Unroll the cans of crescent roll dough, and use a rolling pin to shape each piece into 9×13 inch rectangles. Press one piece into the bottom of a 9×13 inch baking dish. Evenly spread the cream cheese mixture into the baking dish, then cover with the remaining piece of crescent dough. Stir together 3/4 cup of sugar, cinnamon, and butter. Dot the mixture over the top of the cheesecake.
