There’s something magical about the combination of chocolate and hazelnuts. When you transform these beloved flavors into a light, crispy, melt-in-your-mouth meringue cookie, pure bliss happens. I’ve spent years perfecting this recipe, and today I’m thrilled to share my ultimate chocolate hazelnut meringue cookies with you.
These delicate treats feature a crisp exterior that shatters gently between your teeth, giving way to a slightly chewy interior studded with rich chocolate and toasted hazelnuts. The contrast of textures and flavors creates a truly unforgettable dessert experience that’s surprisingly easy to achieve at home.
What Makes These Meringue Cookies Special?
Unlike traditional cookies that rely on flour, butter, and leavening agents, meringue cookies showcase the remarkable transformation of humble egg whites. When whipped with sugar and a touch of acid, they create a glossy, stable foam that bakes into ethereal, cloud-like cookies.
The addition of hazelnuts brings a wonderful earthiness that perfectly complements the deep chocolate notes. I’ve also incorporated a hint of espresso powder to intensify the chocolate flavor without making the cookies taste like coffee. The result is a sophisticated cookie that feels special enough for celebrations yet simple enough for everyday indulgence.
The Science Behind Perfect Meringues
Before diving into the recipe, let’s understand what makes meringues work. Meringue is essentially a foam of egg white proteins that have been denatured (unfolded) through physical agitation (whipping). When we add sugar, it stabilizes this foam by drawing out moisture and increasing viscosity. The acid (cream of tartar in this recipe) helps stabilize the egg whites further by preventing over-coagulation of proteins.
Temperature plays a crucial role in meringue cookies. We bake them low and slow to gradually dry out the structure rather than cooking it quickly. This creates that distinctive crisp exterior while maintaining a slightly chewy center.
Ingredients You’ll Need
For these chocolate hazelnut meringue cookies, I’ve carefully selected ingredients that work together to create the perfect texture and flavor profile:
| Ingredient | Amount | Function |
|---|---|---|
| Egg whites | 4 large (about 120g) | Provide structure and volume |
| Cream of tartar | ¼ teaspoon | Stabilizes the egg whites |
| Salt | Pinch | Enhances flavors |
| Granulated sugar | 1 cup (200g) | Sweetens and stabilizes meringue |
| High-quality cocoa powder | 3 tablespoons (18g) | Provides chocolate flavor |
| Espresso powder | ½ teaspoon | Enhances chocolate flavor |
| Dark chocolate | 4 oz (113g), finely chopped | Adds chocolate intensity and texture |
| Hazelnuts | 1 cup (150g), toasted and chopped | Provides nutty flavor and crunch |
| Vanilla extract | 1 teaspoon | Adds aromatic depth |
Essential Equipment
To achieve perfect meringue cookies, you’ll need:
- Stand mixer with whisk attachment (or hand mixer)
- Large, clean, dry mixing bowl (preferably metal or glass)
- Rubber spatula
- Baking sheets
- Parchment paper or silicone baking mats
- Piping bag with large round tip (optional, for more uniform cookies)
- Oven thermometer (highly recommended for accuracy)
- Kitchen scale (for precise measurements)
Step-by-Step Instructions
Let me walk you through creating these delightful cookies:
Preparing the Hazelnuts
- Preheat your oven to 350°F (175°C).
- Spread the hazelnuts in a single layer on a baking sheet.
- Toast for 8-10 minutes, or until fragrant and skins begin to crack.
- Transfer the hot nuts to a clean kitchen towel, fold the towel over, and rub vigorously to remove most of the skins.
- Allow to cool completely before chopping coarsely.
Making the Perfect Meringue
- Reduce oven temperature to 250°F (120°C) and line two baking sheets with parchment paper.
- Separate eggs carefully, ensuring no yolk contaminates the whites. (Pro tip: Separate eggs when cold, but let whites come to room temperature for 30 minutes before whipping for maximum volume.)
- In a perfectly clean, dry mixing bowl, add egg whites, cream of tartar, and salt.
- Begin whipping on medium-low speed until frothy.
- Gradually increase speed to medium-high and start adding sugar one tablespoon at a time, allowing each addition to incorporate before adding more.
- Continue whipping until stiff, glossy peaks form and sugar is completely dissolved (rub a small amount between fingers to check for graininess).
- Add vanilla extract and whip just until incorporated.
Incorporating the Chocolate and Hazelnuts
- Sift cocoa powder and espresso powder over the meringue.
- Using a large rubber spatula, fold gently with a downward stroke, then up and over, rotating the bowl slightly with each fold. Aim for minimal deflation.
- When cocoa is almost incorporated, add chopped chocolate and hazelnuts.
- Continue folding gently until everything is evenly distributed.
Forming and Baking the Cookies
- Using two large spoons or a piping bag fitted with a large round tip, portion the meringue onto prepared baking sheets, leaving about 1.5 inches between each cookie.
- For a more rustic look, use spoons to create swirled mounds about 2 inches in diameter.
- For more uniform cookies, pipe 2-inch rounds.
- Bake in the preheated oven for 60-70 minutes, or until the exteriors feel dry and firm.
- Turn off the oven and leave the door cracked open, allowing cookies to cool slowly in the oven for 1 hour.
- Remove from oven and cool completely on the baking sheets.
