Not greasing the pan
How many times have you turned over a pan to release a baked good only to discover that it refused to come out? You quickly realize that you neglected to grease the pan. If you can't get your loaf out in one piece, all of your hard work will be for naught.
Greasing your bread pan properly will relieve a lot of stress. Sugar Girl Cookies confirms that nonstick cooking spray will suffice for baking your banana bread, but you can go the extra mile. The Spruce Eats suggests using a paper towel to spread shortening, butter, or cooking oil throughout the bottom and sides of the pan. After greasing the pan, lightly dust it with flour for the best results. If you follow these instructions, your loaf will fall out of the pan after baking.
