Mix all ingredients (except cinnamon) together. Spoon onto a parchment-lined pan (a well-greased pan might work, but your cookie will probably spread out more) and smooth the top. Sprinkle with cinnamon. Bake at 350 degrees F for approximately 10-12 minutes (oat fiber), 8-9 minutes (Baking Mix) or until a toothpick comes out clean and the top is no longer sticky. For best results, let the cookie cool for five minutes before digging in. Dunk in unsweetened almond milk, if desired. Enjoy!
