This is my sister Heidi's recipe...this has replaced my grandmother's recipe as the "family chocolate pie" (sorry Grama). It's super easy and so awesomely chocolaty. It's perfect EVERY time...and it's so good, you'll be tempted to eat a whole one by yourself. Make sure you make 2, it goes FAST.
Chop chocolate with sharp knife into small pieces and set aside. NOTE** The original recipe calls for 6 squares of chocolate, but one day I only had 4 on hand and it turned out just fine!...and the nice thing about using 4 squares is that they come 8 to a box...so you can get 2 whole pies out of one box.
In microwave-safe glass bowl: combine cream, milk, egg yolks, sugar, powdered sugar, cornstarch and salt. Whisk until well-blended.
Microwave on high for 3 minutes (I have a 1000-watt microwave). Whisk.
Continue to microwave in 1 minute increments, whisking after each minute, until mixture is thick like pudding (can take up to 6 or so extra minutes depending on microwave).
Add vanilla and stir after it’s cooked. **NOTE** If you stop here you have YUMMY vanilla custard that you can serve on its own or use as a base for other custard recipes!
Add chopped chocolate to hot custard mixture and stir until all melted and blended. Add coffee (or Kahlua, if desired) now.
For HOMEMADE crust: Mix crushed oreos and butter, press FIRMLY in pie plate.
Pour in cookie crust. Chill. Serve with whipped cream or dessert topping on top.
