In a medium bowl, combine the crushed Oreo cookies, melted butter, granulated sugar, and salt. Mix until well combined and press the mixture into the bottom of the graham cracker crust to form an even layer.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Gradually add the powdered sugar and vanilla extract, mixing until fully incorporated.
In another bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until combined.
Pour the cream cheese mixture over the crust and spread it evenly. Refrigerate for at least 4 hours, or until set.
Before serving, garnish with additional crushed Oreo cookies on top. Slice and enjoy!
