How do I do it?
Preheat oven to 225-degree F (110-degree C)
Slice apples and arrange slices on a metal baking sheet
Mix sugar and cinnamon on a bowl and sprinkle apples
Bake in the preheated until apples are dried and edges curl up, 45 minutes to 1 hour. Transfer apple chips, using a metal spatula, to a wire rack until cooled and crispy.
