How many bananas make 1 cup of mashed banana?

From classic banana bread to other delicacies such as banana bars, banana cake or oatmeal and banana muffins, they are the stars of the show. If you end up with larger bananas, resulting in more shredded or sliced bananas, simply save the remaining bananas for another recipe. While you won't be able to achieve the same flavor for banana bread or banana pudding, you can use a substitute in other banana desserts. Mixing in an extra banana can cause banana bread or other baked banana to become too dense or soft.
