Preheat oven to 350 degrees. Spray a 9x13 pan with cooking spray.
Cut the cinnamon roll dough into quarters. I had 15 cinnamon rolls from the refrigerated dough I used making 60 pieces total. Add the cinnamon roll pieces to your prepared pan, set aside.
In a large saute pan, add butter and place over medium-high heat. Once butter has melted add chopped apples, sugar, and cinnamon. Cook over medium heat until apples are tender. Cooking time will vary, but it took about 7 minutes for my apples to get tender. Once apples are cooked add on top of the cinnamon rolls chunks in the pan.
Place in oven and bake for 35-40 minutes or until cinnamon rolls are completely baked up and top is slightly crispy.
Cream together the cream cheese and the butter until smooth.
Stir in the powdered sugar and 1 tablespoon of milk and whip until smooth. Add more milk and little at a time to get the consistency you desire.
Drizzle over Apple Pie Cinnamon Roll Bake and top with chopped pecans or walnuts. Serve immediately or store at room temperature until ready to serve.
If you are making this a day before, just wait to add the frosting until you are ready to serve. Frosting needs to be stored in the refrigerator, cinnamon roll bake can be stored at room temperature.
