Optional: Chocolate curls or holiday sprinkles for topping
Instructions
Prepare the crust: Mix the chocolate wafer crumbs and melted butter in a bowl until combined. Press the mixture firmly into the bottom and up the sides of a 9-inch pie plate. Chill the crust for at least 30 minutes.
Make the chocolate filling: Place the chocolate chips in a medium, heatproof bowl.
In a small saucepan, heat the sweetened condensed milk over medium heat until it just begins to simmer around the edges. Do not boil.
Pour the hot milk over the chocolate chips. Let it sit undisturbed for 5 minutes.
Whisk the mixture until smooth. Stir in 1 teaspoon vanilla extract and salt.
Pour the chocolate filling into the chilled crust. Cover the pie loosely with plastic wrap and refrigerate for at least 4 hours, or until completely set. This is a good time to make it ahead.
Prepare the whipped cream topping: In a large bowl, beat the cold heavy whipping cream, powdered sugar, and 1/2 teaspoon vanilla extract with an electric mixer until stiff peaks form.
Spread or pipe the whipped cream over the set chocolate filling.
Decorate the top with chocolate curls or holiday sprinkles before serving. Keep refrigerated until ready to serve.
Notes
For a quicker crust, you can bake the crumb crust at 350 degrees F for 10 minutes, then cool before filling.
If you want a deeper chocolate flavor, use dark chocolate chips instead of semi-sweet.
You can make this entire pie up to two days in advance; add the whipped cream topping the day you plan to serve it.
