Using a mandoline or a sharp knife, carefully cut apples into very thin slices. Discard any seeds. Arrange on a baking sheet prepared with parchment paper. Do not overlap apple slices.
Preheat oven to 200°F degrees.
Mix cinnamon and sugar together in a small bowl. Sprinkle cinnamon sugar mixture over apples.
Bake for 1 hour. Using tongs, gently lift apple slices to release from parchment paper. Return to oven to bake for another 1-2 hours or until no longer moist.
