Lightly flour your counter top and roll the dough out until it is approximately 16x20 inches, and 1/4 inch thick.
Spread softened butter all over the dough.
Sprinkle brown sugar cinnamon mixture over the top.
Carefully roll the dough from the long top edge to the bottom edge.
Carefully cut the dough into 12 to 16 even cinnamon roll slices.
Place them into the prepared baking pan.
Cover the rolls and allow them to rise for about 25-30 more minutes.
Preheat the oven to 400 degrees.
Bake rolls for 30-35 minutes, until they are golden brown and cooked throughout. After about 20 minutes cover the rolls loosely with foil so the tops don't get too brown or hard.
Remove rolls from oven and allow them to cool for about 5 minutes.
Carefully invert the pan onto a large serving platter. The warm topping will melt down the middles and sides.
