1. Prepare the Cookie Crust:

• Preheat the oven to 350°F (175°C).
• Arrange the cookie dough pieces evenly in an ungreased 13×9-inch baking pan.
• Press the dough to form an even crust.
• Bake for 9 to 13 minutes until lightly golden brown.
• Remove from the oven and let cool for 10 minutes.

2. Make the Cheesecake Filling:

• In a large mixing bowl, beat the softened cream cheese, sugar, vanilla extract, and eggs until smooth and creamy.
• Pour the cheesecake mixture over the cooled cookie crust, spreading it evenly.

3. Add the Nutella Swirls:

• Slightly warm the Nutella in the microwave for 10 to 20 seconds until softened.
• Drop small spoonfuls of Nutella over the cheesecake layer.
• Use a knife to gently swirl the Nutella, creating a marbled effect.

4. Bake and Chill:

• Bake the cheesecake bars for 25 to 30 minutes, or until the filling is set.
• Allow to cool at room temperature for 30 minutes, then refrigerate for at least 2 hours until fully chilled.

5. Serve:

• Cut into 8 rows by 4 rows to create 32 bars.
• Store covered in the refrigerator until ready to serve.
