1Preheat your oven to 350°F (175°C).
In a large bowl, mash the ripe bananas until smooth.
Add the rolled oats, dark chocolate chips, and vanilla extract to the mashed bananas. Mix until well combined.
Drop spoonfuls of the mixture onto a baking sheet lined with parchment paper.
Flatten each spoonful slightly with the back of the spoon.
Bake in the preheated oven for 12-15 minutes, or until the cookies are golden brown.
Remove from the oven and let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Enjoy your Banana Oat Cookies!
