Dark Chocolate Mousse Cups
A Classic Dessert Served the Lang’s Chocolates Way 🍫
There’s something timeless about dark chocolate mousse. It’s rich, silky, and indulgent without being heavy — the kind of dessert that feels elegant yet comforting at the same time. For this recipe, we’re taking that classic French-inspired mousse and serving it in Lang’s Chocolates dark chocolate cordial cups, turning dessert into a fully edible experience from the first bite to the last.
These mousse cups are perfect for dinner parties, holidays, or anytime you want a dessert that looks impressive but doesn’t require complicated techniques. The chocolate cups do the heavy lifting — adding structure, flavor, and a beautiful presentation all on their own.
Why Chocolate Cups Make the Difference
Using Lang’s Chocolates dark chocolate cordial cups isn’t just about convenience — it’s about balance. The firm snap of real dark chocolate pairs perfectly with the light, airy mousse inside. Unlike disposable cups or ramekins, these are meant to be enjoyed completely, leaving no waste and no dishes.
Each cup delivers:
-
A clean chocolate flavor (not waxy or overly sweet)
-
Portion control without feeling skimpy
-
A professional, bakery-style presentation at home
Ingredients & Why We Use Them
Dark Chocolate (70% cacao)
The backbone of the mousse. Dark chocolate provides depth, richness, and just enough bitterness to keep the dessert from becoming overly sweet.
Unsalted Butter
Butter adds silkiness and body to the melted chocolate, helping the mousse set smoothly while enhancing mouthfeel.
Heavy Cream
Whipped cream brings lightness. Folding it into the chocolate mixture transforms dense melted chocolate into an airy mousse.
Eggs (Separated)
-
Egg yolks add richness and structure
-
Egg whites whipped to soft peaks provide lift and volume, giving the mousse its signature fluffiness
Sugar
Used sparingly to stabilize the egg whites and balance the bitterness of dark chocolate without overpowering it.
Boiling Water
A small amount helps loosen the melted chocolate, ensuring it blends smoothly with the eggs and cream.
Lang’s Chocolates Dark Chocolate Cordial Cups
The star of the show — rich, snappy, and perfectly sized for individual desserts.
Fresh Raspberries (Optional)
A bright, slightly tart contrast that cuts through the richness of the chocolate.

125 g (about 4.4 oz) 70% dark chocolate, chopped
-
2 tablespoons unsalted butter

1 tablespoon boiling water
-
3 large eggs, separated
-
2 teaspoons sugar
-
1 cup cold heavy cream
-
Fresh raspberries or chocolate shavings, for garnish (optional)
Instructions
-
Melt the Chocolate
In a heatproof bowl set over a double boiler (or gently in the microwave), melt the dark chocolate and butter together until smooth. Stir in the boiling water and allow the mixture to cool slightly. -
Whip the Cream
In a cold bowl, whip the heavy cream to soft peaks. Refrigerate until ready to use. -
Whip the Egg Whites
In a separate bowl, beat the egg whites with the sugar until soft peaks form. Set aside. -
Add the Yolks
Once the chocolate mixture has cooled to warm (not hot), stir in the egg yolks one at a time. -
Fold Gently
Fold half of the whipped cream into the chocolate mixture until just combined. Then gently fold in half of the whipped egg whites. Repeat with the remaining cream and egg whites. -
Fill the Cups
Spoon or pipe the mousse into the chocolate cordial cups. -
Chill
Refrigerate for at least 8 hours, or overnight, to fully set. -
Serve
Remove from the refrigerator about 30 minutes before serving. Garnish with raspberries or chocolate shavings if desired.

Frequently Asked Questions
Can I make these ahead of time?
Yes! These are ideal for make-ahead desserts. Prepare them up to 48 hours in advance and keep refrigerated.
Do the chocolate cups get soggy?
No. Lang’s Chocolates cordial cups are made with real, tempered chocolate, which holds up beautifully against chilled mousse.
Can I pipe the mousse instead of spooning it?
Absolutely. Piping creates a cleaner, more professional look — especially for events or gift trays.
Do I need to use raspberries?
Not at all. They’re optional. Chocolate curls, cocoa powder, or even a drizzle of melted chocolate work beautifully.
Can I freeze these?
Freezing isn’t recommended. Mousse texture is best when chilled, not frozen.
