2-Ingredient Chocolate Mousse Cups

I used to think real chocolate mousse was a restaurant-only dessert, until I learned you can make a silky, airy version at home with just two ingredients. Chocolate and heavy cream, a whisk, and a little patience while it chills, and you have little cups of pure chocolate happiness.

There are no raw eggs and no gelatin, so it is simple and safe for everyone. Below you will find the full recipe, step-by-step photos, tips for the smoothest texture, fun toppings, and storage notes.

Ingredients

For the Mousse

• 1 cup (6 ounces) semi-sweet chocolate chips or chopped chocolate
• 1 1/2 cups cold heavy whipping cream, divided

Optional Toppings

• Whipped cream
• Chocolate shavings or cocoa powder
• Fresh raspberries or strawberries
• A pinch of flaky sea salt

Ingredient Notes

• Chocolate: semi-sweet gives a classic flavor; use bittersweet for a darker mousse or milk chocolate for a sweeter one.
• Heavy cream: it must be very cold to whip properly, so keep it in the fridge until the last minute.
• Temperature matters: the melted chocolate needs to cool to room temperature before folding, or it will melt the whipped cream.

How to Make 2-Ingredient Chocolate Mousse

1. Melt the chocolate. Heat 1/2 cup of the cream until it just steams. Pour it over the chocolate chips in a bowl, wait 2 minutes, then stir until completely smooth and glossy.
2. Cool it down. Let the chocolate mixture cool to room temperature, about 10 minutes, stirring now and then. It should feel neutral to the touch.
3. Whip the cream. Beat the remaining 1 cup cold cream to soft, pillowy peaks.
4. Lighten the chocolate. Stir about one-third of the whipped cream into the chocolate to loosen it.
5. Fold. Gently fold in the rest of the whipped cream until no white streaks remain. Use slow, sweeping folds so it stays airy.
6. Fill and chill. Spoon or pipe the mousse into small glasses or cups and refrigerate for at least 2 hours, until set.
7. Top and serve. Add whipped cream, chocolate shavings, berries, or a pinch of sea salt right before serving.

Tips for the Silkiest Mousse

• Do not overwhip the cream. Soft peaks fold in more smoothly than stiff ones.
• Cool the chocolate fully. Warm chocolate deflates the cream and makes the mousse runny.
• Fold gently. Stirring hard knocks out the air.
• Use good chocolate. With only two ingredients, the chocolate flavor is everything.

Easy Variations

• Mocha: dissolve 1 teaspoon instant espresso in the warm cream.
• Orange chocolate: add a little orange zest to the melted chocolate.
• White chocolate: use white chocolate chips and top with berries.
• Peanut butter swirl: swirl a spoonful of warmed peanut butter into each cup.

Storage

• Refrigerator: cover the cups and keep for up to 3 days.
• Freezer: freeze for up to 1 month for a frozen, ice cream-like treat; thaw 10 minutes before eating.
• Serving: add toppings just before serving so they stay fresh.

Frequently Asked Questions

Why is my mousse grainy?

The chocolate was likely too cold or too hot when combined. Make sure the ganache is smooth and at room temperature before folding.

Can I use cocoa powder instead of chocolate chips?

This recipe needs real chocolate for its structure; cocoa powder alone will not set the same way.

Can I make it dairy-free?

Use chilled full-fat coconut cream and dairy-free chocolate; the texture will be slightly denser.

How far ahead can I make it?

Up to 2 days ahead. Add toppings the day you serve it.
