Step 1: Prepare the Oreo Crust. Crush the Oreo cookies in a food processor or zip-top bag until fine crumbs. Combine with melted butter and press into a pie dish.
Step 2: Make the Creamy Filling. Beat softened cream cheese until smooth, gradually add powdered sugar, and fold in whipped topping.
Step 3: Assemble the Pie. Scoop the filling into the crust, smooth it out, and drizzle with chocolate syrup if desired.
Step 4: Chill the Pie. Cover with plastic wrap and refrigerate for at least 4 hours or overnight before serving.
Notes
For a richer flavor, use double stuff Oreos. Ensure cream cheese is at room temperature to avoid lumps.
