What Ingredients You Will Need

This decadent chocolate hazelnut mousse recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without fuss. Most of these are pantry staples, with a couple fresh touches that really make the difference.

• Dark chocolate (70% cacao or higher), chopped: For that rich, bittersweet base (I love using Valrhona or Ghirardelli for best results).
• Heavy cream (cold): The secret to that silky, smooth mousse texture.
• Hazelnut spread (like Nutella): Adds a luscious, nutty flavor that blends perfectly with the chocolate.
• Egg whites (large, room temperature): Whipped to stiff peaks to keep the mousse light and airy.
• Granulated sugar: Just a touch to balance bitterness and sweeten the egg whites.
• Vanilla extract: For a subtle fragrant note.
• Whole hazelnuts: Toasted and roughly chopped for that irresistible crunchy topping.
• Pinch of salt: To enhance all the flavors.

Substitution tips: Use coconut cream instead of heavy cream for a dairy-free version, and swap hazelnut spread with almond butter if you’re allergic. For a gluten-free dessert, this recipe is naturally safe, so no worries there.

Equipment Needed

• Mixing bowls: Several sizes, preferably glass or stainless steel for whipping cream and egg whites.
• Electric mixer or stand mixer: A lifesaver for whipping egg whites and cream quickly and to the perfect consistency.
• Spatula: For gentle folding to keep the mousse airy.
• Small saucepan: To melt your chocolate gently over a double boiler or low heat.
• Baking sheet or pan: To toast the hazelnuts evenly in the oven.
• Serving cups or ramekins: For portioning your mousse cups—anything from pretty glassware to simple jars works.

If you don’t have a stand mixer, no worries—an electric hand mixer works just fine. For toasting nuts, a simple oven sheet lined with parchment paper makes cleanup a breeze. I’ve found that investing in a good silicone spatula is worth it for folding delicate mixtures without deflating them. Budget-friendly options are easily available at most kitchen stores.

Preparation Method

1. Toast the hazelnuts (10 minutes): Preheat your oven to 350°F (175°C). Spread the whole hazelnuts evenly on a baking sheet and roast for 8–10 minutes until fragrant and golden brown. Let cool, then rub them in a clean kitchen towel to remove most of the skins. Roughly chop and set aside for topping.
2. Melt the chocolate (5 minutes): Place chopped dark chocolate in a heatproof bowl over simmering water (double boiler method). Stir gently until smooth. Remove from heat and let cool slightly, but do not let it set.
3. Whip the cream (5 minutes): In a chilled mixing bowl, beat the cold heavy cream until soft peaks form. Be careful not to overbeat—you want it light and fluffy, not grainy.
4. Prepare the egg whites (5 minutes): In a separate bowl, beat the room-temperature egg whites with a pinch of salt until foamy. Gradually add granulated sugar, then continue beating until stiff peaks form (the peaks should stand straight when you lift the beaters).
5. Combine hazelnut spread and melted chocolate (2 minutes): Gently stir in the hazelnut spread and vanilla extract into the melted chocolate until fully incorporated and smooth.
6. Fold in whipped cream (3 minutes): Add about one-third of the whipped cream to the chocolate mixture and fold gently using a spatula. This lightens the chocolate base. Then fold in the remaining cream carefully to keep the mousse airy.
7. Incorporate egg whites (3 minutes): Fold the whipped egg whites into the mousse mixture in two additions. Use a gentle folding motion to maintain volume—don’t rush this step, or you’ll lose the fluffy texture.
8. Portion the mousse (5 minutes): Spoon the mousse into your serving cups or ramekins evenly. Smooth the tops with the back of a spoon.
9. Add the crunchy topping (2 minutes): Sprinkle the toasted, chopped hazelnuts generously over each mousse cup.
10. Chill and set (at least 2 hours): Refrigerate the mousse cups until firm and chilled through. They taste best when served cold but not frozen.

If your chocolate seizes or looks grainy, add a teaspoon of warm cream to smooth it out before folding in the rest. If the mousse looks too loose after folding, check that your egg whites were whipped to stiff peaks—this step is key! Also, I like to prep this in the morning and let it chill all afternoon for the best texture.

Cooking Tips & Techniques

There’s a bit of finesse in making mousse, but once you get the hang of it, you’ll see why it’s such a classic. One trick is to make sure your egg whites are completely free of any grease or yolk before whipping; even a tiny bit can prevent them from reaching stiff peaks. Also, chilling your mixing bowls ahead makes whipping cream much easier and faster.

When folding, use a spatula to scoop from the bottom and gently turn over the mixture, rather than stirring vigorously. This keeps the mousse light and fluffy. I learned this the hard way after ending up with a dense pudding instead of airy mousse. Timing matters too—don’t rush the chilling process. Letting the mousse set fully in the fridge gives it that perfect silky texture.

Another pro tip: toast your hazelnuts just until fragrant, not burnt, because that can add bitterness. And if you want to save time, pre-chopped toasted nuts from a trusted brand can work, but freshly toasted ones taste noticeably better. Lastly, if you want a richer flavor, use a chocolate with at least 70% cacao; it balances sweetness beautifully.

Variations & Adaptations

This decadent chocolate hazelnut mousse recipe is pretty versatile, so you can tweak it based on your mood or dietary needs.

• Seasonal Twist: Swap hazelnuts for toasted pecans or walnuts in fall for a cozy, nutty flavor. Adding a pinch of cinnamon or orange zest to the mousse can also brighten it up.
• Dairy-Free Version: Use coconut cream instead of heavy cream and a dairy-free chocolate to make this vegan-friendly. You can also replace egg whites with aquafaba (the liquid from canned chickpeas) whipped to stiff peaks.
• Extra Crunch: For a textural surprise, layer the mousse with crushed hazelnut praline or chocolate wafer cookies in between.
• Adult Version: Add a splash of hazelnut liqueur or coffee liqueur to the chocolate mixture for a grown-up kick.
• Personal Favorite: I once stirred in a bit of espresso powder with the chocolate—it gave the mousse a subtle mocha flavor that had everyone asking for seconds.

Serving & Storage Suggestions

Serve these chocolate hazelnut mousse cups chilled for that perfect creamy texture. A garnish of fresh mint leaves or a dusting of cocoa powder elevates the presentation without fuss. They pair beautifully with a cup of strong coffee or a glass of dessert wine if you’re feeling fancy.

If you’re prepping ahead, store the mousse cups covered in the fridge for up to 3 days. Avoid freezing as it can change the texture and make it grainy. When reheating chocolate is involved, this dessert is truly best fresh or chilled.

Leftovers? No problem. Just let them sit out at room temperature for 10 minutes before serving to let the flavors bloom. Honestly, the mousse tastes even better the next day as the chocolate and hazelnut flavors deepen and meld together.
