Ingredients:
- 1 ½ cups (190g) all-purpose flour, plus more for dusting
- ¼ cup (25g) unsweetened cocoa powder
- ½ cup (100g) granulated sugar
- ¼ teaspoon salt
- ½ cup (113g) unsalted butter, cold and cut into small cubes
- 4-6 tablespoons (60-90ml) ice water
- 8 ounces (227g) bittersweet chocolate, finely chopped
- ½ cup (120ml) heavy cream
- 2 tablespoons (28g) unsalted butter
- 6 ounces (170g) bittersweet chocolate, finely chopped
- 3 large eggs, separated
- ¼ cup (50g) granulated sugar
- 1 cup (240ml) heavy cream, cold
Instructions:
- Make the Chocolate Crust: Combine dry ingredients in a food processor or bowl. Cut in the butter until crumbly. Gradually add ice water until the dough comes together. Flatten into a disc, wrap in plastic wrap, and chill.
- Roll and Bake the Crust: Roll out the chilled dough and fit it into the pie plate. Crimp the edges. Prick the bottom with a fork and blind bake (cover with parchment paper and baking weights or dried beans) until lightly golden. Remove weights and bake until golden brown. Let cool completely.
- Prepare the Chocolate Ganache: Heat heavy cream in a saucepan until simmering. Pour over chopped chocolate and let sit for a minute. Stir until smooth. Stir in butter.
- Assemble the Ganache Layer: Pour the ganache into the cooled pie crust and spread evenly. Refrigerate to set.
- Make the Chocolate Mousse: Melt chocolate in a double boiler or heatproof bowl over simmering water.
- Whip the Egg Yolks: In a separate bowl, whisk egg yolks and sugar until pale and thick.
- Combine Chocolate and Yolks: Gradually whisk melted chocolate into the yolk mixture.
- Whip the Egg Whites: In a clean bowl, beat egg whites until stiff peaks form.
- Whip the Cream: In another clean bowl, whip heavy cream until stiff peaks form.
- Fold Everything Together: Gently fold the whipped egg whites into the chocolate mixture, then gently fold in the whipped cream.
- Assemble the Mousse Layer: Spoon the mousse over the ganache layer in the pie crust. Spread evenly.
- Chill: Refrigerate for at least 4 hours, or preferably overnight, to allow the mousse to set completely, creating the perfect chocolate mousse pie.
