Preheat oven to 350 degrees Fahrenheit.

Prepare a 9x13 inch baking dish with cooking spray.

In a mixing bowl, beat the softened cream cheese, 3/4 cup of sugar, and vanilla extract until smooth.

Set the cream cheese mixture aside.

Unroll the two packages of reduced-fat refrigerated crescent rolls.

Using a rolling pin, shape each package of dough into a 9x13 inch sheet.

Press one sheet of dough into the bottom of the prepared baking dish.

Spread the cream cheese mixture evenly over the dough in the dish.

Cover the cream cheese mixture with the second sheet of dough.

Melt 1/2 cup of butter.

Brush the melted butter over the top layer of dough.

In a small bowl, mix together 1/2 cup of sugar and 1 teaspoon of cinnamon.

Sprinkle the sugar and cinnamon mixture evenly over the buttered dough.

Bake in the preheated oven for approximately 30 minutes, or until the dough is puffed and golden brown.

Let cool slightly before slicing and serving.
