Bake for longer: If the center of your banana bread is still gooey, you may need to bake it for a longer time. Check the bread every 5-10 minutes by inserting a toothpick into the center. If it comes out with moist crumbs, continue baking until the toothpick comes out clean or with a few dry crumbs.

Cool completely on rack. Wrap and store at room temperature overnight before slicing. (We know it's hard to wait, but your bread will be more evenly moist and less crumbly if you let it sit overnight.)

Once a loaf of banana bread is fully baked and taken out of the oven, it's crucial to allow it to fully cool. Banana bread retains heat, especially in the center of the loaf. If the loaf is still warm once it's wrapped for storage, condensation can form, which can lead to mold.
