- 1 ¼ cups all-purpose flour
- ¼ cup Dutch process cocoa powder
- ¼ cup granulated sugar
- ¼ teaspoon salt
- ½ cup cool (not cold) butter, cut into pieces
- Large egg yolk
- 1 tablespoon cool water
- Truffle Layer:
- ½ cup whipping cream
- 113 grams chopped bittersweet chocolate
- 2 tablespoons granulated sugar
- Large egg, at room temperature
- 1 teaspoon vanilla extract
- Fluffy Layer:
- Large eggs
- ⅓ cup granulated sugar
- 2 tablespoons water
- Pinch salt
- 340 grams milk chocolate, chopped
- ½ cup nsalted butter, at room temperature
- 1 cup whipping cream
- 1 teaspoon vanilla extract
- Chocolate shavings, for décor
- For the crust, sift the flour, cocoa, sugar and salt into a large mixing bowl or in the bowl of a stand mixer fitted with the paddle attachment. Add the butter and cut in (using a pastry cutter, if mixing by hand) until a rough crumbly texture, and no large bits of butter are visible. Whisk the egg yolk and water together and add this to the bowl, and blend until the dough just comes together. Shape this into a disc, wrap in plastic wrap and chill for at least 2 hours.
- Lightly knead the dough a minute on a lightly floured surface, to soften it just slightly. Roll the dough out into a circle just under ¼-inch (6 mm) thick. Line a 9-inch (23 cm) fluted removable-bottom tart pan with the pastry and press in, trimming away any excess. Chill this for at least 30 minutes.
- Preheat the oven to 325 °F (160 °C). Dock the bottom of the pastry with a fork (this prevents the crust from developing air pockets) and bake for about 20 minutes, until the pastry loses its shine at the centre of the shell. Cool the pan on a rack and keep the oven at 325 °F (160 °C).
- For the truffle layer, bring the cream to a boil in a small saucepan (watch it carefully – it will boil up quickly) and pour this over the chopped chocolate. Let this sit for 30 seconds then slowly stir it until smooth. Whisk in the sugar. Break the egg into a small dish and stir it a little before adding to the chocolate along with the vanilla and whisking in well. Pour the truffle filling into the cooled shell and bake for 10 minutes (there will be no visible difference – it will still seem fluid). Cool the tart on a rack and then chill for at least an hour.
- For the fluffy layer, whisk the eggs, sugar, water and salt in a metal bowl placed over a pot of gently simmering water and whisk vigorously until the mixture holds a ribbon when the whisk is lifted, about 8 minutes. Pour this directly over the chopped milk chocolate and whisk until smooth, returning to the heat if needed, to make sure there are no unmelted chocolate bits. Set aside to cool to room temperature (this won’t take too long).
- Using electric beaters, or placing the chocolate base into the bowl of a stand mixer fitted with the whip attachment, add the butter and whip until it is fully incorporated. In a separate bowl whip the cream and vanilla to a soft peak and fold into the chocolate until evenly combined. Spread this over the tart (it will be soft but not fluid) and chill for at least 3 hours before serving. Use a vegetable peeler to make chocolate shavings and sprinkle them overtop the tart.
