Roll each roll into a 9-inch rope. Place butter in a shallow bowl and sugar in a separate shallow bowl. Dip the rolls in butter and then in sugar. Tie into a knot and place in a sprayed muffin cup.
Repeat with the rest of the rolls. Cover with sprayed plastic wrap and let rise until double in size. Remove wrap and bake at 350°F 10-15 minutes or until deep golden brown.
Remove from pan immediately and place on cooling rack.
