Dive into the wonderful world of flavor with these Banana Oatmeal Cookies.
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a bowl, mash the ripe bananas with a fork until smooth.
In a separate mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until well combined.
Beat in the egg and vanilla extract until the mixture is creamy and smooth.
In another bowl, whisk together the old-fashioned oats, all-purpose flour, baking soda, salt, and ground cinnamon if you're using it.
