Preheat your oven to 350F.
Mash up the bananas until they are smooth. Then add the oat flour, brown sugar, cinnamon, baking powder, baking soda, salt, and mix until well combined.
Add in your chocolate chips and mix well. Use a wet hand (because this dough will be soft!) to shape your cookies into balls. This will make 7-8 large cookies.
Tip! Cookies like this don’t spread in the oven, so make sure to form them how you want them to look when they are out of the oven!
Bake for 12-14 minutes at 350F.
Serve warm!
