Roll the dough out on a lightly floured surface. Roll dough flat until it is approximately 21 inches long and 16 inches wide. It should be about 1/4 inch thick. 5. Preheat oven to 400 degrees 6. For the filling, combine the brown sugar and cinnamon in a bowl. Spread the softened margarine evenly over the surface of the dough, and then sprinkle the cinnamon and sugar evenly over the surface. 7. Working carefully from the top, roll the dough in the bottom edge. 8. Cut the rolled dough into 1 3/4-inch slices and place 6 at a time evenly spaced in a lightly greased baking pan. Bake for 10 minutes or until light brown on top 9. While the rolls bake, combine the icing ingredients. Beat well with an electric mixer until fluffy. 10. When the rolls come out of the oven, coat each generously with icing. FROM: http://www.recipesource.com/baked-goods/pastries/02/rec0243.html
