Position an oven rack in the center and preheat your oven to 375F degrees. Line a baking sheet with parchment or wax paper.
In a mixing bowl, combine the flour, oats, baking powder, baking soda, salt and sugar until well blended and set aside.
In another bowl, combine the oil, milk, banana puree and vanilla.
Stir the flour mixture and banana mixture together just until moistened.
Make 10 cookies from the batter, spacing them at least one inch apart on the cookie sheet. Flatten them out with damp fingers, since they will not spread as they bake.
Bake on the center rack for 10 to 12 minutes, until they look done and spring back when gently pressed with your finger.
Remove from the oven and immediately transfer to a wire rack to cool completely.

I'm sure rice milk or almond milk would work too, but I'm a big fan of coconut milk at the moment.The recipe calls for oat flour. You can make oat flour by pulsing rolled oats in your blender or food processor until it's the consistency of flour.To lower the points for these cookies, substitute your favorite zero calorie brown sweetener for the sugar - I like Truvia Sweet Complete Brown, Swerve Brown and Lankato Brown Monk Fruit Sweetener.
