These banana cookies are soft and cakey. For the best flavor, use very ripe bananas. If you'd like, stir in chocolate chips or chopped nuts.
Mash banana in a small bowl. Set aside.
In a medium bowl, whisk together flour, baking powder, baking soda, cinnamon, and salt. Set aside.
In a large bowl, mix brown sugar and butter together until blended. Mixture will be thick. Add egg and vanilla extract. Beat until fluffy. Stop mixer and scrape down bottom and sides of the bowl with a rubber spatula.
Add flour mixture and mashed bananas. Mix until blended. If using, add chocolate chips or nuts, if using.
Store cookies in an airtight container for up to four days or freeze for up to two months. To freeze the cookies, place into a freezer container. If you need to stack the cookies, place a piece of parchment or wax paper between each layer.
Mixing bowls: You'll need three mixing bowls to make these cookies. A small one for mashing the bananas. A medium bowl for whisking the flour with the other dry ingredients. And a large bowl for making the batter.
Cookie Scoop: For evenly sized cookies, use a cookie scoop.
