Preheat oven to 350 degrees. Spray Bundt pan with non-stick spray and set aside.
Separate and cut each biscuit into quarters. Add to a gallon sized Ziploc bag.
In a small bowl, mix granulated sugar and cinnamon then add to the Ziploc bag. Shake well, evenly coating the dough pieces. Using your hands, arrange dough pieces in the Bundt pan.
In a small bowl, melt butter in the microwave in 20 second increments until fully melted.
Add brown sugar and vanilla to the melted butter and mix well.
Using a spoon, pour the butter mixture into the Bundt pan, thoroughly coating the biscuits.
Bake for 30-35 minutes, until the top is golden brown.
Remove and allow to cool for 10 minutes before flipping the pan to remove.
Notes
Make sure you use the homestyle biscuits, not the flaky biscuits.
Mix the dough with the cinnamon and sugar in two batches to allow them to get a nice coating.
Store in an airtight container at room temperature for up to three days.
