Ingredient Breakdown

• 200g Dark chocolate (70% cocoa or higher): The star of the show, providing deep cocoa richness. You can substitute with semi-sweet chocolate but expect a sweeter, less intense flavor.
• 300ml Heavy cream: Whipped to soft peaks, this creates the mousse’s airy silkiness. For a lighter version, you could try half-and-half but don’t expect the same velvet texture.
• 100g Toasted hazelnuts (chopped): Adds warmth and crunch. Try almonds or pistachios for a different nutty twist.
• 3 Large egg whites: Whipped into stiff peaks, they lighten and lift the mousse. Always use fresh eggs for best volume and food safety.
• 50g Granulated sugar: Stabilizes the egg whites and adds gentle sweetness. You can swap for superfine sugar for quicker dissolving or a natural sweetener like erythritol in small amounts.

Before You Begin

Getting started is all about setting yourself up for smooth success. Gather and measure ingredients (mise en place) so you’re not scrambling mid-recipe. Toast the hazelnuts ahead of time to develop those golden flavors, ideally in a 180°C / 350°F oven for 8-10 minutes, stirring halfway. Also, chill your mixing bowl and beaters for the cream — a little cold helps the cream whip up faster and fluffier.

• A heatproof bowl and saucepan for the chocolate melting double boiler method.
• Electric mixer or sturdy whisk to whip cream and egg whites effectively.
• Spatula for gentle folding to keep that airy texture intact.
• Toaster oven or skillet for prepping the hazelnuts.
• Serving dishes or ramekins for chilling your mousse in pretty portions.

How to Make Chocolate Hazelnut Mousse Recipe

1. Melt the dark chocolate gently in a heatproof bowl set over simmering water, stirring until it’s completely smooth and glossy. You’ll smell that rich cocoa aroma begin to bloom — a good sign you’re on the right track.
2. Whip the heavy cream in a chilled bowl until soft peaks form. It should have a silky texture that holds shape but still folds gently.
3. Beat the egg whites in a clean bowl until frothy. Gradually add the granulated sugar, then continue whipping until you reach stiff, glossy peaks. The mixture should stand up firmly without sliding when you lift the whisk.
4. Fold the melted chocolate gently into the whipped cream, using slow, sweeping motions with a spatula. This keeps the mousse light and airy without deflating it.
5. Carefully fold in the beaten egg whites in two batches, being even more gentle to keep the volume intact. A soft, fluffy texture is the goal here.

Pro-Level Pointers

Be sure your mixing bowls and tools are completely clean and free of any fat or yolks — they interfere with egg whites reaching full volume. When folding, use a light hand; imagine gently circling around the bowl to keep those airy bubbles from bursting.

Also, avoid over-melting your chocolate — it should be warm but not hot, otherwise it can seize or tighten the mousse texture.

The toasted hazelnuts add a fresh, slightly caramelized crunch. If you prefer a finer texture, pulse them briefly in a food processor before folding in.

6. Add the chopped toasted hazelnuts and mix gently just until dispersed.
7. Spoon the mousse into your serving dishes and refrigerate for at least two hours, ideally longer if you can wait. The cooler temperature helps the mousse set into that silky, melt-in-your-mouth consistency you’ll love.

Creative Variations for Chocolate Hazelnut Mousse Recipe

• Espresso infusion: Stir a teaspoon of instant espresso powder into the melted chocolate for a mocha twist.
• Orange zest: Add finely grated orange peel to the whipped cream for a bright, citrusy aroma that cuts through the rich chocolate.
• Spiced warmth: Mix in a pinch of cinnamon or chili powder to the chocolate for a subtle, warming heat that surprises.
• Nutty swaps: Replace hazelnuts with toasted pecans or pistachios for a unique crunch and flavor profile.
• Layered parfait: Alternate mousse layers with crushed biscotti or cookie crumbs for a textural contrast.
• Whipped topping: Garnish with a dollop of lightly sweetened whipped cream and extra toasted nuts right before serving.

Storage, Freezing & Reheating

• Refrigerate: Store in airtight containers for up to 3 days. The mousse holds its texture beautifully but enjoy it fresh for best fluffiness.
• Freeze: This mousse can be frozen for up to 2 months in tightly sealed containers. Thaw overnight in the fridge before serving.
• Do not reheat: Chocolate mousse tastes best cold; reheating will change the texture.
• Make ahead: Prepare a day or two in advance to let flavors deepen — just keep chilled.

Chocolate Hazelnut Mousse Recipe FAQs

• Can I use milk chocolate instead of dark? You can, but your mousse will be sweeter and less intense. Adjust sugar accordingly to balance.
• Is it safe to use raw egg whites? Fresh eggs from a trusted source are best. If concerned, look for pasteurized egg whites or substitute with aquafaba (chickpea water) whipped similarly.
• How do I know when the egg whites are at stiff peaks? Lift the whisk carefully; the peaks should stand straight up without folding over or drooping.
• Can I make this dairy-free? Try coconut cream whipped in place of heavy cream and check chocolate labels for dairy-free options. Texture will vary but still delicious.
• What’s the best way to toast hazelnuts? Spread them on a baking sheet and roast at 180°C / 350°F for about 8-10 minutes, stirring once. Let cool before chopping.
