Preheat oven to 350 degrees. Gather your ingredients so that you have everything close at hand on the counter or table. Spray a 9" square baking pan with baking spray.
Open the package of crescent rolls, and lay out one half of it to fit the pan, pinching the edges together to seal. You will need to press the dough to the edges with your fingers until the bottom of the pan is covered.
In a large mixing bowl, mix together the softened cream cheese, granulated sugar, large egg, and vanilla extract. Beat until it is soft and creamy.
Spread creamed mixture over the bottom layer of crescent dough.
Next, spread out the second half of the dough onto the counter or a sheet of waxed paper and pinch the edges together to seal. Press it out with your fingertips (or use a rolling pin, if desired) until it's the size of your pan. Then lay it over the creamed cheese mixture.
Place butter in a glass bowl and heat in a microwave for 20-30 seconds, until melted.
Pour the butter over the top layer of dough, spreading it out to the edges to cover completely.
In a small bowl, mix together the granulated sugar and ground cinnamon. Generously sprinkle the mixture over the top of the butter.
Bake in a preheated oven for 25-30 minutes until lightly browned. Allow to cool before slicing. This recipe will make 9 bars. Refrigerate any leftovers.
