Ingredients
For the Chocolate Tart Shells:
- 1 1/2 cups all-purpose flour
- 1/4 cup unsweetened cocoa powder
- 1/3 cup powdered sugar
- 1/4 teaspoon salt
- 1/2 cup (1 stick) cold unsalted butter, cubed
- 1 large egg yolk
- 2-3 tablespoons ice water
For the Dark Chocolate Mousse:
- 8 ounces high-quality dark chocolate (70% cocoa), chopped
- 2 tablespoons unsalted butter
- 3 large eggs, separated
- 1/4 cup granulated sugar, divided
- 1 cup heavy cream
- 1 teaspoon vanilla extract
- Pinch of salt
For the Raspberry Coulis:
- 2 cups fresh raspberries (plus extra for garnish)
- 3 tablespoons granulated sugar
- 1 tablespoon lemon juice
- 1 teaspoon cornstarch mixed with 1 tablespoon water (optional, for thickening)
For Garnish:
- Fresh raspberries
- Mint leaves
- Dark chocolate shavings
- Powdered sugar for dusting
Instructions
For the Chocolate Tart Shells:
- In a food processor, combine flour, cocoa powder, powdered sugar, and salt. Pulse to mix.
- Add cold butter cubes and pulse until mixture resembles coarse crumbs.
- Add egg yolk and 2 tablespoons of ice water. Pulse just until dough begins to come together. If needed, add the remaining tablespoon of water.
- Turn dough onto a lightly floured surface and form into a disk. Wrap in plastic and refrigerate for at least 1 hour.
- Preheat oven to 350°F (175°C).
- Roll out the chilled dough to about 1/8-inch thickness. Cut circles slightly larger than your tart pans.
- Carefully press dough into 4-inch tart pans with removable bottoms. Trim excess dough.
- Prick bottoms with a fork, then line with parchment paper and fill with pie weights or dried beans.
- Bake for 15 minutes, then remove weights and parchment. Bake for another 5-7 minutes until fully cooked.
- Allow to cool completely before filling.
For the Dark Chocolate Mousse:
- In a heatproof bowl set over simmering water (not touching), melt chocolate and butter together, stirring occasionally until smooth. Remove from heat and let cool slightly.
- In a clean bowl, beat egg whites with a pinch of salt until foamy. Gradually add 2 tablespoons of sugar and continue beating until soft peaks form. Set aside.
- In another bowl, whip heavy cream with vanilla and remaining 2 tablespoons of sugar until soft peaks form.
- Whisk egg yolks into the cooled chocolate mixture one at a time, ensuring each is fully incorporated before adding the next.
- Gently fold one-third of the whipped egg whites into the chocolate mixture to lighten it. Then fold in the remaining egg whites carefully to maintain airiness.
- Finally, fold in the whipped cream until just combined and no streaks remain.
- Cover and refrigerate for at least 2 hours or until ready to assemble tarts.
For the Raspberry Coulis:
- In a saucepan, combine raspberries, sugar, and lemon juice.
- Cook over medium heat, stirring occasionally, until raspberries break down and release their juices, about 5-7 minutes.
- For a smoother consistency, strain the mixture through a fine-mesh sieve to remove seeds, pressing with a spoon to extract all the liquid.
- Return strained liquid to the saucepan. If you prefer a thicker coulis, add the cornstarch slurry and simmer for 1-2 minutes until thickened.
- Allow to cool completely before using.
Assembly:
- Carefully remove the cooled tart shells from their pans.
- Spoon or pipe the chocolate mousse into each tart shell, filling them almost to the top.
- Smooth the surface with an offset spatula if needed.
- Spoon a layer of raspberry coulis over the mousse, gently spreading it to the edges.
- Refrigerate for at least 30 minutes to set.
- Just before serving, garnish with fresh raspberries, mint leaves, and chocolate shavings.
- Dust lightly with powdered sugar if desired.
These Dark Chocolate Raspberry Mousse Tarts are truly a show-stopping dessert that balances richness with brightness in every bite. The chocolate crust provides the perfect crunchy foundation for the ethereal mousse, while the raspberry coulis cuts through the richness with its tangy sweetness. What makes this dessert particularly special is how the flavors evolve as you eat it – the initial burst of raspberry gives way to the deep, complex flavor of the dark chocolate, creating a truly memorable tasting experience.
One of the greatest advantages of this recipe is its flexibility. You can prepare the components in advance – the tart shells can be baked a day ahead and stored in an airtight container, the mousse can be made up to 24 hours in advance, and the raspberry coulis keeps well in the refrigerator for up to three days. This makes them perfect for entertaining, as you can simply assemble everything shortly before your guests arrive. The individual servings also eliminate the need for tableside cutting and serving, allowing your guests to dive right into dessert heaven.
For those concerned about raw eggs in the mousse, you can use pasteurized eggs, or alternatively, you could gently heat the egg yolks with a bit of the sugar over a double boiler until they reach 160°F (71°C) before incorporating them into the chocolate mixture. If you’re catering to different dietary needs, you can also experiment with dairy-free alternatives. Coconut cream works wonderfully as a substitute for heavy cream in the mousse, lending a subtle tropical note that pairs beautifully with both the chocolate and raspberry.
The visual impact of these tarts cannot be overstated. The glossy dark chocolate mousse contrasted with the vibrant red raspberry coulis creates a stunning presentation that’s sure to impress. For special occasions, consider adding edible gold leaf or silver dragées for an extra touch of elegance. If you’re making these for a romantic dinner, you could shape the tarts into hearts rather than circles for a more thematic presentation. The versatility of this recipe allows for endless creative interpretations while maintaining the core flavor profile that makes it so irresistible.
In terms of serving suggestions, these tarts pair beautifully with a variety of accompaniments. A small scoop of vanilla bean ice cream creates a lovely temperature contrast with the chilled mousse. For the adults at the table, a glass of ruby port or raspberry liqueur makes for a delightful pairing that enhances the fruit flavors in the dessert. Coffee enthusiasts will appreciate how the bitter notes in an espresso complement the dark chocolate, creating a balanced end to any meal.
Whether you’re an experienced baker or trying your hand at a more elaborate dessert for the first time, these Dark Chocolate Raspberry Mousse Tarts are sure to become a favorite in your recipe collection. The combination of rich chocolate and bright raspberry is timeless for good reason – it simply works, delighting palates and creating moments of pure culinary joy.
