Brush dough with oil or water. Sprinkle on cinnamon-sugar mixture adding raisins, if desired. Roll up, beginning at the wide side. Pinch edge of dough into roll to seal well. Stretch dough to make even.
Place rolls slightly apart on greased baking pans.
Cover and let rise until doubled. Bake at 375 degrees F for 25-30 minutes. While warm, frost with icing if desired.
