In a gallon-size ziplock bag, mix together the cinnamon and sugar. Set aside.
Remove the cinnamon roll dough from the package and cut each roll into six pieces. Place the pieces in a mixing bowl and drizzle with melted butter. Stir to coat.
Add half of the cinnamon roll pieces to the ziplock bag and shake to coat with cinnamon/sugar. Repeat with the remaining pieces.
Arrange the cinnamon roll pieces in a 9x13 baking dish that has been sprayed with nonstick spray. Sprinkle the leftover cinnamon sugar over the top of the rolls. If making ahead of time, cover the dish with foil or plastic wrap and refrigerate overnight. Refrigerate the included icing as well.
Remove the casserole and icing from the refrigerator and drizzle the heavy cream over the rolls. Cut the apples in the pie filling into bite-sized pieces and drop tablespoons of filling over the cinnamon rolls. Bake at 350 degrees for 27-32 minutes.
Remove from the oven and allow to cool for 10 minutes, then drizzle with the included icing.
