Preheat oven to 375°F. Spray a fluted tube pan with cooking spray.
Open crescent rolls and tear along perforations. Roll each triangle up. Cut into one-inch pieces. Place half of dough in the pan. Spread ⅛ cup each of chopped pecans and butterscotch chips on top.
Put remaining dough in pan and top with the rest of the butterscotch chips and pecans.
Mix together melted butter and brown sugar. Pour evenly into pan.
Bake for 35 to 40 minutes or until dough is cooked all over and golden brown. Let cool 10 minutes before flipping upside down a serving plate. Serve warm.
