03In a small bowl, combine the next two ingredients(brown sugar and cinnamon). Stir well until the ingredients are thoroughly mixed. Then, spread the softened butter over the surface of the dough and sprinkle cinnamon sugar mixture evenly over the dough surface. Use all of the cinnamon sugar and completely coat the dough.
04Preheat the oven to 400 degrees. Roll up the sheet of dough jelly-roll fashion along the 16" wide side of the rectangle (lengthwise). Then, cut the dough roll into 12 slices.
05Spray a 9” by 13” baking pan with non-stick cooking spray. Arrange these 12 rolls into the baking pan. Cover and let rise until nearly doubled. Place into the preheated oven. Bake for approximately 15 minutes, or until lightly browned on top.
06While the rolls bake, combine the last 5 ingredients in a medium sized mixing bowl. Stir until everything is well blended. The mixture should form a thick icing.
07When the rolls are fully cooked, remove the baking pan from the oven. Frost the rolls immediately with the icing, while they are still in the pan. Then, allow the rolls to cool until they are able to be handled.
08For best results, the rolls should be served within 30 minutes of baking.
