Sprinkle nuts in the bottom of a greased Bundt pan. Lay frozen roll dough on top of nuts. Sprinkle pudding mix, brown sugar, and cinnamon over dough. Pour melted margarine over mixture. Lay a damp paper towel over the pan and place it in a cold oven for 8 hours to overnight.

Remove the pan from the oven in the morning. Discard the paper towel.

Preheat the oven to 350 degrees F (175 degrees C).

Bake in the preheated oven for 25 minutes. Remove from the oven and let sit for a few minutes, then invert onto a plate.
