What you need,
1 large granny smith apple, cored and sliced 1/8” thick
1 tsp. granulated sugar
1 tsp. ground cinnamon
Heat your oven to 200 degrees.
Mix the sugar and cinnamon in a large zip top bag. Add the
apple slices and shake well to coat.
Place the apples in a single layer on 2 large baking sheets
lined with parchment paper and sprayed lightly with cooking spray.
Bake the apples for 1 hour, then flip the slices over and
bake 1 hour more.
Check the apples; they should be crisp but still a little
bendy. You may need to bake them up to ½ an hour longer.
Let the apples cool completely before storing in an airtight
container.
They will last about a week if you don’t eat them all in one
sitting like I did!
