Set cinnamon roll icing aside. Seperate dough into individual rolls; roll out each into a 4-inch circle. Arrange on a greased 12 inch pizza pan, overlapping edges. Bake at 400F for 8 minutes.
Pull rolls from oven and spoon the apple pie filling over rolls to within 1/2 inch of the edge. Combine the brown sugar and butter; sprinkle over pie filling. Bake 6-8 minutes longer or until the crust is golden brown. Cool. Drizzle with the reserved icing from the cinnamon dogh tube. 10-12 servings
