Lightly grease a 10 inch Bundt cake pan. Place frozen rolls into pan and sprinkle with brown sugar, pudding mix, ground cinnamon and raisins. Pour melted butter over rolls. Cover with a clean, damp cloth and leave overnight at room temperature.
In the morning, preheat oven to 350 degrees F (175 degrees C). Bake rolls for 25 minutes, until golden brown. Turn rolls out onto a serving plate and serve warm.
