Notes
I use my mini food processor to puree up my banana but you can also use a fork. I don't like chunks of banana in my banana bread so I like a well smashed banana!
Mix up the ingredients by hand in a bowl instead of using a mixer. It's easier with this smaller amount of batter and you don't overmix it.
