Preheat oven to 400 degrees. Grease a baking tray with cooking spray

Slice apple very thin, about ⅛ inch thick. Place apples on the greased baking tray and then spray them with cooking spray

Sprinkle evenly with half of the cinnamon sugar mixture. Flip apples over then spray again with cooking spray and sprinkle the other side with cinnamon and sugar

Bake for 30-35 minutes, (flipping every ten minutes) until almost dry and edges are curled - Do not over cook!! Apples will burn easily!!

hey will not be crisp right away, let stand for 5-10 minutes and only cook until apples feel almost dry and the edges are curled up
