In medium mixing bowl, beat cream cheese until fluffy {to avoid lumps make sure cream cheese is really soft or place in microwave for 20 seconds}. Add in vanilla extract and granulated sugar. Beat until combined and creamy.
In separate bowl, beat the heavy whipping cream until stiff peaks form. This will take several minutes.
Using a rubber spatula, add the whipped cream into the cream cheese mixture and gently mix together. Fold in the crushed Oreo cookies and combine.
Dump into the pie crust and smooth the top. Refrigerate for at least 6 hours before serving. I prefer to refrigerate overnight.
Before serving, garnish with additional whipped cream and crushed Oreos if wanted.
