Preheat oven to 350° F. Lightly grease a baking sheet with coconut oil.
In a medium bowl combine the almond flour, oat fiber, arrowroot starch, baking soda and salt.
In another medium bowl combine the egg, vanilla, syrup and (cooled) oil. Add the wet ingredients to the dry ones and mix until fully combined. Stir in the mini chocolate chips.
Shape the dough into 18 cookies, flattening them slightly onto the greased pan. Bake for 8-11 minutes, or until golden.
Allow to cool on the pan for 5 minutes, then transfer to a wire cooling rack. Store in an airtight container in the fridge.
