Spray a bundt pan or an angel food cake pan with nonstick cooking spray.
Place the rolls in the pan, sprinkle the whole package of butterscotch pudding mix over the rolls, sprinkle the brown sugar over the pudding mix, pour the butter over the brown sugar, and top with the pecans.
Cover and place in the refrigerator overnight, or let rise for 4-5 hours before baking.
Preheat oven to 350*. Bake the rolls for 20-25 minutes. Let cool.
