Roll out each biscuit until it is about 1/4 inch thick and brush with melted butter. Generously sprinkle each biscuit with cinnamon sugar.  Roll up each biscuit like a burrito and cut into three pieces.  Squoosh the three pieces (with the spiral cut side facing up) into a compartment in a cupcake pan.  (To make mini cinnamon rolls, place 1 piece in one compartment of a mini cupcake pan.)  Bake according to package directions.
