Mix together oat flour, banana and add-ins *until uniform. Divide batter into 4 cookies, place on a pre-greased baking sheet and bake for 10-15 minutes.
Notes
*If making reindeer cookies, add ingredients after placing cookie batter on the baking sheet.* If making raspberry chia jam thumbprint cookies, cook raspberries and chia seeds in a small saucepan on the stovetop over medium heat until thickened. Place cookies on a baking sheet, make a thumbprint in the center of each and add jam.
