Step 1: Prepare the Oreo Crust

1. Preheat your oven to 325°F (163°C).
2. Crush the Oreos into fine crumbs using a food processor or by placing them in a sealed bag and crushing them with a rolling pin.
3. Mix the crushed Oreos with melted butter until fully combined.
4. Press the mixture firmly into the bottom of a 9-inch springform pan, making sure it’s even. Use the back of a spoon or a flat-bottomed glass to press it down tightly.
5. Bake the crust for 10 minutes, then remove from the oven and let it cool while you prepare the filling.

Step 2: Make the Cheesecake Filling

1. In a large mixing bowl, beat the softened cream cheese and granulated sugar until smooth and creamy (about 2-3 minutes).
2. Add the vanilla extract and mix until incorporated.
3. Beat in the eggs, one at a time, mixing just until combined after each addition. Avoid overmixing to prevent cracks.
4. Mix in the sour cream and heavy cream, ensuring a silky-smooth consistency.
5. Fold in the crushed Oreos, distributing them evenly throughout the batter.

Step 3: Assemble and Bake the Cheesecake

1. Pour the cheesecake batter over the cooled Oreo crust, spreading it out evenly.
2. Tap the pan gently on the counter to release any air bubbles.
3. Wrap the bottom of the springform pan with aluminum foil, then place it in a large roasting pan. Fill the roasting pan with about 1 inch of hot water to create a water bath (this helps prevent cracks).
4. Bake at 325°F (163°C) for 55-60 minutes, or until the edges are set but the center is slightly jiggly.
5. Turn off the oven and let the cheesecake sit inside with the door slightly open for 1 hour. This helps prevent cracks.
6. Remove from the oven and cool completely before refrigerating for at least 4 hours (preferably overnight).

Step 4: Prepare the Whipped Topping (Optional)

1. In a cold mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
2. Spread or pipe the whipped cream over the chilled cheesecake.
3. Garnish with extra crushed Oreos and whole cookies for decoration.

Step 5: Serve and Enjoy!

Carefully remove the cheesecake from the springform pan, slice, and serve chilled. Enjoy every creamy, Oreo-packed bite!
