Ingredients You’ll Need
The beauty of making this Chocolate Hazelnut Dome with Praline Crunch lies in its simple yet thoughtful selection of ingredients. Each component adds a layer of flavor and texture that’s essential to the final masterpiece.
- Praline paste: This sweet, nutty base is key for that signature hazelnut crunchy center.
- Crushed hazelnuts: Adding an extra bite and toasty flavor to the praline insert.
- Dark chocolate (8 oz): Choose a high-quality chocolate for a deep, rich mousse flavor.
- Heavy cream (1 cup): Whipped to fluffy perfection, it gives the mousse its light, airy texture.
- Vanilla (1 teaspoon): A subtle touch to enhance all the chocolate and hazelnut notes.
- Mirror glaze or cocoa butter spray: For that stunning, glossy finish that will wow your guests.
- Chopped hazelnuts: To decorate and add a rustic crunch to the finished domes.
How to Make Chocolate Hazelnut Dome with Praline Crunch
Step 1: Prepare the Praline Crunch Insert
Start by combining the praline paste with the crushed hazelnuts until well mixed. Spoon this mixture into small rounds, ideally using silicone molds or a parchment-lined tray, and pop them into the freezer. This step ensures your crunchy core retains its shape and texture when surrounded by luscious mousse later.
Step 2: Create the Silky Chocolate Mousse
Melt the dark chocolate carefully, either over a double boiler or in short bursts in the microwave, stirring consistently to avoid burning. Meanwhile, whip your heavy cream with the vanilla until soft peaks form. Gently fold the whipped cream into the melted chocolate in batches, taking care to maintain that airy texture crucial for a melt-in-your-mouth mousse.
Step 3: Assemble the Domes
Fill your dome molds about halfway with the mousse. Press a frozen praline crunch insert into the center of each, then cover completely with the remaining mousse. Smooth the top and freeze the domes for at least four hours until fully set. This chilling period is essential for achieving that perfect slice and shape when unmolding.
Step 4: Unmold and Apply the Finishing Touches
Once frozen solid, gently unmold each dome. Quickly coat with a glossy mirror glaze or a delicate cocoa butter spray to give it that luxurious, reflective surface. Finally, sprinkle chopped hazelnuts over the top for a beautiful, textural contrast that invites you to dig in.
How to Serve Chocolate Hazelnut Dome with Praline Crunch

Garnishes
Simple garnishes can elevate this dessert even further. A dusting of cocoa powder, a few whole toasted hazelnuts, or even a drizzle of caramel sauce complements the chocolate and nut flavors without overpowering the elegant dome.
Side Dishes
Serve alongside fresh berries or a light fruit coulis to cut through the richness. A small scoop of vanilla bean ice cream or a dollop of whipped cream can also add a creamy counterpoint that’s delightful with the crunchy center.
Creative Ways to Present
For a dinner party, present the Chocolate Hazelnut Dome with Praline Crunch on individual dessert plates garnished with edible flowers or gold leaf for that extra wow factor. You can also place the domes on a bed of finely crushed biscotti or cookie crumbs for added drama and flavor harmony.
Make Ahead and Storage
Storing Leftovers
If you manage to have leftovers, keep the domes tightly covered in an airtight container in the refrigerator. They’ll maintain their texture and flavor for up to two days without any loss in quality.
Freezing
This dessert freezes beautifully. Once assembled and frozen solid, store the domes in a sealed container or wrap them individually. They’ll keep for up to two weeks in the freezer, making them perfect to prepare ahead of time for special occasions.
Reheating
Since this is a chilled mousse dessert, reheating isn’t recommended. Instead, let frozen domes thaw in the refrigerator for a few hours before serving to keep their ideal texture and taste.
FAQs
Can I use other nuts instead of hazelnuts for the praline crunch?
Absolutely! Almonds, pecans, or pistachios can all work wonderfully, each bringing their own unique flavor and crunch to the dome.
What if I don’t have a mirror glaze? Can I use something else?
You can substitute with a cocoa butter spray or lightly dust the domes with cocoa powder for a more rustic but still elegant finish.
How long does it take to make the Chocolate Hazelnut Dome with Praline Crunch?
Preparing this dessert takes about 1 hour, but keep in mind you’ll need to freeze the domes for at least 4 hours to set properly.
Can I make the mousse ahead of time?
Yes, you can prepare the mousse a day in advance and keep it refrigerated, but be sure to gently fold it before assembling to maintain its texture.
Is it possible to make this dessert vegan or dairy-free?
To make a vegan or dairy-free version, substitute heavy cream with coconut cream and use dairy-free dark chocolate, though the texture might be slightly different.
