This Classic Chocolate Mousse recipe takes 3 hours 20 min and makes 6 servings, with a 3-hour chill doing most of the work. Bittersweet chocolate is melted with butter, then whisked into egg yolks for body, while cold heavy cream and separately whipped egg whites supply the air.

Instructions
Melt the chocolate and butter in a heatproof bowl set over barely simmering water, stirring until smooth, then pull the bowl off and let it cool about 10 minutes to lukewarm. Chocolate hotter than 110 degrees F cooks the yolks the moment they touch it.
Whisk the egg yolks into the cooled chocolate one at a time until the mixture is thick and glossy, then stir in the vanilla. Adding them one at a time keeps the emulsion smooth instead of seizing.
Whip the cold cream in a chilled bowl to soft peaks, about 2 minutes, and hold it in the refrigerator. Cold cream whips faster, and soft peaks fold in without deflating the base.
Beat the egg whites with the salt on medium speed until foamy, add the sugar in three additions, and beat to soft, glossy peaks. Stop at soft peaks, because dry whites break into lumps that never fold back in.
Stir one third of the whipped cream into the chocolate to loosen it, then fold in the remaining cream and all of the whites in three additions with a rubber spatula. Working in thirds keeps the air you just built.
Spoon the mousse into six glasses, press plastic wrap onto the surface, and refrigerate at least 3 hours until set. A chill, not a freeze, gives the creamy set that freezing ruins.
Top with lightly whipped cream and chocolate shavings just before serving, and keep the glasses cold until they go out to the table.
Troubleshooting — fixes, not repeats
- If the mousse is grainy, the chocolate was too warm for the yolks or a drop of water reached the melted chocolate. Cool the base to lukewarm, add the yolks one at a time, and keep every utensil dry.
- If it is dense and flat, the cream or the whites were overwhipped, or the mixtures were stirred instead of folded. Stop both at soft peaks and fold in three additions with a spatula.
- If it does not set, the chill was too short or the cream was underwhipped. Give it 4 hours, keep the glasses covered, and set them in the coldest part of the refrigerator.
- If the surface looks dull and separated, the mousse sat out too long. Keep it covered and cold, and press plastic wrap to the surface to stop a skin from forming.
Make it your way
- Old Dhaka style: An egg-free version folds the whipped cream into the chocolate base alone, adds 1 tablespoon of melted butter for softness, and chills at least 4 hours.
- For a milk chocolate version, use 6 ounces of milk chocolate and cut the sugar to 2 tablespoons, since milk chocolate is already sweet.
- A mocha batch stirs 1 teaspoon of espresso powder into the melted chocolate.
- For a bittersweet orange mousse, rub 1 teaspoon of orange zest into the sugar before it goes into the whites.
Storage & reheating
Cool leftovers within 2 hours, then refrigerate in a covered container and use within 3 to 4 days. Reheat only the portion you will eat until steaming hot throughout — poultry and reheated rice should reach 165°F (74°C).
Freezing changes the texture and makes the mousse slightly grainy, so chilling is the better route.
FAQ
Can I make chocolate mousse without raw eggs?
Yes. Warm the yolks with 2 tablespoons of sugar over a double boiler, whisking, until they reach 160 degrees F, then cool them before folding, or use pasteurized eggs. Children, older adults, and anyone pregnant or immunocompromised should have the cooked version.
Why did my mousse seize?
A drop of water or a cold utensil touching melted chocolate stiffens it into a grainy mass. Start over with dry tools, or whisk 1 teaspoon of hot water or melted butter into the seized bowl to bring it back.
How far ahead can I make it?
Make the mousse up to 2 days ahead and keep it covered and cold. Leave the toppings off until serving. For a party, portion it into glasses ahead so guests can take one without slicing.
