There’s something about Julia Child’s recipes that feels like a warm hug from your favorite aunt. You know, the one who greets you with a bear hug, a kitchen full of mouth-watering smells, and a dessert that leaves you practically licking the plate. That’s how I feel every time I make her classic chocolate mousse. And the best part? It’s not even that hard to make.
I first stumbled upon Julia Child’s chocolate mousse recipe during a late-night binge of The French Chef reruns. You know, those days when you’re curled up on the couch, craving something sweet but far too lazy to actually bake anything. As Julia worked her magic, whisking eggs and melting chocolate with the kind of passion that made you believe you could do it, too, I was hooked. But here’s the twist—I’m not exactly Julia Child in the kitchen. My cooking style is more like, “throw things in a bowl and hope for the best.” Yet, somehow, her recipe spoke to me. It was rich, velvety, and looked like pure decadence. So, I decided to give it a shot.

The first time I made it, I was a hot mess. Chocolate everywhere, bowls piling up in the sink, and me, frantically whisking egg yolks like my life depended on it. But when I took that first spoonful of creamy, chocolatey goodness, it was like I had unlocked some kind of culinary superpower. It was everything you want a dessert to be—smooth, rich, and completely irresistible. Fast forward to today, and I’ve made this mousse more times than I can count. I’ve even managed to put my own spin on it, tweaking a few things here and there, but always staying true to the luscious, dreamy dessert that Julia intended.

Cooking Instructions: How to Make Julia Child’s Chocolate Mousse Dish

- Melt the Chocolate and Butter
Combine the chopped chocolate, coffee, and butter in a heatproof bowl. Place it over a pot of simmering water (double boiler style) and stir until everything is smooth and melted. Remove from heat and let it cool slightly. - Whisk the Egg Yolks and Sugar
In another bowl, whisk the egg yolks with half of the sugar (1/4 cup) until the mixture is pale and creamy. Gradually add the melted chocolate mixture and mix until smooth. Add the vanilla extract and stir well. - Beat the Egg Whites
In a clean bowl, beat the egg whites with a pinch of salt until they form soft peaks. Slowly add the remaining sugar and continue beating until stiff peaks form. - Whip the Cream
In a separate bowl, whip the heavy cream until it forms soft peaks. Set aside. - Fold Everything Together
Gently fold the whipped cream into the chocolate mixture until partially combined. Then, fold in the beaten egg whites until the mixture is smooth and glossy. - Chill and Serve
Spoon the mousse into serving glasses or dishes and refrigerate for at least 2 hours. Serve chilled and enjoy!

This mousse keeps well in the fridge for up to three days. Just cover it with plastic wrap to keep it fresh. - Use Good Chocolate
Since chocolate is the star of the show, go for high-quality chocolate with at least 70% cocoa. It makes all the difference. - Serving Suggestions
Pair this mousse with shortbread cookies or enjoy it on its own. Either way, it’s pure chocolate bliss.

Want to add some flair? Mix in a dash of orange liqueur or espresso powder for extra richness. - Presentation Matters
Serve your mousse in pretty glasses or jars and top with whipped cream, shaved chocolate, or fresh berries for a fancy touch.
