Preheat the oven to 350 F degrees. Grease a standard-sized bundt pan (10-12 cups) thoroughly with non-stick cooking spray or butter.
In a small bowl, mix together the granulated sugar, ground cinnamon, and nutmeg. Set this cinnamon-sugar mixture aside.
Open the cans of refrigerated cinnamon rolls and separate them. You'll have 16 individual rolls. Cut each cinnamon roll into quarters. This will give you bite-sized pieces to work with.
Roll each quartered cinnamon roll piece in the cinnamon-sugar mixture until it's well-coated. You can also do this by placing the sugar mixture in a zip-top bag and tossing the pieces in it for even coating.
Arrange the coated cinnamon roll pieces in the prepared Bundt pan, creating layers. If you'd like to add some crunch and flavor, sprinkle the chopped pecans or walnuts between the layers.
In a small bowl, mix together the melted butter, brown sugar, and maple syrup until well combined.
Pour this mixture evenly over the cinnamon roll pieces in the Bundt pan. Try to keep the sauce right on top of the cinnamon roll pieces and not let it run down the sides. Letting it run down the sides will make it difficult for the monkey bread to come out of the pan because a pool of caramel may form at the bottom.
Bake for 30-35 minutes, or until the monkey bread is golden brown and the cinnamon rolls are cooked through.
Remove the monkey bread from the oven and let it cool in the pan for about 5 minutes. This allows the caramel sauce to thicken slightly. Don’t let it cool much longer than 5 minutes, or it will be too hard to remove from the pan.
Put the icing in a microwave safe bowl and heat for 10-15 seconds. Drizzle the icing over the monkey bread. Let set before serving.

Notes
To serve, place a plate or platter on top of the Bundt pan and carefully invert it, allowing the monkey bread to release onto the plate.
