2 large apples
Preheat oven to 200 degrees. Line 2 large jellyroll pans with parchment paper or wire racks, I used parchment paper. Core apples and peel if desired. Thinly chop apples, try to get them as thin as possible. I used a mandoline set on 1/8" and it worked great, but they could have even been thinner. Lay apples on prepared pans in a single layer. Bake about 2 hours, flipping half way. After flipping, dust lightly with cinnamon. Chips will get slightly crisper as they cool but you may have to adjust baking time depending on the thickness of your slices.
