Make the chocolate Oreo cookie crust: Place the Oreos in a food processor and pulse to fine crumbs. Add the melted butter and pulse until the mixture resembles sand. Press the crust into the bottom and up the sides of a 9-inch springform pan. Refrigerate while preparing the filling.
Make the caramel cream filling: Beat the cream cheese in a large bowl with a handheld mixer until smooth. Add ¼ cup of the caramel sauce, the powdered sugar, and the vanilla and beat until creamy.
Beat the heavy cream in a separate bowl until stiff peaks form. (There's no need to wash the beaters from beating the cream cheese mixture.) Fold the whipped cream into the cream cheese mixture.
Pour the remaining caramel sauce into the crust and spread to the edges in an even layer. Pour the cheesecake filling on top and spread evenly. Refrigerate at least 8 hours or overnight.
To serve, remove the pie from the springform pan. Garnish with whipped cream, Oreo halves, chopped Oreos, chopped pecans, chocolate drizzle, and a drizzle of caramel sauce.
