In a small bowl, mix the brown sugar, sugar, pudding mix and cinnamon. Place 12 rolls in a greased 10-in. fluted tube pan; layer with half of the sugar mixture, 1/2 cup pecans and 1/4 cup butter. Repeat layers.
Cover with a kitchen towel; let thaw and rise at room temperature until doubled, about 6-8 hours.
Bake at 350° for 25-30 minutes or until golden brown. (Cover loosely with foil if top browns too quickly.) Cool for 5 minutes before inverting onto a serving plate. Serve warm.
