Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the mousse

Bittersweet chocolate – I use 70-74% cocoa for that intense, rich flavor
Eggs – Separated; yolks add creaminess, whites create the mousse’s light texture
Granulated sugar – Balances the bitterness of the chocolate
Butter – Adds silkiness and richness
Orange liqueur (optional) – Offers a subtle citrus brightness

For Chantilly cream (optional)

Heavy cream – Whips into a soft, luscious topping
Powdered sugar – Adds gentle sweetness
Vanilla extract – Gives a deeper, aromatic flavor

Directions

Melt the chocolate and butter: I gently melt them together over a double boiler, stirring until smooth. Then, I let it cool slightly.
Whip the yolks: I whisk the egg yolks with half the sugar until they become pale and creamy.
Combine yolks and chocolate: I slowly add the cooled chocolate mixture into the yolks and fold gently to avoid deflating the mixture.
Whip the egg whites: In a clean bowl, I beat the whites to soft peaks, add the rest of the sugar, and whip until stiff peaks form.
Fold the whites into the chocolate: I start with a small portion of egg whites to lighten the chocolate base, then fold in the rest in two additions.
Chill: I spoon the mousse into serving glasses or ramekins and chill it for at least 4 hours—or overnight—for the best texture and flavor.
Top with Chantilly cream (optional): Before serving, I add a generous dollop for extra indulgence.

Variations

Dairy-free: I swap the chocolate and butter for dairy-free versions and use coconut cream instead of Chantilly.
Nutty addition: I mix in finely ground hazelnuts or almonds for a subtle crunch and nutty taste.
Mint twist: A few drops of peppermint extract give it a cool, fresh layer of flavor.
Spicy flair: A tiny pinch of cayenne or chili powder gives the mousse a warm, unexpected edge.
Fruit boost: I sometimes fold in raspberries or chopped strawberries for a tart contrast.
Espresso-enhanced: A dash of espresso or coffee deepens the chocolate’s intensity.
Citrus boost: Orange zest adds a fresh zing that complements the liqueur beautifully.
Crunchy base: Crushed cookies at the bottom of the serving glass add texture and contrast.

Storage/Reheating

Fridge: I keep the mousse chilled in the fridge for up to 3 days, covered tightly with plastic wrap to retain its freshness.
Freezer: While I prefer it fresh, I can freeze it for up to 1 month in an airtight container. The texture softens slightly once thawed.
Reheating: No reheating needed—this dessert is best served cold right from the fridge.

FAQs

What type of chocolate should I use for the mousse?

I always go for bittersweet chocolate with 70–74% cocoa. It delivers the perfect rich flavor that isn’t too sweet and gives a wonderfully smooth consistency.

Can I make this mousse ahead of time?

Definitely. I usually prepare it the night before an event—it gives the mousse time to set and the flavors to deepen, making it even better the next day.

How do I know if I’ve whipped the egg whites correctly?

When I lift the whisk, the peaks should stand up firmly without drooping. Also, the bowl should be grease-free—any fat can prevent proper whipping.

Is it okay to skip the orange liqueur?

Of course. I sometimes use orange extract for a non-alcoholic version or skip it entirely if I want a more classic chocolate flavor.

Can I make a vegan version of this mousse?

Yes, I replace the eggs with aquafaba (chickpea brine) for whipping and use vegan chocolate and butter substitutes. It takes a bit of practice, but it works beautifully.

Conclusion

Every spoonful of this chocolate mousse delivers pure satisfaction. It’s the kind of dessert I turn to when I want to treat myself or impress someone special. With just a few quality ingredients and a bit of patience, I end up with a show-stopping treat that’s light, rich, and elegant. Whether I stick to the classic version or experiment with fun variations, this recipe always finds its way back into my kitchen.
