This guide walks you through everything you need to know, from choosing the right chocolate to mastering the fluffy texture and picking creative toppings. So whether you're hosting a large event or just want a special dessert for your next get together, you’ll find all the techniques here to help you whip up mousse cups like a pro.

Ingredients:

• 200 g dark chocolate (preferably 60–70% cocoa)
• 1 cup heavy cream (plus extra for whipping)
• 3 eggs, separated
• 2 tbsp granulated sugar
• A pinch of salt
• 1 tsp vanilla extract (optional)

Method:

1. Break the dark chocolate into pieces and melt it gently using a double boiler or in the microwave. If using a microwave, heat in short 20 second bursts, stirring in between to avoid scorching. Once smooth and glossy, set it aside to cool slightly. It should be warm, not hot, when added to the rest of the mixture.
2. In a chilled bowl, whip 1 cup of heavy cream until soft peaks form. Don't overwhip. It should hold its shape but still look smooth and glossy. Place it in the fridge while you prep the rest.
3. Using a clean, dry bowl and beaters, whip the egg whites with a pinch of salt until they turn frothy. Gradually add the sugar and continue beating until you get firm, glossy peaks. The stiffer the peaks, the lighter your mousse will be.
4. Stir the egg yolks into the slightly cooled melted chocolate. This creates a rich, velvety base. Gently fold in the whipped cream using a spatula. Do this in batches, being careful not to deflate the mixture. Lastly, fold in the beaten egg whites in two parts. Use a gentle, lifting motion to keep the mousse airy. At this point, your mousse should be smooth, fluffy, and chocolatey with a luxurious texture.
5. To elevate your mousse, layer them with other flavors. Add a thin layer of raspberry compote, orange curd, or espresso jelly before spooning in the mousse. The added contrast in flavor and color makes it even more impressive. Here are some other flavor variations you can try:
6. Infuse the cream with fresh mint leaves by warming them together and letting it steep before chilling and whipping. Or add a few drops of mint extract to the mousse base.
7. Add a pinch of cinnamon, cayenne, or chili powder to the melted chocolate. It brings a subtle warmth and depth, perfect for winter parties.
8. Before spooning mousse into the cups, pour a spoonful of salted caramel sauce into the bottom. It creates a sticky, sweet surprise at the base of each serving.
9. Add 1 tablespoon of espresso or strong coffee to the melted chocolate. Coffee enhances the chocolate flavor and gives the mousse a refined edge.
10. Spoon the mousse into individual cups or dessert glasses. Small ramekins, shot glasses, or mini jars also work beautifully. For a classy look, use cocktail glasses, coupe glasses, or even espresso cups. Layering mousse in clear glasses also lets your guests admire the texture and toppings.
11. Once portioned, cover them loosely with cling film and refrigerate for at least 4 hours, or ideally overnight. The mousse firms up while chilling, creating that melt in your mouth texture.
12. Right before serving, add toppings like:
    • Whipped cream
    • Chocolate shavings or curls
    • Cocoa powder or icing sugar dusting
    • Crushed nuts (hazelnuts, pistachios, almonds)
    • Fresh berries or citrus zest
    • Edible gold flakes or glitter for extra glam
13. Mousse can be made up to 2 days in advance and stored in the fridge, making it ideal for busy party prep. Always store mousse covered, especially if you’re not serving it in lidded jars, to prevent it from absorbing fridge odors. If you’re topping with fresh fruit or whipped cream, add those just before serving to maintain freshness and texture. Leftovers will keep in the fridge for up to 3 days.
