First, Heat oven to 350°F.
Next, Spray a 9x13 glass baking dish with cooking spray.
Then unroll 1 can of crescent roll dough and press into the bottom of the prepared 9x13 baking dish. Stretch it out to cover the bottom of the pan and pinch together the perforations. Don't worry if it is not perfect, it will be covered up with the cheesecake layer.
Then stir together the remaining 1/2 cup sugar with the cinnamon, and sprinkle evenly over butter.
Finally, bake about 35 minutes or until center is set.
Cool for about 20 minutes.
Refrigerate to allow the Sopapilla Cheesecake Bars to set and to make it easier to cut.
