Spray a bundt or angel food cake pan with vegetable spray.

Place chopped pecans in the bottom of the pan.

Arrange frozen dinner rolls evenly over the pecans.

In a separate bowl, mix butterscotch pudding mix and brown sugar.

Sprinkle the pudding mixture evenly over the rolls.

Pour melted margarine over the rolls and pudding mixture.

Cover the pan with a clean dish cloth.

Let the rolls rise overnight in a cold oven.

In the morning, remove the towel.

Bake in a preheated oven at 350 degrees F (175 degrees C) for 25 to 30 minutes.

Immediately invert the rolls onto a large platter.
