Divide Cinnamon Roll Dough into 6 equal portions. Roll each portion into a 13- x 9-inch rectangle on a lightly floured surface. Spread each rectangle evenly with 2/3 cup filling, using the back of a spoon. Roll up jellyroll fashion. Cut each roll into 16 slices. (An electric knife works best.) Place rolls, cut sides up, in 2 buttered 15- x 10-inch jellyroll pans. Cover and let rise in a warm place (85°), free from drafts, 15 to 20 minutes.
Bake rolls at 350° for 20 to 25 minutes. Remove from oven, brush with melted butter, and drizzle with Cinnamon Roll Icing.
