Ingredients You’ll Need
Gathering the right ingredients is key to achieving that luxurious texture and deep chocolate flavor. Each component plays an essential role—from the intense dark chocolate for richness to the whipped cream for lightness, all working together to create dessert perfection.
- 3 eggs: Use fresh, cold eggs to separate the whites and yolks easily and to ensure the best texture.
- 125g / 4.5 oz dark cooking chocolate (70% cocoa): This bittersweet chocolate provides the complex, robust flavor central to the mousse.
- 10g / 0.3 oz unsalted butter: Adds smoothness and glossy shine to the melted chocolate mixture.
- 1/2 cup full-fat cream: Adds richness and helps create those soft, velvety peaks that define a great mousse.
- 3 tbsp caster sugar: Sweetens the egg whites without graininess for a fluffy, stable foam.
- More whipped cream: For garnish and an extra creamy touch on serving.
- Chocolate shavings: These add a beautiful finishing touch and a little crunch (optional but highly recommended).
How to Make Decadent Chocolate Mousse Recipe
Step 1: Prep Your Ingredients and Workspace
First, make sure your eggs are cold straight from the fridge as this helps with easier separation. Work steadily but confidently to ensure the egg whites and cream don’t warm up, which can prevent them from whipping properly. Having all your ingredients prepped and within reach makes the process smooth and enjoyable.
Step 2: Separate the Eggs
Carefully separate the egg whites into a large mixing bowl and place the yolks into a smaller bowl. Keep the whites aside for now and focus on the yolks first. Cold eggs make the separation cleaner and clearer, which is essential for the mousse’s texture.
Step 3: Whisk the Yolks
Using a whisk or an electric mixer, beat the egg yolks until they are uniform in texture and slightly pale, which will help them blend perfectly with the melted chocolate later on.
Step 4: Melt the Chocolate and Butter
Break the dark chocolate into small pieces and place them in a microwave-safe bowl with the butter. Heat in 30-second bursts, stirring thoroughly between each to prevent burning. Once melted into a smooth, glossy mixture, set it aside to cool just a bit—it should be warm but not hot for the next step.
Step 5: Whip the Cream
Whip the full-fat cream to stiff peaks, being careful not to overbeat, which turns it grainy. The whipped cream adds that essential lightness and body, creating the airy feel the mousse is known for.
Step 6: Whip the Egg Whites with Sugar
Gradually add the caster sugar to the egg whites and whisk until firm peaks form. This is the secret to a fluffy mousse, giving it volume and that melt-in-the-mouth texture.
Step 7: Combine All Components
Gently fold the cooled chocolate mixture into the beaten egg yolks until just combined. Next, carefully fold in the whipped cream, followed by the whipped egg whites, one third at a time. The folding needs to be gentle to keep the mixture airy and light.
Step 8: Chill the Mousse
Divide the mousse evenly into serving dishes or ramekins. Refrigerate for at least 2 hours to allow the flavors to meld and the mousse to set into a beautiful, creamy delight.
How to Serve Decadent Chocolate Mousse Recipe

Garnishes
The simplest garnishes can elevate this dessert. A swirl of fresh whipped cream topped with delicate chocolate shavings or curls adds elegance and texture contrast. Fresh berries or a dusting of cocoa powder are also fantastic for brightening up the intense chocolate flavors.
Side Dishes
This mousse pairs wonderfully with crisp, fresh notes to balance its richness. Consider serving alongside fresh raspberries, a tart fruit compote, or even crunchy biscotti for a delightful bite contrast.
Creative Ways to Present
Presentation can be part of the fun. Try layering the mousse in clear glasses with alternating layers of crushed cookies or nuts for a parfait style. Using edible flowers or gold leaf can add a stunning touch if you’re entertaining. Even a dusting of chili powder or espresso powder on top can provide an unexpected flavor kick.
Make Ahead and Storage
Storing Leftovers
Any leftover mousse should be covered tightly with plastic wrap or stored in airtight containers and kept in the refrigerator. It will keep beautifully for up to 2 days, preserving its creamy texture and rich taste.
Freezing
While chocolate mousse can be frozen, the texture might change slightly upon thawing, becoming a little grainy. If you decide to freeze it, do so in airtight containers and thaw slowly overnight in the refrigerator for best results.
Reheating
This dessert is best enjoyed cold straight from the fridge. Reheating is not recommended, as it will melt the mousse’s delicate structure and alter the texture dramatically.
FAQs
Can I use milk chocolate instead of dark chocolate for this Decadent Chocolate Mousse Recipe?
Yes, you can substitute milk chocolate, but keep in mind this will result in a sweeter and less intense chocolate flavor. If you prefer a richer taste, 70% dark chocolate is ideal.
Is it safe to eat mousse made with raw eggs?
Using fresh, high-quality eggs reduces risk, but if you have concerns, you can look for pasteurized eggs or use a recipe that cooks the eggs. This traditional mousse includes raw eggs, so make sure to take appropriate precautions.
How long does it take to make this Decadent Chocolate Mousse Recipe?
The active prep time is about 20 minutes, but it requires at least 2 hours chilling time to set properly. Planning ahead makes the process stress-free and worth every minute of waiting.
Can I make this mousse vegan or dairy-free?
To adapt this recipe for vegan needs, you’d need to substitute the eggs and dairy cream with alternatives like aquafaba for the whites and coconut cream for whipping. The chocolate selected should also be dairy-free.
Why is my mousse not setting properly?
Common causes include overwhipping, folding too vigorously which deflates the mixture, or chocolate that was too hot when combined. Ensure all ingredients are at the right temperature and folded gently to keep the mousse airy.
