Preheat your oven to 350°F (175°C) and grease a bundt pan or a deep dish oven-safe skillet with non-stick cooking spray.
In a mixing bowl, combine the granulated sugar and ground cinnamon until well mixed.
Open the cans of cinnamon rolls and cut each roll into quarters.
Dip each quarter piece of dough into the melted butter, then roll it in the cinnamon-sugar mixture to coat well.
Layer half of the coated dough pieces evenly in the prepared bundt pan. If you’re using nuts and raisins, sprinkle half of them over this layer.
Add the remaining dough pieces on top of the first layer and sprinkle the remaining nuts and raisins, if you are using them.
Pour any leftover melted butter over the top, ensuring an even drizzle.
Sprinkle a little extra cinnamon-sugar over the top if desired.
Bake in the preheated oven for about 30-35 minutes or until the bread is golden brown and cooked through.
Remove from the oven and let the monkey bread cool in the pan for about 10 minutes.
Carefully flip the pan upside down onto a serving plate to release the monkey bread.
Drizzle the icing that came with the cinnamon rolls over the warm monkey bread for added sweetness.
Notes
Serve warm, and consider garnishing with extra chopped pecans or a dusting of powdered sugar for a festive look. Enjoy pulling apart the gooey, sweet pieces!
