Lightly grease a 10 inch bundt cake pan. Place frozen rolls into the pan and sprinkle with brown sugar, the pudding mix, and cinnamon. Pour melted butter over the top. If you do't have a bundt pan, you can use a muffin tin, but they turn out better in a bundt pan. Cover with a clean, damp cloth and leave overnight at room temperature to rise. In the morning, preheat the oven to 350 degrees. Bake rolls for 25 minutes, until golden brown. Turn rolls out onto a serving plate and dig in!
