Thaw the puff pastry dough according to the package directions and lay it flat. Use a sharp knife, pie, or pastry cutter to cut the sheets horizontally into 12 equal strips a little less than a half-inch wide.

Cut the tops and bottoms off your apples and then slice them horizontally into half-inch thick rings. Depending on the size of your apples, you should be able to get about 3-4 rings out of each apple.

Use a small biscuit cutter or apple corer to punch a hole in the center of each apple slice. If you use an apple corer, you might have to enlarge the hole a bit.

Thread each apple ring with a strip of puff pastry dough, looping it around to cover the apple completely.

Transfer your apple ring pastries to a large baking sheet, and then brush the tops with butter using a pastry brush. Whisk together the sugar and cinnamon and lightly sprinkle it over the tops.

Bake the apple pastries for about 15 minutes or until golden brown. Serve immediately while still warm, and enjoy!
