Preheat oven to 350 degrees F. Put either a silicone baking mat or some parchment paper on a cookie sheet.
In a large bowl, mix the rolled oats, almond flour, salt, and baking soda together with a fork.
In another bowl, mix the vanilla, egg, coconut sugar and mashed banana together with a fork until well mixed. Add the melted coconut oil and mix again.
Pour the bowl of dry ingredients into the bowl of wet ingredients and mix until fully blended.
Mix in chocolate chips. Then scoop spoonfuls of the dough and place them onto the cookie sheet. I scooped a heaping Tablespoon full of the dough to make each cookie.
Bake for 10 minutes, then let the cookies rest on the pan for 2 minutes. Remove and place the cookies on a cooling rack.
