Preheat your oven to 350°F (175°C). Wrap a 9-inch springform pan with two layers of heavy-duty aluminum foil tightly.
Process 24-26 Oreos into fine crumbs using a food processor. Mix with 5 tbsp melted butter until it looks like wet sand.
Press the mixture firmly into the bottom and 1 inch up the sides of the pan. Bake for 12 minutes, then let it cool completely.
Lower the oven temperature to 325°F (165°C).
Beat the room-temperature cream cheese and sour cream together on medium speed for 2-3 minutes until perfectly smooth with no lumps.
Gradually add the granulated sugar on low speed. Then, add the eggs and egg yolks one at a time, mixing just until combined (do not overbeat).
Stir in the heavy cream and vanilla extract. Gently fold in the 12-15 chopped Oreos using a spatula.
Pour the filling over the cooled crust. Place the springform pan inside a larger roasting pan and fill it halfway with hot water (water bath).
Bake at 325°F (165°C) for 1 hour and 20 minutes until the edges are set but the center still jiggles slightly.
Turn off the oven and leave the cheesecake inside with the door closed for 30 minutes.
Remove from the water bath, discard the foil, and cool to room temp (2-3 hours). Refrigerate for at least 6 hours or overnight before decorating and serving.
