Preheat the oven to 350 degrees F and line a 9x9 square baking pan with parchment paper; set aside.
Add approximately ¾ of the cookie dough to the bottom of the pan and use your hands to spread it out to cover the whole pan make sure no breaks in the dough remain.
In a large mixing bowl, beat together the cream cheese, eggs, sugar, and vanilla on medium speed until smooth and creamy, about 1 minute.
Spread the cheesecake mixture over the top of the sugar cookie dough making sure to evenly cover it.
Take the remaining sugar cookie dough and pinch it between your fingers to create thinner pieces of dough and place them on top of the cheesecake layer. They do not need to meet or seal as they will spread during baking.
Sprinkle the sprinkles over the top of the cookie dough layer.
Bake for 45 to 55 minutes, the cookies should be light gold in color and the center should jiggly slightly.
Place the cheesecake pan on a wire rack to cool for 1 hour.
Transfer to the refrigerator to chill for at least 3 hours before slicing.
