In a medium bowl, combine the Oreo cookie crumbs and melted butter. Mix until well combined.
Press the mixture firmly into the bottom of a 9-inch springform pan to form the crust. Place in the refrigerator to chill for 10 minutes.
In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until fully incorporated and creamy.
In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until no white streaks remain.
Pour the cheesecake filling over the chilled crust and spread it evenly. Sprinkle the crushed Oreo cookies on top.
Cover the cheesecake with plastic wrap and refrigerate for at least 4 hours, or overnight for best results.
Before serving, garnish with whole Oreos around the edge of the cheesecake. Slice and enjoy!
