Ingredients:
- 1 ¼ cups All-Purpose Flour
- 1 tablespoon Granulated Sugar (for crust)
- ½ teaspoon Fine Sea Salt (for crust)
- 8 tablespoons Unsalted Butter, very cold, cubed (for crust)
- 3–5 tablespoons Ice Water
- 1 ½ cups Whole Milk
- ½ cup Heavy Cream
- ¾ cup Granulated Sugar (for filling)
- 4 Large Egg Yolks
- ¼ cup Cornstarch
- ¼ cup Dutch-Process Cocoa Powder
- 6 ounces Dark Chocolate (70% cocoa), finely chopped
- 2 tablespoons Unsalted Butter (for filling), cubed
- 1 teaspoon Pure Vanilla Extract
- ¼ teaspoon Salt (for filling)
- 1 ½ cups Heavy Cream, cold (for topping)
- 2 tablespoons Icing Sugar, sifted
- ½ teaspoon Pure Vanilla Extract (for topping)
Instructions:
- Prepare the Dough: Whisk together flour, sugar, and salt. Cut in the very cold butter until the mixture resembles coarse crumbs. Sprinkle ice water over the mixture, 1 tablespoon at a time, mixing until the dough just comes together. Do not overmix.
- Chill Dough: Form the dough into a flat disc, wrap tightly, and chill in the refrigerator for at least 1 hour.
- Roll and Fit: Roll the dough into a 12-inch circle. Gently transfer to a 9-inch pie plate, trimming and crimping the edges. Prick the bottom all over with a fork (docking).
- Freeze and Blind Bake: Freeze the lined pie shell for 20 minutes. Preheat the oven to 375°F (190°C). Line the frozen crust with parchment paper and fill with pie weights. Bake for 15 minutes.
- Finish Baking: Remove the parchment and weights. Return the crust to the oven and bake for another 8–10 minutes, until lightly golden brown. Cool completely.
- Melt Chocolate Prep: Place the chopped dark chocolate and 2 tablespoons of butter in a heatproof bowl; set aside.
- Mix Dry Ingredients: In a separate medium bowl, whisk the egg yolks, sugar, cornstarch, cocoa powder, and salt until smooth and light yellow.
- Heat Dairy: Combine the whole milk and heavy cream in a saucepan and heat over medium heat until steaming, but not boiling.
- Temper the Yolks: Slowly drizzle about 1 cup of the hot milk mixture into the egg yolk mixture, whisking continuously to temper the eggs.
- Cook the Custard: Pour the tempered yolk mixture back into the saucepan with the remaining dairy. Cook over medium-low heat, whisking constantly until the filling thickens significantly and coats the back of a spoon (about 5–7 minutes).
- Finish the Filling: Pour the hot custard immediately over the bowl containing the chopped chocolate and butter. Let stand for 2 minutes, then whisk until the chocolate is fully melted and the filling is uniform, glossy, and smooth. Stir in the vanilla extract.
- Assemble and Chill: Pour the warm chocolate filling into the cooled pie shell. Place the pie, uncovered, into the refrigerator and chill for a minimum of 4 hours, or preferably overnight, until the filling is fully set and firm.
- Whip Topping: Just before serving, combine the cold heavy cream, icing sugar, and vanilla extract. Whip until stiff peaks form.
- Garnish and Serve: Dollop or pipe the whipped cream over the chilled pie, slice using a sharp knife dipped in hot water, and enjoy.
