Take the frozen dough balls out and set them aside. Use the softened butter to grease the inside of a bundt pan.
In a medium-sized bowl, mix the melted butter, brown sugar, and cinnamon. Sprinkle pecans over the bottom of the pan and drizzle about ⅓ of the butter mixture. Add the frozen rolls, filling the pan about ⅔ full. Aim for 24-26 rolls, giving them space to rise.
Sprinkle dry pudding mix and the remaining butter mixture over and between the rolls. Loosely cover with Saran wrap sprayed with nonstick cooking spray. Let it rise for 3 hours or overnight (if preparing ahead, let it rise in a cold oven).
After rising, gently push down the rolls in the pan. Preheat the oven to 325°F. Bake for 30-35 minutes until the dough turns golden brown. Allow it to sit for 5 minutes, then invert onto a dish and cut slices to serve. Enjoy the delightful flavors of this easy-to-make Monkey Bread!
