Ingredients for Dark Chocolate Mousse Cake
- 200g high-quality dark chocolate (60-70% cocoa), chopped
- 100g unsalted butter, cubed and softened
- 4 large eggs, separated
- 120g granulated sugar (divided: 60g + 60g)
- 60g all-purpose flour, sifted
- 2 tbsp unsweetened cocoa powder
- 1 tsp pure vanilla extract
- 200ml heavy whipping cream
- 1/4 tsp salt
- Extra dark chocolate for shavings or curls (optional, for garnish)
- Fresh berries and mint leaves (optional, for garnish)
Instructions for Making Dark Chocolate Mousse Cake
- Preheat your oven to 170°C (340°F) and line the base of a 20cm (8-inch) springform cake pan with parchment paper. Lightly grease the sides.
- Melt the chopped dark chocolate and unsalted butter together in a heatproof bowl over gently simmering water (double boiler method), stirring frequently until smooth. Remove from heat and allow to cool slightly.
- In a large bowl, use an electric mixer to beat the egg yolks and 60g of sugar until pale, creamy, and doubled in volume, about 3-4 minutes.
- Fold in the cooled chocolate-butter mixture into the beaten egg yolks. Add the vanilla extract and mix gently until just combined.
- Sift together the all-purpose flour and cocoa powder, then fold these dry ingredients into the chocolate mixture. Set aside.
- In a clean bowl, beat the egg whites and salt until soft peaks form. Gradually add the remaining 60g sugar and beat until stiff, glossy peaks are achieved.
- Gently fold one-third of the beaten egg whites into the chocolate mixture to lighten it. Then carefully fold in the remaining whites until fully incorporated, taking care not to deflate the batter.
- Pour the batter into the prepared pan, smooth the surface, and bake for 25-30 minutes (the center should still be slightly moist; do not overbake).
- Let the cake cool completely in the pan. The cake will shrink slightly, pulling from the sides—this is normal.
- For the mousse: In a heatproof bowl, gently melt the remaining 150g dark chocolate (if making a thicker mousse layer) over simmering water or in a microwave in short bursts, stirring until smooth. Let cool.
- Whip the heavy cream until soft peaks form.
- Fold a quarter of the whipped cream into the cooled melted chocolate to lighten, then gently fold in the rest until fully combined and the mixture is light and airy.
- Spread the chocolate mousse evenly over the cooled cake base in the pan. Smooth the top, cover, and refrigerate for at least 4 hours or overnight for best results.
- Once set, carefully unmold the cake from the pan. Garnish with dark chocolate shavings, fresh berries, and mint leaves if desired. Slice with a hot, clean knife for neat portions. Serve chilled.
Nutritional Information
Dark Chocolate Mousse Cake is a rich and satisfying dessert, so it’s best enjoyed in moderation.
A typical slice (1/12 of the cake) contains approximately 340 calories, with around 25g of fat (primarily from cream, butter, and chocolate), 32g of carbohydrates (of which about 18g are sugars), and 5g of protein.
The cake is also a good source of iron and magnesium due to the high-quality dark chocolate content. Dark chocolate is also renowned for containing antioxidants known as flavonoids, which can help promote heart health and reduce inflammation.
However, given the presence of sugar and saturated fat, those managing their sugar or fat intake should plan their servings accordingly.

Remember, pairing this dark chocolate mousse cake with fresh fruit or a side of yogurt can help balance its richness, making it both a delicious and mindful treat as part of a balanced diet.
Wine/Beverage Pairings With Dark Chocolate Mousse Cake
Pair your dark chocolate mousse cake with drinks that complement its rich, deep cocoa notes. Full-bodied red wines such as a Cabernet Sauvignon or a Malbec play nicely with the intense chocolate, enhancing both the wine and the dessert.
A Ruby Port, with its sweet berry undertones, also creates a luxurious pairing. For non-alcoholic options, try a bold cold brew coffee, espresso, or a rich black tea like Earl Grey, whose citrus notes beautifully cut through the cake’s richness.
If you appreciate a creamy contrast, serve with a glass of cold milk or a silky vanilla milkshake—it helps balance the bittersweet flavors for kids and adults alike.
