Single Serving Chocolate Mousse: A Classic Indulgence

Chocolate mousse is a luxurious French dessert known for its heavenly texture – it’s light and airy, but still incredibly rich. The word “mousse” means “foam” in French, highlighting its airy quality. This single serving recipe uses the traditional method of incorporating an egg, ensuring a silky, velvety texture that makes it a true classic. It’s the perfect way to treat yourself!

Ingredients

If you have any ingredients leftover from this small batch chocolate mousse recipe, check out our Leftover Ingredients Recipe Finder.

  • Chocolate: I like to use semi-sweet chocolate, commonly found in the baking aisle. Brands like Ghirardelli, Lindt, or Baker’s are recommended. If you prefer a bolder taste, dark chocolate is a great alternative. Consider using leftover chocolate in a mini French Silk Pie and Chocolate Pudding.
  • Butter: I use salted butter for this recipe.
  • Egg: One large egg is essential. It’s the secret to the mousse’s light, fluffy, and rich texture. For safety, use pasteurized eggs, especially recommended for pregnant women and young children who should avoid raw eggs.
  • Cream of tartar: This ingredient helps in thickening the cream effectively.
  • Sugar: Feel free to reduce the quantity for a less sweet taste.
  • Heavy cream: Also known as double cream, it adds richness to the mousse. If you’ve got extra cream, use it in a mini German Chocolate Cake, Honey Lemon Custard, or Panna Cotta.
  • Vanilla extract: A dash of vanilla extract enhances the overall flavor of the mousse.

How To Make Chocolate Mousse For One

See the recipe box below for ingredient amounts and full recipe instructions.

  1. Melting Chocolate: Begin by melting 3 ounces of semi-sweet chocolate and butter in a double boiler over gently simmering water. Once melted, remove from heat and allow it to cool. After cooling for a few minutes, whisk in an egg yolk.
  2. Whipping Egg Whites: In a separate bowl, beat the egg white. Add cream of tartar and sugar, then continue beating until stiff peaks form.
  3. Making Whipped Cream: In another bowl, combine heavy cream, sugar, and vanilla extract to create whipped cream.
  4. Combining Ingredients: Carefully fold the melted chocolate, whipped egg whites, and whipped cream together until well blended.
  5. Chilling: Pour the mixture into a dessert dish and refrigerate for a minimum of 3 hours.

Although this classic chocolate mousse recipe involves several steps and takes some time, the delicious result is definitely worth the effort!

Expert Tips

  • Separate with Care: Use clean, dry bowls to separate the egg white. Even a trace of yolk can prevent it from whipping fully.
  • Melt Gently: Heat the chocolate slowly in a double boiler or microwave on low power, stirring frequently, to avoid burning or seizing.
  • Fold Like a Feather: Gently incorporate the melted chocolate and whipped cream into the egg yolk mixture with a spatula. Overmixing can deflate the air and leave you with a dense mousse.
  • Chilling Time: Let the mousse set in the fridge for optimal flavor and consistency.

How To Serve Chocolate Mousse

  • Top with Whipped Cream: A classic addition for extra richness.
  • Garnish with Berries: Fresh berries add a delightful contrast.
  • Sprinkle with Cocoa: For a deeper chocolate flavor.

Frequently Asked Questions

What sets chocolate mousse apart from chocolate pudding?

While both desserts are similar, they have distinct differences.
Pudding typically involves milk or cream, sugar, and is thickened with cornstarch, resulting in a creamy texture. There are various methods to prepare it, but this combination is traditional.
On the other hand, mousse boasts a lighter and fluffier texture. This is achieved by folding whipped egg whites and whipped cream into the mixture. Unlike pudding, mousse is made without cornstarch, which contributes to its airy consistency.

Can I make chocolate mousse in advance?

Yes, it’s perfect for preparing a day ahead.

How long does chocolate mousse keep?

Store in the fridge for up to 2 days.

Can I make chocolate mousse for two?

Absolutely, just double the ingredient amounts.

    Is there anything else I can use in place of cream of tartar?

      I haven’t tested this recipe with anything other than cream of tartar. It really is a necessary ingredient.
