Cut bread dough into 16 pieces; shape into balls. Place on a floured surface; cover and let rise in a warm place for 10 minutes. In a bowl, stir Parmesan cheese and garlic powder into butter. Using a spoon, roll balls in butter mixture; arrange loosely in a 9-in. round baking pan.
Cover and let rise in a warm place until doubled. Bake at 375° for 10-15 minutes or until golden brown. Warm leftover butter mixture; when rolls are baked, pull them apart and dip them again. Serve warm.
