01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan or line with parchment paper.
02 - Combine 1/2 cup granulated sugar and 2 teaspoons ground cinnamon in a small bowl. Set aside.
03 - Unroll one can of crescent roll dough and press evenly into the bottom of the prepared pan, sealing any seams.
04 - Sprinkle half of the cinnamon-sugar mixture over the crescent dough in the pan.
05 - In a large bowl, beat the softened cream cheese until smooth. Add 1/2 cup granulated sugar, egg, and vanilla extract, and mix until creamy and uniform.
06 - Evenly spread the cream cheese mixture over the prepared dough layer in the baking pan.
07 - Unroll the second can of crescent roll dough and gently place it over the cream cheese filling, covering completely.
08 - Brush the melted butter evenly over the top layer. Sprinkle with the remaining cinnamon-sugar mixture.
09 - Bake for 30 to 35 minutes, or until the surface is golden brown and the center is set.
10 - Allow to cool completely in the pan, then refrigerate for at least 2 hours before cutting into bars.
