Make sure all your ingredients are measured and ready before you begin. It helps the process go smoothly.
Start by creaming the butter and brown sugar together until light and fluffy. This is important for getting that perfect soft texture in your cookies.
Once the butter and sugar are combined, add in the egg, mashed bananas, and vanilla extract. Mix until smooth and well combined.
In a separate bowl, whisk the flour, baking soda, salt, cinnamon, and nutmeg until well combined.
Gradually stir the dry ingredients into the wet ingredients until just combined, don’t overmix!
Next, fold in the oats and chocolate chips, making sure they’re evenly distributed throughout the dough.
Scoop the dough onto a parchment-lined baking sheet, spacing them about 2 inches apart.
If you’d like, gently press the dough balls down for a more even bake.
Bake at 350°F (175°C) for 10-12 minutes, or until the edges are golden and the tops have set.
Let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack to finish cooling. Enjoy!
