Irresistible Espresso Hazelnut Cookies with Dark Chocolate Drizzle: Your New Favorite Indulgence
These buttery and crisp hazelnut cookies are infused with the rich depth of instant espresso, elegantly piped into a delicate cat tongue shape, and finished with a luxurious dark chocolate drizzle. Prepare for a cookie experience that’s anything but ordinary.
The Quest for the Perfect Cookie: A Culinary Revelation
A few weeks ago, while sifting through my extensive recipe archives, a startling realization hit me: my collection was severely lacking in cookie recipes. It felt like I could count the number of cookie recipes I’d meticulously crafted and shared on a single hand. For someone who dedicates so much time to baking, this was a glaring oversight that simply had to be rectified.
Now, don’t get me wrong, I truly adore cookies. Yet, when considering the vast spectrum of desserts that I regularly crave, cookies often find themselves closer to the bottom of my personal list. My heart usually gravitates towards the comforting warmth of muffins and the satisfying simplicity of quick breads. Other casual treats like elegant tea cakes or straightforward one-layer cakes also rank highly in my affection. This preference means that when I *do* decide to share a cookie recipe with you, it has to be exceptionally special, a little out of the ordinary, and truly worth your baking time.
Introducing Your New Favorite: Espresso Hazelnut Cookies
These espresso hazelnut cookies fit that description perfectly, and then some. They aren’t just unique; they’re an experience. For me, any dessert that incorporates espresso—or anything within the glorious realm of coffee—is an instant triumph. In fact, my lifelong love affair with coffee began quite early: I famously asked my parents for an espresso machine when I was a mere three years old. Totally normal, right? (Said absolutely no one, ever.) This deep-seated passion ensures that when I bake with espresso, I do so with an informed and enthusiastic palate, striving for true coffee perfection.
The Secret Ingredient: Instant Espresso Powder
The exquisite flavor of this cookie dough batter comes from my absolute favorite instant espresso coffee powder. It’s arguably one of the most frequently used ingredients in my pantry, a true baking MVP. While it tastes rather awful if you try to drink it straight (trust me on this), its power in baking is undeniable. I often use it as a dry powder, or sometimes, I’ll dilute a tiny amount with hot water to create a concentrated espresso “extract.” This method is unparalleled for infusing glazes or batters with a rich, deep espresso note without adding excessive liquid or bitterness. It simply enhances and complements other flavors, especially chocolate and nuts, making them sing.
The Nutty Heart: Harnessing the Heavenly Hazelnut
These espresso hazelnut cookies boast a delightful crispness and a rich, buttery texture, reminiscent of classic shortbread or delicate sablés. The depth of flavor is truly remarkable, thanks to the harmonious blend of butter and, of course, whole toasted hazelnuts. The hazelnuts are finely ground into a coarse meal, similar to almond meal for those familiar with it in baking, and then meticulously folded into the cookie batter. This process ensures every bite is permeated with their distinctive, slightly sweet, and earthy aroma.
I am confidently positive that no other nut can truly rival the complex and utterly captivating flavor of the hazelnut. For me, nothing quite compares to its unique profile, which is why it takes center stage in this recipe.
A Note on Hazelnut Preparation: Making Life Easier
However, I must admit that hazelnuts can sometimes be the most high-maintenance of all nuts – a truly strange sentence to write, but true! Most readily available and affordable hazelnuts (I often find excellent ones at Trader Joe’s!) come with their skins still intact. These skins carry a noticeably bitter flavor, and for the vast majority of recipes, including this one, you’ll want to remove as much of them as possible to ensure the purest, sweetest hazelnut taste shines through.
To significantly simplify your baking process, I highly recommend seeking out blanched hazelnuts or even pre-made hazelnut meal. Both options are increasingly available in well-stocked grocery stores or online, though they might come with a slightly higher price tag. The convenience and superior flavor without the bitter skins are well worth the small investment.
Effortless Elegance: Piping for Perfection & No-Chill Convenience
The intricate shape and elegant lines of these cookies are achieved with the simple use of a piping bag fitted with a large star tip. While it might sound like a step reserved for advanced bakers, it actually makes the process incredibly quick and pain-free. Piping allows for uniform cookies that bake evenly and look stunning, resembling delicate “cat tongue” cookies, or *langues de chat*.
