store it at room temperature. Due to the high moisture content and low temperatures, banana bread will dry out in the same way that bread does. If the texture of dry banana bread isn’t to your liking, you won’t eat it.
The same is true for a wide variety of other sweets as well. The moisture in the bread will evaporate when it is exposed to the cool air in the refrigerator, but it will stay fresh for up to four days on the counter.
