Notes
Mix the ingredients just until they are combined. Overmixing can produce a denser texture, so be gentle when folding in your dry ingredients.
To check for doneness, insert a toothpick into the center of the banana bread. If it comes out clean or with a few moist crumbs, it's ready.
Let your banana bread cool in the pan for 10-15 minutes before transferring it to a wire rack. This prevents it from becoming too moist due to trapped steam.
