Preheat the oven to 375˚F.
Chop cinnamon rolls into 6-8 pieces each. Chop apples into small bite sized pieces.
Place the cinnamon rolls, apples, melted butter, sugar and cinnamon in a bowl and mix them until everything is combined and the cinnamon rolls are coated in the apple mixture.
Spray a large casserole dish with cooking spray and then pour the cinnamon rolls and apples into the dish and place in the middle rack of the oven and bake for 40-50 minutes or until cooked through.
Drizzle the glaze from the cinnamon rolls over the top of the casserole. Serve warm and enjoy!
I usually only drizzle the glaze from one package of the cinnamon rolls. You can use both, or one, whichever you prefer.
