Combine sugar and cinnamon in a small bowl and set aside. Divide the dough into individual roll sized portions. Press each portion into a flat circle.Place
1 large marshmallow in the center of each roll. Pinch roll dough very firmly around the marshmallow. Roll each into a seamless, or nearly seamless, ball with your hands. Brush rolls with melted butter. Sprinkle sugar mixture over rolls. Cover rolls with plastic wrap and put in the fridge overnight.On Sunday morning, preheat oven to 350°. Take rolls out of fridge and bake for 15 minutes until rolls are golden brown. Be careful not to overbake.(These may also be baked without sitting overnight. After wrapping the marshmallow in them, let them rise for about an hour or so and then bake them as usual.)
