To make monkey bread using frozen dough, cut the thawed dough into bite-sized pieces, then dip each one in butter and cinnamon-sugar. Place the dough in a bundt pan and pour the remaining butter and sugar over it. Allow the dough to rise before baking it until golden brown.
Allow the frozen bread dough to sit at room temperature for about an hour. Once thawed, cut the dough into even, bite-sized pieces. If using frozen bread rolls, you may only need to cut the dough in half for each roll, or not at all, depending on your preference. Melt about 1/2 to 1 cup of butter and combine 1 cup of sugar with 2 teaspoons of cinnamon. Add more or less cinnamon to taste. You can also add a 1/2 cup of chopped nuts, such as pecans, as an option.
Lightly grease a bundt pan and set aside. Dip each piece of dough first into the melted butter, then into the sugar-cinnamon mix, ensuring all the pieces are well-coated. Next, place each piece into the bundt pan in even layers. Combine the remaining butter and cinnamon-sugar mixture and pour it evenly over the dough. Preheat the oven to 350 degrees Fahrenheit and allow the dough to rise until it reaches the rim of the pan. Bake for about 30 to 40 minutes, until the bread is fully browned. Allow it to cool slightly before inverting it onto a serving platter.
