In a small bowl, combine brown sugar and cream until sugar is dissolved. Pour cream mixture into a greased 8-inch square baking dish. Sprinkle on walnuts.
Spray nonstick cooking spray on a clean surface. Unroll breadstick dough, being sure not to separate. Combine sugar and cinnamon and sprinkle over dough. Re-roll the dough into a tube shape. Cut along breadstick scored lines, making six rolls. Place cut side down in prepared pan.
Bake for 25-30 minutes or until golden brown. Let cool slightly and invert the pan onto a serving plate.
