Preheat your oven to 375°. Line two baking trays with parchment paper and set aside.
Place the oats, coconut flour, rice flour and baking soda in your food processor.
Process until the oats are ground up fairly finely, a little coarser than regular flour.
Add the coconut oil, brown sugar, aquafaba, and cinnamon and process until it forms a sticky dough.
Add the marshmallows and pulse a few times, making sure you can still see big chunks of white marshmallow.
Add the chocolate chips and pulse a few more times just to incorporate.
Place the dough in rounded tablespoons onto your prepared baking sheet.
Bake for 10 minutes and remove from oven.
Cookies will still be VERY soft. Let them cool on the baking sheet for about 10 minutes—they will firm up but still be soft and chewy—and then transfer to a cooling rack to finish cooling. Enjoy!
