Preheat your oven to 350 degrees F. Line an bread loaf pan with parchment paper or grease it lightly.

Slice the refrigerated cookie dough log into 1/4-inch thick rounds.

Arrange just over half of the slices in the bottom of the prepared baking pan. Press them together to form an even cookie dough layer, covering the entire bottom of the pan.

In a medium bowl, beat the softened cream cheese until smooth.

Add the granulated sugar and continue to beat until well combined and creamy.

Beat in the egg and vanilla extract until the mixture is smooth and well combined.

Pour the creamy cheesecake mixture over the cookie dough base. Spread it out evenly with a spatula.

Crumble the remaining cookie dough over the cheesecake layer, covering it as evenly as possible.

Place the pan in the preheated oven and bake for 32-37 minutes, or until the cheesecake layer is set and the cookie dough is golden brown.

Remove the pan from the oven and let it cool completely on a wire rack. Then, refrigerate for at least 2 hours to allow the bars to set.

Once chilled, cut the bars into squares using a sharp knife and serve. Enjoy your delicious Chocolate Chip Cookie Dough Cheesecake Bars!
