Preheat oven to 350 degrees. Prepare a baking sheet lined with parchment paper.
In a medium bowl, combine oats, almond flour, and baking powder. Stir to combine; then add cinnamon, and nutmeg. Stir until combined.
In a small bowl, add melted coconut oil, then the banana. Mash the banana using a potato masher or fork. Then add the coconut sugar and stir until combined. Fold in the chocolate chips in a scooping motion until evenly distributed.
Add the wet mix to the dry mix in the medium bowl and stir together until combined.
Cover the bowl loosely with a towel and put in the fridge for at least 30 minutes to chill (this is a good time to do dishes). =)
When ready, drop the cookie batter 1 1/2 tablespoons per cookie onto the parchment paper. I like using this cookie scooper, but you can also use a spoon and your hands. Bake 15-17 minutes or until edges and bottoms are browned; they will still be a little soft in the center. Let cool for 15 minutes to firm up a bit before eating.
Makes 12 cookies. They will last up to a week in the fridge in an airtight container.
