Introduction
If you’re on the hunt for a dessert that marries elegance with simplicity, look no further than hazelnut meringue bombs. These delightful confections combine the airy texture of meringue with the rich crunch of hazelnuts, creating a treat that's as visually appealing as it is delicious.
Perfect for special occasions or a sweet yet light ending to your meal, hazelnut meringue bombs invite creativity. You can fill them with luscious creams or mousses and decorate them to suit any festive atmosphere, making them a versatile addition to your dessert repertoire.
Ingredients
- 1 cup granulated sugar
Granulated sugar is essential for achieving the glossy texture and stability in meringue. As it dissolves, it creates a sweet flavor while also helping to create those iconic peaks you expect in meringue. - 3 large egg whites
Egg whites are the primary ingredient required for meringue. They provide the structure and volume necessary, transforming into fluffy whipped peaks when beaten properly. - 1 cup lightly roasted hazelnuts, roughly chopped
These nuts bring a delightful crunch and rich, nutty flavor to your meringue bombs. Roasting enhances their essence, adding depth to each bite. - 1/4 cup additional chopped hazelnuts (optional, for topping)
Sprinkling more hazelnuts on top not only adds extra texture but also makes for a more visually appealing presentation. It's an optional step that elevates the dish. - 2 tbsp granulated sugar (for the mousseline)
This sugar helps sweeten the mousseline cream that fills our meringue bombs, ensuring a perfectly balanced flavor against the light meringue. - 1 1/2 tbsp all-purpose flour
Flour is used to stabilize the custard in the mousseline and give it a thicker consistency. It helps create a rich and velvety cream that complements the airy meringue. - 3/4 cup whole milk
Milk adds creaminess to the mousseline. Heating it before incorporating it into the custard ensures smooth blending and a luscious texture. - 6-8 tbsp unsalted butter, at room temperature
Butter enriches the mousseline, providing a velvety mouthfeel. Whipping it until fluffy ensures that it incorporates air, creating a light texture. - 1 tsp vanilla extract
Vanilla extract enhances the overall flavor of the mousseline cream, adding a warm and aromatic note that pairs beautifully with hazelnuts.
Directions & Preparation
Step 1: Preheat your oven to 225°F (107°C) and line a baking sheet with parchment paper.
Preheating your oven is crucial in ensuring that your meringues cook evenly and don’t become chewy. The low temperature helps dry them out gently, leading to a perfect crunchy exterior.
Step 2: In a clean, grease-free bowl, separate the egg whites from the yolks.
Ensuring your bowl and utensils are completely clean and free from any grease is essential for proper meringue. Even a little bit of fat can prevent the egg whites from whipping into a stable foam.
Step 3: Using a mixer, beat the egg whites on high speed until frothy, then gradually add 1 cup of granulated sugar.
Gradually introducing sugar while whipping helps the egg whites absorb the sweetness without collapsing. This process creates a meringue with a stable structure, achieving shiny peaks.
Step 4: Continue whipping until stiff peaks form and the mixture is glossy, about 15 minutes.
Stiff peaks indicate that air has been adequately incorporated into the meringue. At this point, the mixture should hold its shape well, perfect for piping or spooning.
Step 5: Fold in the chopped hazelnuts gently using a spatula, making sure not to deflate the meringue.
Folding is a delicate process that preserves the air you've created. Incorporating the hazelnuts adds texture without losing the lightness of the meringue.
Step 6: Pipe or spoon meringue onto the prepared baking sheet, spacing them about an inch apart.
A piping bag allows for uniform shapes, but if you lack one, spoons work just as well. Ensure even spacing to allow air circulation during baking.
Step 7: Sprinkle additional hazelnuts on top if desired, then bake for about 2 hours.
Baking slowly at a low temperature allows meringues to dry out fully without browning. Keep an eye on them; they should be dry to the touch when done.
Step 8: Turn off the oven and let the meringues cool inside for an hour.
Cooling in the oven prevents moisture from re-entering the meringues. This step is vital for achieving a crispy texture that contrasts beautifully with the creamy filling.
Step 9: For the mousseline, whisk together the egg yolks, sugar, and vanilla extract in a medium saucepan.
Starting with cold ingredients and whisking them helps create a smooth custard base. Ensure there are no lumps before adding other ingredients.
Step 10: Add 1.5 tbsp flour and mix until smooth, then incrementally whisk in the heated milk.
Warm milk prevents curdling when combined with egg yolks; adding it slowly helps temper the yolks for a smooth custard.
Step 11: Cook the mixture over medium heat, whisking constantly until thickened, about 2 minutes.
Continuous whisking ensures that the custard doesn’t scorch. It should be thick enough to coat the back of a spoon, indicating it's ready to cool.
Step 12: Remove from heat and let it cool to room temperature, then whip the butter until light and fluffy.
Whipping the butter adds air and volume, preparing it to blend seamlessly with the cooled custard, resulting in the airy, creamy texture of the mousseline.
Step 13: Combine the custard and butter in thirds, mixing until fully incorporated and smooth.
Incorporating the custard gradually minimizes the risk of curdling. If the mixture stubbornly separates, gentle reheating can help to achieve a smooth consistency.
Step 14: Once the mousseline is ready, fill cooled meringue shells with the cream and serve immediately or chill briefly before serving.
Filling them just before serving ensures the meringues remain crunchy. If chilled, allow them to come back to room temperature before enjoying for the best texture.

Creating the Perfect Meringue
Meringue is not simply whipped egg whites; it's a science. The secret lies in achieving the right texture through well-beaten egg whites and gradually added sugar. A clean bowl, proper mixing speed, and patience are crucial for success. Once you master the meringue maestro approaches, variations and flavors awaiting your creative touch are endless.
The Art of Incorporating Hazelnuts
While hazelnuts add delightful flavor and texture, incorporating them into the meringue requires finesse. A gentle folding motion is key to preserving the air you've whipped into the egg whites. Aim for a cohesive blend without losing volume, and remember that well-chopped hazelnuts ensure they distribute evenly.
Tips for a Successful Mousseline Cream
Creating a smooth mousseline cream can feel daunting, but understanding temperature control is vital. Gradually introduce warm milk to egg yolks, and be ready to whisk continuously. The incorporation of butter should be done carefully — if separating occurs, gentle heat will help rescue the emulsification. Overall, your patience during each stage leads to a silky, luscious filling.
FAQs
What can I do if my meringue mixture is too runny?
If your meringue appears too runny, it could be due to insufficient whipping. Return to mixing and increase the speed until stiff peaks form.
How do I know if my meringues are undercooked?
If meringues are chewy or sticky on the outside when cool, they require more time in the oven to dry out completely.
Can I reduce the sugar in the meringue?
Reducing sugar in meringue can affect its stability and texture, so it’s not recommended as sugar is crucial for proper structure.
What if my mousseline cream is too thick?
If your mousseline is too thick, you can soften it by whisking in a tiny bit of room-temperature milk until you reach the desired consistency.
Why is my hazelnut flavor not strong enough?
Make sure to use quality, roasted hazelnuts. Consider increasing the amount in the mix if you desire a more pronounced flavor.
What should I do if my meringues crack during baking?
Cracking can often result from sudden changes in temperature. To reduce this, avoid opening the oven door while baking.
