01 - Preheat oven to 350°F (175°C). Thoroughly grease a 10-inch bundt pan with butter or nonstick spray.
02 - Open the refrigerated cinnamon roll dough cans. Reserve the icing for later use. Cut each cinnamon roll into quarters.
03 - In a large zip-top bag, combine the granulated sugar and ground cinnamon. Add the quartered dough pieces, seal the bag, and shake until thoroughly coated.
04 - Evenly layer the cinnamon sugar-coated dough pieces into the prepared bundt pan.
05 - In a small bowl, whisk together the melted unsalted butter and light brown sugar until well combined.
06 - Pour the butter and brown sugar mixture evenly over the dough pieces distributed in the bundt pan.
07 - Bake for 30–35 minutes, or until the top surface is golden brown and the dough is fully cooked.
08 - Allow the monkey bread to cool in the pan for 10 minutes. Carefully invert the pan onto a serving plate to unmold.
09 - While the monkey bread cools, prepare the glaze by beating together the reserved cinnamon roll icing, softened cream cheese, and milk until smooth.
10 - Drizzle the prepared cream cheese glaze over the warm monkey bread just before serving.
