Dark Chocolate Pistachio Tart (Printable)

Crisp cocoa crust filled with silky dark chocolate ganache and topped with crunchy pistachios for an elegant French dessert.

# What You'll Need:

→ Chocolate Tart Crust

01 - 1½ cups all-purpose flour
02 - ¼ cup unsweetened cocoa powder
03 - ½ cup powdered sugar
04 - ¼ teaspoon fine sea salt
05 - ½ cup unsalted butter, cold and cubed
06 - 1 large egg yolk
07 - 2 to 3 tablespoons cold water

→ Dark Chocolate Ganache Filling

08 - 9 ounces high-quality dark chocolate (60–70% cocoa), finely chopped
09 - ¾ cup plus 2 tablespoons heavy cream
10 - 2 tablespoons unsalted butter, softened
11 - 1 teaspoon pure vanilla extract

→ Pistachio Topping

12 - ⅓ cup shelled pistachios, roughly chopped
13 - Flaky sea salt, to taste

# Directions:

01 - In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, powdered sugar, and fine sea salt until evenly distributed.
02 - Add the cold cubed butter to the flour mixture. Using a pastry cutter or your fingertips, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
03 - Add the egg yolk and 2 tablespoons of cold water to the crumb mixture. Gently fold and press the dough together until it just holds its shape. Add the remaining tablespoon of water only if the dough remains too dry and crumbly.
04 - Shape the dough into a flat disc, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes to relax the gluten and firm the butter.
05 - On a lightly floured surface, roll the chilled dough out to an 11-inch round, about ⅛ inch thick. Carefully transfer it into a 9-inch tart pan with a removable bottom. Press the dough firmly into the corners and fluted edges, then trim away any overhang. Prick the base evenly with a fork and chill for 15 minutes.
06 - Preheat the oven to 350°F. Line the chilled crust with parchment paper and fill with baking weights or dried beans. Bake for 15 minutes. Remove the weights and parchment, then continue baking for 8 to 10 minutes until the crust looks dry and set. Allow it to cool completely in the pan.
07 - Place the finely chopped dark chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer around the edges. Immediately pour the hot cream over the chocolate and let it sit undisturbed for 2 minutes.
08 - Starting from the center, stir the chocolate and cream together in small circles until the mixture becomes completely smooth and glossy. Stir in the softened butter and vanilla extract until fully incorporated and the ganache has a silky consistency.
09 - Pour the finished ganache into the cooled tart shell, using an offset spatula to smooth the surface into an even layer.
10 - Scatter the roughly chopped pistachios evenly across the surface of the ganache. Finish with a light pinch of flaky sea salt if desired.
11 - Refrigerate the assembled tart for at least 2 hours, or until the ganache is firmly set and no longer jiggles when gently shaken.
12 - Remove the tart from the pan and place it on a serving plate. Dip a sharp knife in hot water, wipe it dry, and slice cleanly through the tart for neat, professional edges. Reheat and wipe the knife between each cut.

# Expert Tips:

01 -
  • The cocoa laced crust alone is worth making, shattering beautifully against the smooth ganache like two textures having a conversation.
  • It looks wildly impressive but the real work is mostly waiting for things to chill, which means you can socialize while it sets.
02 -
  • If the crust dough cracks while rolling, patch it directly in the pan with your fingers because cocoa dough is forgiving and the patches bake invisible.
  • Letting the ganache sit undisturbed while chilling is essential because jostling it too early creates wobbly textures that never fully recover.
03 -
  • Run your knife under hot water and wipe it dry between every single slice for edges so clean they look like they were cut by a machine.
  • The chocolate you choose is the entire personality of this tart, so taste it plain first and make sure it is something you genuinely enjoy eating on its own.
