Grease bundt pan. Sprinkle some of the nuts in the bottom of the pan. Place frozen rolls evenly in pan. Mix brown sugar and pudding mix, and sprinkle evenly over the rolls. Add raisins and nuts if using. Mix white sugar and cinnamon and sprinkle evenly over all. Pour melted butter over the ingredients in pan. Cover loosely (since it will rise) with plastic wrap and towel on a cookie sheet as ingredients may spill over sides. Leave overnight at room temperature. Rita - what I do is warm the oven to about 300 degrees and then turn off the heat. I put the rolls in the oven to rise overnight since the house is usually too cool. In the morning bake the rolls at 350 degrees for 30 minutes. Put a cookie sheet under the rolls as nuts and sauce can spill over. Once top of rolls are browned, put a piece of foil on top to keep them from getting too browned. When rolls are done, remove from oven and let sit for 5-10 minutes (not much longer as sauce will harden and make it difficult to get the rolls out of the pan). Turn rolls over onto a plate. Enjoy!
