Preheat your oven to the temperature specified by your cinnamon roll recipe (usually 350°F to 375°F). Lightly spray a 9x13-inch baking dish with non-stick spray.
Pour the melted butter evenly over the bottom of the baking dish.
Sprinkle the packed brown sugar in a thick, even layer over the melted butter.
Pat the drained pineapple rings and cherries completely dry with a paper towel.
Arrange the pineapple rings in a single layer over the brown sugar. Place one cherry into the center hole of each pineapple ring.
Place one unbaked cinnamon roll directly on top of each pineapple ring.
If using homemade dough, cover and let proof until doubled in size. If using canned dough, proceed immediately to baking.
Bake according to your dough's recipe instructions (usually 25-30 minutes), until the dough is golden brown and cooked through.
Remove the pan from the oven and let it sit undisturbed for exactly 5 minutes.
Place a large cutting board or platter over the top of the baking dish. Using oven mitts, quickly invert the pan. Gently remove the baking dish to reveal the caramelized rolls. Serve warm!
