Notes
If your bananas are really ripe you won't have to mash them, just squeeze them out of the skin directly into the batter. If they are a littler firmer you can mash them by placing them in a bowl and use your hand mixer to beat them until the desired consistency. If you want chunks of banana in your bread don't beat it as much and leave it somewhat chunky. Beat it smooth if you don't want chunks of banana in your bread.Add in 1 cup chocolate chips or nuts for a fun flavor variation. You can also add in 1 tsp of cinnamon if you like.
