01 - Preheat oven to 350°F. Generously grease a bundt pan with unsalted butter or nonstick spray.
02 - Open the canned biscuit or cinnamon roll dough. For biscuits, cut each round into quarters. For cinnamon rolls, unroll and cut each into bite-sized segments.
03 - Combine granulated sugar and ground cinnamon in a mixing bowl. Toss dough pieces in the cinnamon sugar mixture to evenly coat all sides.
04 - Arrange the cinnamon-sugar coated dough pieces evenly in the prepared bundt pan.
05 - Mix melted butter, light brown sugar, and vanilla extract until smooth. Pour evenly over the dough in the pan, ensuring even distribution.
06 - Bake for 30 to 35 minutes or until the top of the bread is golden brown and the interior is set.
07 - Allow to cool in the pan for 10 minutes. Carefully invert onto a serving plate.
08 - Whisk powdered sugar, milk, and vanilla extract until smooth. Drizzle the icing over the warm monkey bread before serving.
