Spray a 9×13 baking dish with cooking spray. sprinkle the pecans into the bottom of the dish and place the frozen cinnamon rolls in the pan.
In a saucepan over low heat combine sugars, butter and ice cream until melted and sugars are dissolved. pour mixture evenly over the rolls. Cover lightly with plastic wrap sprayed with cooking spray. Let rise in a warm place over night.
In the morning, remove plastic wrap and bake at 350 degrees for 20-25 minutes. After they cool just a little while, invert the rolls into another pan the same size or onto a platter, then the sticky part and nuts will be on the top.
