Preheat the oven to 350 degrees F and grease a 9×13-inch baking dish with non-stick cooking spray, set aside.
In a large bowl with a hand mixer, beat together the cream cheese, 1 cup of sugar, and vanilla until smooth and creamy.
Melt the chocolate chips on 30-second intervals, stirring between each interval until fully melted. (This can be done in a microwave-safe bowl in the microwave or in a double boiler)
Add the melted chocolate into the cheesecake mixture and beat with a hand mixer until fully blended.
Unroll the crescent roll dough sheets and press one of the rolls of dough into the bottom of the prepared baking dish. If the dough doesn’t cover your baking dish, no worries, it will when you’re done.
Top the dough with the cream cheese mixture, spreading it evenly over the dough.
Top the filling with the other piece of dough and gently press it down.
In a bowl, mix together the sugar, cinnamon and butter until combined and dollop it over the top of the dough.
Bake for 30 to 35 minutes until the top layer of dough is a golden brown and has puffed up.
Remove from the oven and place on a wire rack to cool to room temperature. Then place in the refrigerator to cool completely.
Cut into squares and serve with chocolate syrup if desired.
