Step 1

Preheat oven to 225°. Core apples and cut crosswise into 1/8-in. slices. In a shallow bowl, mix sugar and cinnamon. Dip apple slices in sugar mixture to coat both sides; shake off excess. Arrange in a single layer on parchment-lined baking sheets.

Step 2

Bake 1-1/2 hours. Turn; bake 50-60 minutes longer or until apples are dry and slightly shriveled. Remove from pans to wire racks to cool completely.

Step 3

In top of a double boiler or a metal bowl over simmering water, melt chocolate; stir until smooth. Dip apple slices in chocolate; allow excess to drip off. Place on parchment or waxed paper; decorate with sprinkles as desired. Let stand until set. Store in airtight containers.
