Preheat the oven to 350℉. Prepare a 9x13 baking dish by spraying it with nonstick cooking spray. Set aside.
Open both the cinnamon roll cans and set both the icing container aside. Use kitchen scissors to cut each cinnamon roll into 6 pieces (cut in half, and then cut each half into 3 smaller pieces).
2 cans (17.5 oz each) refrigerated Grands Cinnamon Rolls w/ icing
Spread the cut-up cinnamon roll pieces evenly into the bottom of your prepared baking dish.
Spoon the cherry pie filling over the cinnamon rolls, dropping dollops evenly across the top of the rolls so you get cherry in every bite.
1 can (21 oz) cherry pie filling
Sprinkle the pecans evenly over top.
1/4 cup chopped pecans
Bake for 25-35 minutes, or until the cinnamon rolls are fully cooked through and golden brown.
Let the cinnamon roll casserole cool for a few minutes, and then drizzle the icing (set aside from earlier) over the top using a piping bag, a fork, spoon, or a Ziploc bag with the corner cut.
Serve warm and enjoy!
