Whip together the cream cheese, sugar, egg and vanilla for 3 minutes until everything is evenly combined and smooth.
Preheat your oven to 350 degrees F.
Line a 9x13 baking pan with tin foil and spray it with non-stick baking spray.
Press 1/2 of the cookie dough mixture into the bottom of the pan to make 1 even layer.
Spread the cheesecake mixture on top of the cookie dough.
Crumble and sprinkle the remaining cookie dough on top of the cheesecake mixture and then sprinkle with the remaining chocolate chips
Place it into the oven and bake for 40-45 minutes until the cookie dough is golden brown. The inner part of the dish might look a bit jiggly, but not to fear. Once the Cheesecake Cookie Bars have baked, remove them from the oven and let them cool on the counter for 30 minutes. Then transfer them to the fridge and cool completely for at least 2 hours. Cut and serve as needed.
