For the tart shell:
- 1 large egg yolk
- 1 tbsp. heavy cream
- 1/2 tsp. vanilla extract
- 1 cup all-purpose flour, plus more for dusting the work surface
- ¼ cup Dutch-process cocoa powder
- 2/3 cup confectioners’ sugar
- 1/4 tsp. salt
- 8 tbsp. cold unsalted butter, cut into 1/2-inch cubes
For the filling:
- 4 cups fresh cherries, pitted and halved
- 3-4 tbsp. sugar
- 1 cup heavy cream
- 3 tbsp. confectioners’ sugar
- 1 tsp. vanilla extract
- Chocolate syrup (optional)

To make the tart shell, whisk together the egg yolk, cream and vanilla in a small bowl; set aside. Place the flour, cocoa powder, sugar, and salt in a food processor. Process briefly to combine. Scatter the butter pieces over the flour mixture; process to cut the butter into the flour until the mixture resembles coarse meal, about fifteen 1-second pulses. (Note: This can just as easily be done with a stand mixer or by hand with a pastry cutter.) With the machine running, add the egg mixture and process until the dough just comes together, about 12 seconds. Turn the dough onto a sheet of plastic wrap and press into a 6-inch disc. Wrap in plastic wrap and refrigerate at least 1 hour or up to 48 hours.

Remove the dough from the refrigerator. (If refrigerated for more than an hour, let stand at room temperature until malleable.) Unwrap and roll the dough out on a lightly floured surface to a 13-inch round. Transfer the dough to a 9-inch tart pan. Mold the dough to the sides of the tart pan and remove the excess off the top. Set the dough-lined tart pan on a large plate and freeze for 30 minutes.

Meanwhile, adjust an oven rack to middle position. Preheat the oven to 375° F. Set the dough-lined tart pan on a baking sheet, press a 12-inch square of foil into the frozen shell and over the edge, and fill with pie weights. Bake for 30 minutes, rotating halfway through the baking time. Remove from the oven and carefully remove the foil and weights. Continue to bake until deep golden brown, 5-8 minutes longer. Transfer to a wire rack to cool.

Increase the oven temperature to 450˚ F. Combine the cherries and sugar in a baking dish. Toss to combine. Bake for about 10 minutes, until the cherries have softened slightly and start to release their juices. Let the cherries cool completely before assembling the tart.

In the bowl of a stand mixer fitted with the whisk attachment, combine the heavy cream and confectioners’ sugar. Whip on medium-high speed until medium-stiff peaks form. Blend in the vanilla. Spoon about two-thirds of the roasted cherries into the cooled tart shell to form an even layer. Top with the whipped cream and smooth into an even layer over the cherries. Spoon the remaining cherries over the top of the whipped cream. If desired, drizzle a bit of chocolate syrup over the top. Refrigerate until ready to serve.
