Preheat your oven to 350 degrees Fahrenheit and prepare a 9x13 baking sheet by lining it with parchment paper.
In a small bowl, mix together ½ cup of sugar and 3 tablespoons of ground cinnamon for the topping; set this cinnamon sugar mixture aside.
In a medium bowl, use a hand mixer to beat together the cream cheese, sugar, egg, and vanilla extract until the mixture is creamy and smooth.
Lightly sprinkle some of the prepared cinnamon sugar mixture onto the bottom of your lined baking pan.
Carefully unroll one can of crescent rolls, placing it to cover the bottom of the baking pan. Make sure to press the seams together to form a single sheet.
Evenly pour the cream cheese mixture over the crescent roll layer in the baking pan.
Unroll the second can of crescent rolls, placing it on top of the cream cheese layer, to cover it completely.
Generously sprinkle the remaining cinnamon sugar mixture over the top of crescent rolls.
Bake the assembled cheesecake in the preheated oven for 30-40 minutes, or until the top is a light golden brown in color.
Notes
Ensure Even Layers: For the best texture and presentation, take your time to ensure that the crescent roll layers are evenly spread out and the seams are well pressed together. This creates a uniform base and top for your cheesecake bars.
Room Temperature Ingredients: Make sure your cream cheese and egg are at room temperature before blending. This helps achieve a smoother, creamier cheesecake filling without lumps.
Check for Doneness: Ovens can vary, so start checking your cheesecake at the 30-minute mark to prevent overcooking. The ideal color is a light golden brown, and a slight jiggle in the center means it's set perfectly.
Cool Before Slicing: For clean, sharp slices, allow the cheesecake to cool completely in the pan, then chill in the refrigerator for at least an hour. This makes it easier to cut through the layers without crushing them.
Cinnamon Sugar Adjustment: Feel free to adjust the amount of cinnamon sugar to your liking. Some prefer a heavier coating for extra sweetness and flavor, while others might like it more subtle.
Spreading the Cream Cheese Layer: Use an offset spatula to spread the cream cheese mixture smoothly over the crescent roll layer. This tool can help you cover the area more evenly without tearing the dough.
Using Parchment Paper: For the best results, don't skip lining your pan with parchment paper. It not only prevents sticking but also allows you to easily lift the entire cheesecake out for neater slicing.