Unlike many cookie recipes that yield dozens upon dozens of cookies (which isn’t always a bad thing, depending on your audience!), this particular recipe has been thoughtfully scaled down to produce a more manageable batch of 14 to 15 cookies. This perfect quantity typically fits on a single standard baking sheet, minimizing baking time and cleanup. This smaller yield is also fantastic for those of us who, let’s just say, have very little self-control when faced with a mountain of delicious homemade cookies!
As an added and truly appreciated bonus, this recipe requires absolutely no chilling time. That’s right! The batter transitions seamlessly from mixing bowl to oven in a matter of minutes. The actual preparation of the batter itself takes less than 10 minutes, provided your hazelnuts are already toasted and ready to go. It’s a remarkably straightforward and simple recipe, perfect for satisfying sudden cookie cravings or for a quick impressive treat.
The Grand Finale: A Luscious Dark Chocolate Drizzle
Once baked to golden perfection and cooled, these exquisite cookies receive their final touch: a simple yet utterly rustic dark chocolate drizzle. The bittersweet notes of the chocolate are a magnificent complement to the robust espresso and the earthy sweetness of the hazelnuts, creating a flavor profile that is truly harmonious. Each bite is reminiscent of a perfectly crafted hazelnut mocha drink, but in a delightful, crisp cookie form. The visual appeal of the uneven, hand-drizzled chocolate adds to their charm, making them look as homemade and inviting as they taste. Enjoy these unique cookies as an afternoon treat, a delightful dessert, or a thoughtful gift for any coffee and nut enthusiast.

Ingredients
Espresso Hazelnut Cookie Dough:
- ½ cup (60 g) roasted blanched hazelnuts
- ½ cup + 2 tablespoons (75 g) unbleached all-purpose flour divided
- 1½ teaspoons instant espresso powder I recommend Medaglia d’Oro brand
- ¼ teaspoons kosher salt
- 6 tablespoons (3 oz; 85 g) unsalted butter softened
- ¼ cup (50 g) granulated sugar
- ½ (25 g) large egg room temperature, see notes for tips
- ½ teaspoon pure vanilla extract
Dark Chocolate Drizzle:
- 2 ounces (60 g) bittersweet chocolate coarsely chopped
- ½ tablespoon (8 g) unsalted butter
Instructions
-
Preheat the oven to 350°F (176°C) with a rack in the center position. Line a half sheet pan with parchment paper or a silicone baking mat. Set aside.
-
Prepare the Hazelnut Flour Mixture: Combine the blanched hazelnuts and two tablespoons (15 grams) of all-purpose flour in the bowl of a large food processor. Pulse the hazelnuts and flour together repeatedly until it forms an even, coarse meal (do not over pulse, or the nuts will clump and oil will begin to release and create nut butter). Set aside.
-
Combine the remaining all-purpose flour, espresso powder, and salt in a small bowl, and whisk together.
-
Place the butter in the bowl of a stand mixer fitted with a paddle attachment. Beat the butter at medium speed for 1 minute, or until creamy. Add the granulated sugar, and beat at medium speed for an additional 2 to 3 minutes, or until the mixture is light and fluffy. Add the egg and vanilla, and beat at low speed for an additional minute or so, scraping down the bowl to ensure all of the ingredients are evenly incorporated.
-
On low speed, add the all purpose flour mixture and mix until just combined. Fold in the hazelnut meal with a spatula. Place the cookie batter in a pastry bag fitted with a large star tip. Pipe two-inch strips of dough onto the prepared baking sheets, leaving about 1½ inches between them. They should fit on one standard sheet pan.
-
Bake for 12 to 14 minutes, rotating the sheet halfway, or until the edges begin to caramelize and lightly brown. Carefully transfer the cookies to a cooling rack and allow them to cool completely before decorating.
-
Prepare Chocolate Drizzle: Combine the chopped chocolate and butter in a small microwave-safe bowl. Microwave the chocolate in 20 to 25 second intervals, stirring with a rubber spatula after each interval, or until the mixture has melted and is smooth. Place the cooled cookies on a wire rack set above a sheet of wax paper. Using a spoon or fork, drizzle the cookies with the warm, melted chocolate back and forth over the tops of the cookies. Don’t worry if it isn’t perfect! Refrigerate the cookies for 10 to 15 minutes, or until the chocolate has set completely. Cookies can be stored in an airtight container at room temperature for up to 5 days.
Tips for Success:
- To halve an egg easily, whisk one full egg in a small bowl (it should be roughly 50 grams in weight). Use a kitchen scale or tablespoon to measure.
- You can also substitute the whole hazelnuts in this recipe with 60 grams of Bob’s Red Mill hazelnut meal.
