A layered tart featuring a cocoa pastry crust, dark chocolate ganache base, creamy pistachio custard center, and a glossy chocolate topping, balanced in sweetness and texture with an elegant presentation.

Ingredients

  • Cocoa Pastry Crust: 1 1/4 cups all-purpose flour, 1/4 cup unsweetened cocoa powder, 1/3 cup powdered sugar, 1/2 cup cold unsalted butter (cubed), 1 large egg or 1 egg yolk, pinch of salt
  • Base Ganache: 200g dark chocolate (60% cacao or higher), 3/4 cup heavy cream, 1 teaspoon vanilla extract, pinch of salt
  • Pistachio Cream: 1 cup shelled pistachios or pistachio paste, 1/2 cup milk, 1/2 cup heavy cream, 1/3 cup granulated sugar, 1 tablespoon cornstarch (or 1 egg yolk for richness), optional 1/2 teaspoon almond extract
  • Top Ganache: 150g dark chocolate, 1/2 cup heavy cream, 1 tablespoon unsalted butter (room temperature)
  • Topping: roasted or raw shelled pistachios, whole or chopped, for garnish

Instructions

  1. Prepare the cocoa pastry crust by combining flour, cocoa powder, powdered sugar, cold butter, egg or yolk, and salt until dough forms. Press into a tart pan and bake until fragrant, smelling like brownies. Let cool completely.
  2. Warm heavy cream for the base ganache to a gentle simmer.
  3. Pour hot cream over chopped dark chocolate (60% cacao or higher) and stir gently from center outward until glossy and smooth. Add vanilla extract and pinch of salt.
  4. Pour base ganache into cooled tart shell and chill in refrigerator for about 30 minutes to firm.
  5. Blend shelled pistachios with milk until very smooth.
  6. Transfer pistachio mixture to a saucepan, add cream, granulated sugar, and cornstarch (or egg yolk). Cook while stirring constantly until thickened, then remove from heat immediately.
  7. Spoon or spread the pistachio cream into the center of the chilled ganache base layer.
  8. Heat cream for top ganache to just simmering, pour over chopped dark chocolate, stir until smooth, then whisk in room temperature butter for shiny finish.
  9. Pour thin, glossy top ganache over tart, stopping short of covering crust edge to reveal some pistachio layer. Spread gently without overworking.
  10. Scatter roasted or raw shelled pistachios over top and chill until ganache is set and tart is firm.

Notes

For clean slicing, remove tart from refrigerator 15–20 minutes before serving. Use a thin, sharp knife warmed with hot water and wiped dry between cuts., Tart can be made a day ahead and stored in refrigerator for up to three days., For a gluten-free crust, substitute all-purpose flour with almond flour or gluten-free flour blend., To make vegan/dairy-free, use dairy-free chocolate, coconut cream for ganache, and vegan butter or coconut oil for shine. Use cornstarch or agar agar for pistachio cream thickening., Add a teaspoon of orange zest to pistachio cream or a sprinkle of flaky sea salt on top ganache for flavor variations., Serve plain or with fresh fruit to complement nutty flavors.
