1 cup sugar (divided)
2 teaspoons cinnamon
1 cup butter
1/2 cup brown sugar
Take 3 packages of buttermilk biscuit tubes (10 per roll) and cut each roll into 4 pieces. Drop roll pieces into 1 cup sugar and 2 teaspoons cinnamon. Drop sugar-coated pieces into a well buttered Bundt pan (don't squish roll pieces when placing them in the Bundt pan).
Put 1/2 cup of the left-over sugar/cinnamon mix and 1/2 cup packed brown sugar and 1 cup of butter (2 sticks) into a small saucepan.
Bring this mixture just to a boil; remove from heat immediately. Carefully drizzle over the roll pieces.
Bake at 350°F for 30 minutes.
Cool slightly in an upright position, then tip pan over onto a plate to remove monkey pull-apart bread.
