Allow the banana bread to cool in the loaf pan for 15 minutes. Next, gently run a knife along the inside of the pan to help release the loaf. Carefully transfer it onto a wire rack. Let the loaf rest on the cooling rack until it cools down, making it easier to handle and allowing it to set slightly before you slice it.
