Directions:
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt. Set aside.
In a large bowl, beat the butter, granulated sugar, and brown sugar together until light and fluffy.
Add the egg and vanilla extract, then mix in the mashed banana until combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the oats, walnuts, and chocolate chips, if using.
Drop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes, or until the edges are lightly golden. Let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
