01 - Preheat oven to 350°F (180°C). Generously grease a bundt pan with butter or nonstick spray.
02 - Open canned dough. If using biscuits, cut each into quarters; if using cinnamon rolls, unroll and slice each into bite-sized pieces.
03 - Combine granulated sugar and cinnamon in a mixing bowl. Toss dough pieces in the mixture until thoroughly coated.
04 - Layer the coated dough pieces evenly in the prepared bundt pan.
05 - In a separate bowl, mix melted butter, brown sugar, and vanilla extract until cohesive. Drizzle mixture evenly over layered dough pieces.
06 - Bake for 30–35 minutes, or until the surface is golden brown and cooked throughout.
07 - Allow bread to cool in the pan for 10 minutes. Invert carefully onto a serving plate.
08 - Whisk together powdered sugar, milk, and vanilla extract until smooth. Drizzle icing over warm monkey bread before serving.
