Preheat the oven to 350°F. Spray a bundt pan with non-stick spray and set aside.
In a large zip bag, combine the granulated sugar and cinnamon. Add the biscuit pieces, seal the bag, and shake to coat evenly. For best results, divide the biscuits and sugar mixture between two bags.
Transfer the coated biscuits to the prepared bundt pan, spreading them out evenly. Avoid pouring the excess sugar and cinnamon into the pan.
In a medium saucepan, melt the butter over medium-high heat. Add the brown sugar and stir until fully dissolved and combined.
Remove the pan from the heat and stir in the vanilla extract.
Pour the butter-sugar mixture over the biscuits in the bundt pan, spreading it out evenly.
Bake for 35-45 minutes, or until the biscuits at the top form a hard crust.
Let the monkey bread cool for 10-15 minutes, then flip it out onto a plate or platter.
Notes
For best results, make sure each biscuit piece is well-coated in the cinnamon-sugar mixture. If needed, divide the biscuits between two bags to ensure an even coating.
Let the butter soften before melting it. This ensures the sugar and butter mix together smoothly, creating a silky glaze that coats the biscuits perfectly.
Allow the monkey bread to cool for 10-15 minutes before flipping it onto a plate. This gives the caramelized sugar time to set, so the bread holds its shape when removed from the pan.
You can add chopped nuts, chocolate chips, or raisins to the biscuit mixture for extra flavor and texture. Just make sure to mix them evenly with the dough.
The biscuits on top should form a golden-brown crust. To ensure the bread is fully cooked, check with a toothpick in the center — if it comes out clean, the bread is done.
