You will need an Oreo cookie crust for this recipe. You can buy one premade (as I did this time) or make your own.
Here is how you make the crust.Crush 20 Oreo cookies. You do not need to remove the cream filling. You can crush them in a food processor or you can place them in a Ziploc and whack them with something heavy like a rolling pin. Melt 5 tbsp butter. I do this in a heatproof dish in the microwave. It only takes 30-40 seconds.
Put the cookie crumbs into a bowl and toss with the melted butter.
When the mixture is moistened, place it all in an 8" or 9" pie plate. Begin by pressing the mixture in with your fingers, working along the bottom and up the sides. You can use a measuring cup to press everything in evenly and securely.
Set the crust aside.
Place the whisk attachment on your mixer.
Pour the one cup of heavy whipping cream into the mixer's bowl and whip at medium high speed for 2-3 minutes until firm, whipped cream peaks form.
The whipped cream is done when you can remove the beater and flip it over without the cream losing shape. DO NOT OVER MIX. If you mix cream too long, you will have butter.
Set this aside. If you don't have two mixing bowls, place the cream in another bowl while you make the rest of the filling.
Melt the chocolate in a microwave safe dish. I do this in 30 second increments, stirring between heating. It is usually still too hard to mix after the first 30 seconds.
Put the paddle attachment on the mixer and put the softened cream cheese, sour cream, confectioner's sugar, vanilla, and melted chocolate into the bowl.
Mix until thoroughly combined, scraping the sides and the paddle.
Add the whipped cream to the mixture. You can gently use the mixer to combine. When it is just combined finishing mixing with a spatula.
Pour the mixture into the prepared crust. Smooth out the surface with a spatula.
Decorate the top of your pie. You can use chopped chocolate, chocolate chips, white chocolate, malted milk balls...there are tons of choices!
Cover the pie lightly with foil or plastic wrap and let it chill thoroughly - about 4 to 6 hours.
