Last week, faced with the delightful challenge of cooking for a very large gathering, I needed a dessert that was not only delicious but also easy to prepare and capable of feeding a crowd without requiring endless hours in the kitchen. My thoughts immediately turned to this Dark Chocolate Mousse. It’s a dessert that consistently garners rave reviews and never disappoints, making it my go-to for special occasions and impromptu feasts alike. Its minimal prep time and universal appeal, from the youngest guests to the most seasoned palates, truly make it a standout choice.
There’s a reason why Dark Chocolate Mousse remains a culinary icon. It’s elegant, rich, and delivers an unparalleled sensory experience with every spoonful. Can you truly ever go wrong with such a perfect balance of intense chocolate flavor and delicate lightness? I think not!
This particular recipe draws inspiration from the legendary Alain Ducasse’s classic ‘Chocolate Mousse‘. I found his original recipe in French and, while it’s a masterpiece in its own right (you can find it here if you’re interested!), I’ve made only very slight modifications to adapt it for a home kitchen, primarily focusing on ingredient availability and streamlining the process. Therefore, all credit for the genius behind this divine dessert goes to him!

Elevating Your Mousse: Choosing the Right Dark Chocolate
The secret to an exceptional chocolate mousse truly lies in the quality and type of chocolate you choose. For me, when it comes to any chocolate dessert, the darker the cooking chocolate, the more sublime the result. While taste is subjective, I personally gravitate away from overly sweet desserts, finding immense pleasure in the robust, complex, and slightly bitter notes of high-quality dark chocolate. This depth of flavor truly distinguishes a good mousse from a truly unforgettable one.
The Cacao Percentage Matters: Understanding Bitterness and Flavor
Dark chocolate is defined by its high percentage of cacao solids and lower sugar content. A 70% dark chocolate, for example, offers a rich, intense flavor with a pleasant bitterness that balances the sweetness from other ingredients in the mousse. Going higher, to 80% or even 90%, will result in an even more profound and sophisticated chocolate experience, catering to those who truly appreciate the unadulterated essence of cacao. Conversely, if you or your guests prefer a milder chocolate flavor, a 50-60% dark chocolate can still yield a delicious mousse, though it will naturally be sweeter.
Quality Over Quantity: Why Good Chocolate Makes a Difference
Beyond the cacao percentage, the overall quality of the chocolate is paramount. High-quality cooking chocolate melts more smoothly, incorporates better with other ingredients, and contributes a superior aroma and flavor profile to the final product. Brands that specialize in couverture chocolate are often the best choice for baking and desserts, as they are designed for optimal melting and tempering properties.
My Go-To: Callebaut 70% Dark Chocolate and Australian Sourcing Challenges
While shopping for the aforementioned party last week, I had a small moment of joy when I stumbled upon some **Callebaut 70% Dark Chocolate**. As someone who grew up in Belgium, where high-quality cooking chocolate is readily available on every corner, finding chocolate that meets my standards here in Australia has often been a struggle. Callebaut is renowned as one of the best Belgian cooking chocolates in the world, celebrated for its consistent quality and exceptional flavor. It’s typically quite expensive in Australia, so discovering an affordable supply was a genuine thrill. I ended up buying three bags, and let me tell you, I have absolutely no regrets. In fact, most of it is already gone – a testament to its irresistible quality!

Now that I’ve found a reliable source for this exceptional Callebaut chocolate, there’s truly no turning back to other brands for my baking needs. However, while I personally advocate for using the darkest chocolate you can find – because that’s how I savor my chocolate desserts – always remember to choose a chocolate you genuinely enjoy. The best recipe is one you’ll make and love!

Dark Chocolate Mousse
Print Recipe
Ingredients
- 180 gr Dark Cooking Chocolate (70% cacao recommended)
- 10 cl Heavy Cream
- 10 cl Full Fat Milk
- 20 gr Unsalted Butter
- 3 Eggs, separated, at room temperature for best results
- 1 pinch Salt
- 50 gr Granulated Sugar
Instructions
- In a small pot, gently heat the heavy cream and full-fat milk until they are warm to the touch, but crucially, do not let them boil. Overheating can scorch the dairy and alter the flavor.
- Place the chopped dark cooking chocolate (or chocolate chips) into a sturdy, heat-proof bowl. Pour the warm cream and milk mixture over the chocolate. Let it sit for about a minute to allow the heat to penetrate, then stir gently with a spatula or whisk until the chocolate is completely melted and smooth.
- While the chocolate mixture is still warm, add the unsalted butter. Continue to mix until the butter is fully integrated into the chocolate, creating a glossy, homogenous ganache. Set this aside and allow it to cool down to at least room temperature. This step is vital to prevent the eggs from cooking in the next stage.
- Carefully separate the egg yolks from the whites. Place the egg whites in a large, impeccably clean mixing bowl with the pinch of salt. Using an electric hand mixer, begin beating the egg whites on medium speed. As they start to become foamy, gradually add the granulated sugar, continuing to beat. Increase the speed to high and beat until stiff peaks are formed.
Tip: The firmness of your meringue (beaten egg whites) will directly impact the final texture of your chocolate mousse. Stiffer peaks will result in a firmer mousse, while softer peaks will yield a more delicate, liquid-like consistency. Ensure your bowl and beaters are grease-free for best results!
- Once the chocolate batter has cooled sufficiently, add the egg yolks one by one, stirring gently after each addition until fully integrated.
Important: If the chocolate mixture is too warm, it will scramble or “cook” the egg yolks, leading to an undesirable consistency in your mousse. Patience is key here!
- Gently fold the beaten egg whites (meringue) into the cooled chocolate batter. Do this in two or three additions to make it easier, using a large spatula. Use a “cut and fold” motion, bringing the mixture from the bottom up and over, being careful not to deflate the airy egg whites. The goal is to incorporate them without losing too much volume, which is what gives the mousse its characteristic lightness.
Tip: Avoid overworking the mousse at this stage. Gentle handling preserves the delicate structure of the meringue, ensuring your mousse is light and fluffy.
- Spoon the finished dark chocolate mousse into individual serving glasses or a large serving bowl. Cover it tightly with plastic wrap and refrigerate for a minimum of 2 hours, or preferably overnight, to allow it to set and for the flavors to fully develop.
Serve chilled, perhaps garnished with a dusting of cocoa powder, chocolate shavings, or fresh berries for an extra touch of elegance. Enjoy!
