Banana muffins are a type of baked good that is made with ripe bananas as one of their main ingredients. They are small, round and usually have a light and fluffy texture due to the use of leavening agents such as baking powder or baking soda. Banana muffins can be sweet or savory depending on the flavorings added during preparation. Some common additions include cinnamon, nutmeg, vanilla extract and sugar, but there are many variations that can be made using different fruits, nuts, chocolate chips or spices. They are often served as a snack or breakfast item and can be stored in an airtight container for several days if kept at room temperature.
