Crush the Oreos using a food processor or in a large plastic bag and a rolling pin. Mix the crushed Oreos and the melted butter.
Press into the bottom and sides of a 9-inch pie pan.
Peanut Butter Filling
Add the peanut butter and cream cheese in a medium bowl. Beat together until well combined. Beat in the whipped topping until well combined. Spread this mixture over the Oreo curst. Refrigerate while you work on the chocolate topping.
Chocolate Topping
To a microwave-safe bowl add the chocolate chips and whipping cream. Place in the microwave and heat for 30 seconds at a time, stirring after every 30 seconds, until it is completely melted. Pour over the top of the pie. Refrigerate for at least two hours. Garnish with crushed Reese's and enjoy!