Troubleshooting Common Meringue Issues
Even experienced bakers occasionally encounter challenges with meringues. Here’s how to address common problems:
| Issue | Possible Cause | Solution |
|---|---|---|
| Weeping or beading | Sugar not fully dissolved | Whip longer to dissolve sugar completely |
| Flat, collapsed meringues | Oven temperature too high | Use an oven thermometer to verify temperature |
| Sticky centers | Insufficient baking time | Extend baking time; allow to dry in oven longer |
| Browned exterior | Oven temperature too high | Reduce temperature; position rack in middle of oven |
| Cracked meringues | Rapid temperature changes | Avoid opening oven during baking; cool slowly |
Variations to Try
While the classic chocolate hazelnut combination is divine, you can experiment with these variations:
- Chocolate Orange Meringues: Replace hazelnuts with candied orange peel and add 1 teaspoon orange zest.
- Mint Chocolate Meringues: Omit hazelnuts, add ¼ teaspoon mint extract, and use mint chocolate chips.
- Mocha Meringues: Double the espresso powder and add 2 tablespoons finely ground coffee beans.
- Coconut Chocolate Meringues: Replace hazelnuts with toasted coconut flakes.
Storing and Serving Suggestions
These meringue cookies are at their textural best within the first 24 hours after baking, but they can be stored in an airtight container at room temperature for up to 1 week. Avoid refrigeration, as humidity will soften the crisp exterior.
For an extra special dessert experience, try these serving ideas:
- Sandwich two cookies with a thin layer of chocolate ganache or hazelnut spread.
- Serve alongside a scoop of high-quality vanilla or coffee ice cream.
- Crumble over fresh berries and whipped cream for an elegant dessert.
- Package in decorative boxes or bags for homemade gifts.

Special Dietary Considerations
These meringue cookies are naturally gluten-free, making them perfect for those with gluten sensitivities or celiac disease. However, they do contain eggs and nuts, so they’re not suitable for those with these specific allergies.
For a dairy-free version, ensure your dark chocolate doesn’t contain milk solids (many high-quality dark chocolates are naturally dairy-free).
Why These Cookies Are Worth the Effort
I believe baking is an act of love, both for oneself and for others. While these meringue cookies require some patience and attention to detail, the results are so rewarding. There’s something deeply satisfying about transforming simple ingredients into something so elegant and delicious.
The contrasting textures—crisp exterior giving way to a slightly chewy center dotted with melty chocolate and crunchy hazelnuts—create a sensory experience that’s hard to match. Plus, the dramatic look of these cookies makes them perfect for special occasions when you want to impress without spending hours in the kitchen.
Expert Tips for Meringue Success
After years of baking meringues, I’ve gathered these essential tips:
- Weather matters: Humidity is the enemy of meringue. Choose a dry day for best results.
- Temperature is crucial: Room temperature egg whites whip to greater volume.
- Cleanliness is key: Any fat residue (including egg yolk) will prevent proper whipping.
- Add sugar gradually: This ensures proper dissolution and a stable meringue.
- Fold gently: Aggressive mixing will deflate your carefully whipped meringue.
- Use an oven thermometer: Most ovens run hot or cold, affecting baking results.
- Cool slowly: Rapid temperature changes cause cracking and collapse.
Frequently Asked Questions
Q: Can I make these cookies ahead of time for a party?
A: Yes! These cookies can be made 1-2 days in advance. Store them in an airtight container at room temperature. For the freshest texture, try to make them no more than 3 days before serving.
Q: Why did my meringue deflate when I added the cocoa powder?
A: Cocoa powder can be heavy and difficult to incorporate. Be sure to sift it first to remove lumps, then fold very gently using a rubber spatula. It’s normal to lose some volume, but gentle folding minimizes deflation.
Q: Can I use a hand mixer instead of a stand mixer?
A: Absolutely! A hand mixer works perfectly well for meringues, though it may take a few minutes longer to reach stiff peaks. Just be prepared for a bit of an arm workout!
Q: My cookies browned too much. What went wrong?
A: Oven temperature is likely the culprit. Many home ovens run hotter than their settings indicate. Use an oven thermometer to verify your temperature, and consider reducing the temperature by 25°F. Also, positioning your rack in the middle of the oven rather than near the top can help prevent browning.
Q: Can I substitute walnuts or almonds for the hazelnuts?
A: Absolutely! Any toasted nut works beautifully in this recipe. Almonds, walnuts, and pecans are particularly delicious alternatives. Just follow the same toasting process to enhance their flavor.
Q: How can I tell when the meringues are done baking?
A: The exterior should feel dry and firm to a gentle touch. If you pick one up carefully, it should feel light for its size. If you’re unsure, you can sacrifice one cookie by breaking it open—the inside should be dry or just slightly chewy, not wet.
Q: Why add cream of tartar?
A: Cream of tartar is an acid that stabilizes the egg white foam, helping it maintain volume and preventing it from weeping or collapsing. If you don’t have it, you can substitute the same amount of lemon juice or white vinegar.
Q: My meringue won’t form stiff peaks. What am I doing wrong?
A: Several factors could contribute:
- Egg whites may have yolk contamination
- Your bowl or beaters may have grease residue
- You may be using very fresh eggs (slightly older eggs actually whip better)
- You may have added the sugar too quickly Try starting over with room temperature egg whites and a spotlessly clean metal or glass bowl.
