Preheat oven to 400 degrees F.
Prepare dumpling pastry. Roll the pastry into a rectangle, 10 by 8 inches. Cut into 4 (4-inch squares) with pastry cutter or knife. Place apple on each square. Spoon 1 tablespoon brown sugar and 1 teaspoon cinnamon into the center of each apple. Moisten corners, pinching edges of pastry to seal. Brush with slightly beaten egg and sprinkle with additional sugar. Bake 30 minutes or until crust is golden and apples are tender.