Cooking Tips and Variations
To ensure your Dark Chocolate Mousse Cake turns out perfectly, consider a few expert tips. First, use high-quality dark chocolate with at least 60% cocoa solids for the best depth of flavor and silky mousse texture. Room temperature eggs help provide volume and stability when whipping.
Be careful not to overbake the cake base—pull it from the oven when it’s just set in the center, as residual heat will finish cooking it without drying it out.
For variation, you can add a splash of espresso to intensify the chocolate flavor, or fold in orange zest for a citrus brightness.
Swapping half the dark chocolate with milk chocolate will yield a milder, sweeter result; substituting dairy cream with coconut cream and using plant-based margarine enables a dairy-free version. For those who desire a gluten-free cake, choose an appropriate flour blend or almond flour.
If you wish for an extra layer of crunch, sprinkle the cake base with crushed hazelnuts or toasted almonds before adding the mousse. Presentation-wise, always serve it well-chilled and use a hot knife to achieve smooth, clean slices.
Serving Suggestions
Dark Chocolate Mousse Cake is a versatile dessert ideal for serving at dinner parties, birthdays, anniversaries, or even as an elegant finish to a casual meal. For a refined touch, present each slice on a chilled dessert plate to keep the mousse firm and refreshing.
Garnish with a handful of fresh berries such as raspberries, strawberries, or blackberries to add a natural tartness that contrasts with the dense chocolate. A sprig of fresh mint or a light dusting of cocoa powder enhances the aesthetic appeal.
For added texture and flavor, offer a dollop of lightly sweetened whipped cream or a scoop of vanilla gelato on the side. If you’re serving the cake at a festive gathering, edible gold leaf or chocolate curls can create a spectacular centerpiece.
For larger events, consider making mini mousse cakes in ramekins or silicone molds for individual servings, ensuring everyone gets their fair share. Always slice with a sharp, heated knife for perfect layers, and wipe between cuts to keep the presentation pristine.
Remember to serve the cake slightly chilled—it helps preserve the mousse's structure and provides the best mouthfeel.
Dark Chocolate Mousse Cake Health Benefits
While Dark Chocolate Mousse Cake tastes irresistibly decadent, it can also contribute to well-being when enjoyed thoughtfully. Dark chocolate, with its abundance of polyphenols and antioxidants, is linked to heart health, improved blood circulation, and mood elevation due to the presence of serotonin and endorphin-boosting compounds.
Consuming moderate amounts of high-cocoa-content chocolate can help protect cells from oxidative stress. Additionally, quality dark chocolate provides minerals like iron, magnesium, and zinc, all essential for the body’s functioning. Opting for quality ingredients—organic eggs, real butter, and pure vanilla—enhances both flavor and nutritional profile.
However, as the cake does contain sugar and rich dairy, people with dietary restrictions should moderate their intake and substitute where necessary.

Pairing small servings with fresh fruit or yogurt can further boost the health benefits, ensuring this dessert fits within a balanced diet.
FAQs About Dark Chocolate Mousse Cake
Can I make Dark Chocolate Mousse Cake in advance?
Absolutely! Dark Chocolate Mousse Cake actually benefits from refrigeration as it allows the flavors to meld and the mousse to set firmly. Prepare the cake a day ahead, cover tightly, and refrigerate until ready to serve.
What’s the best type of chocolate to use for this cake?
Quality matters—choose a dark chocolate with at least 60-70% cocoa solids for rich, intense flavor and a silky mousse. Avoid compound chocolates, as they lack the depth and creaminess achieved with premium couverture.
How can I adapt the recipe for gluten-free or dairy-free diets?
Easily swap the flour for your favorite gluten-free blend or almond flour. For dairy-free, use plant-based butter alternatives and coconut cream in place of dairy cream. Always check labels to ensure all ingredients align with dietary needs.
My mousse seems runny. What went wrong?
Ensure the chocolate is cooled before folding in the whipped cream and don’t overwhip the cream or overfold the mixture. Chilling the assembled cake for several hours is key for a firm, sliceable mousse.
Can I freeze leftover Dark Chocolate Mousse Cake?
Yes, you can freeze the cake after it’s set. Wrap slices individually or the whole cake tightly in plastic wrap and foil. Thaw in the refrigerator overnight before serving for best texture.
