Ingredients

• 1.5 cups all-purpose flour
• 1 tablespoon white sugar
• 0.5 teaspoons salt
• 6 tablespoons cold unsalted butter , cubed
• 3 tablespoons cold shortening , cut into chunks
• 4 tablespoons ice water , or more as needed

Instructions

1. 1 Prepare crust: Pulse flour, sugar, and salt in a food processor 3 to 4 times or until combined. Add butter and shortening and pulse 10 to 12 times or until mixture resembles coarse meal. Drizzle 4 tablespoons ice water over mixture; pulse 5 to 6 times or until dough clumps together, adding up to 1 tablespoon water, 1 teaspoon at a time, if necessary. Gently shape dough into a flat disk. Wrap in plastic wrap, and chill for 30 minutes.
2. 2 Preheat the oven to 400 degrees F (200 degrees C).
3. 3 Roll dough into a 12-inch circle (about 1/8 inch thick) on a floured surface. Fit into a 9-inch pie plate; turn edges under and crimp. Prick the bottom and sides with a fork. Line pastry with parchment paper, and fill with pie weights or dried beans.
4. 4 Bake in the preheated oven for 12 minutes. Remove pie weights and parchment paper and continue to bake until lightly browned and crisp, 10 to 12 minutes more. Transfer to a wire rack and cool while preparing filling.
5. 5 Prepare filling: Whisk together sugar, flour, cocoa powder, and salt in a large saucepan. Whisk together heavy cream, milk, and egg yolks in a medium bowl until completely blended. Gradually whisk egg mixture into sugar mixture.
6. 6 Cook over medium heat, whisking constantly, just until mixture begins to boil, 6 to 8 minutes. Cook for 1 more minute, whisking constantly. Remove from heat and whisk in semisweet chocolate, bittersweet chocolate, butter, and vanilla until chocolate and butter have melted and mixture is completely smooth.
7. 7 Spread filling in the cooled crust. Place plastic wrap directly on the warm filling and chill in the refrigerator until set, 8 to 24 hours.
8. 8 Prepare topping: Beat heavy cream and vanilla at medium-high speed with an electric mixer until foamy. Gradually add 3 tablespoons sugar, beating until soft peaks form.
9. 9 Just before serving, top pie with whipped cream.
