Creating a Cookie Dough Cheesecake is a straightforward process if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C).
2. Make the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until well combined. Press the mixture firmly into the bottom of a 9-inch springform pan.
3. Prepare Cookie Dough: In another bowl, cream together softened butter, brown sugar, and granulated sugar. Add vanilla and milk, mixing until smooth. Gradually add flour and mix until combined. Fold in mini chocolate chips. Set aside.
4. Make Cheesecake Filling: In a large bowl, beat the softened cream cheese until smooth. Gradually add granulated sugar and vanilla, mixing well. Add eggs one at a time, mixing until just blended. Finally, add sour cream and flour, mixing until smooth.
5. Layer the Cheesecake: Pour half of the cheesecake batter over the crust in the springform pan. Drop spoonfuls of the cookie dough over the cheesecake layer. Pour the remaining cheesecake batter on top, smoothing it out gently.
6. Bake: Bake in the preheated oven for 55-60 minutes, or until the center is set but slightly jiggly.
7. Cool: Turn off the oven and crack the door open, letting the cheesecake cool in the oven for 1 hour.
8. Chill: Remove from the oven and refrigerate for at least 4 hours, or preferably overnight, to let the flavors meld and the cheesecake set properly.
9. Remove from Pan: Once chilled, carefully remove the sides of the springform pan.
10. Serve: Slice and serve your Cookie Dough Cheesecake, garnishing with extra chocolate chips or whipped cream if desired.
