Decadent Fudgy Flourless Hazelnut Brownies with Irresistible Hot Chocolate Fudge Sauce
Prepare yourself for an extraordinary dessert experience with these **Fudgy Flourless Hazelnut Brownies**. They are so incredibly fudgy, intensely dense, and melt-in-your-mouth rich, truly like savoring pure fudge in brownie form – but with a healthier twist. When elevated by a luscious **Hot Chocolate Fudge Sauce**, these brownies transform into an utterly addictive treat you won’t be able to resist.
What makes them even more remarkable is their composition: low in carbs, completely flourless, and naturally gluten-free. It’s genuinely challenging to believe they offer a healthier alternative while you’re indulging in their deep, chocolatey goodness. They taste every bit as sinful and decadent as they look. Oh, the sheer delight of sweet chocolate and the nutty crunch of hazelnuts! These brownies are simply amazing. There’s really nothing more to say, except to experience them for yourself.

The Magic of Flourless Brownies: A Healthier Indulgence
You might be wondering, “healthier than regular brownies, how so?” It comes down to the ingenious use of hazelnut meal instead of traditional flour. This simple substitution not only makes these brownies naturally gluten-free and lower in carbohydrates but also infuses them with a rich, distinctive nutty flavor that perfectly complements the deep chocolate. The result is a brownie that delivers all the indulgence without the heavier, sometimes guilt-inducing, aspects of its flour-based counterparts.
Beyond Traditional: Nutty and Naturally Sweet
Think of them as a sophisticated cousin to Nutella brownies, yet arguably even better. Why better? Because there’s no actual Nutella involved. Instead, we harness the core components that make Nutella so beloved – hazelnuts, chocolate, and a touch of sweetness – and combine them in their purest form. This allows the genuine flavors of high-quality chocolate and roasted hazelnuts to shine through, creating a truly authentic and profound taste experience. You get that familiar, comforting hazelnut-chocolate profile, but with a depth and richness that feels far more gourmet.

Indeed, when you consider that hazelnuts, chocolate, and oil form the foundation of Nutella, these brownies leverage those very elements. But by making them from scratch, you control the quality of ingredients, the sweetness level, and avoid any unwanted additives. This results in a purer, more intensely flavored brownie that truly celebrates the synergy between these two classic ingredients.
The Core Ingredients: Hazelnuts and Rich Chocolate
The secret to their unparalleled depth lies in the quality of your chocolate and the presence of hazelnut meal. Hazelnuts, with their distinctively sweet and earthy flavor, provide the perfect counterpoint to the bitterness and richness of dark chocolate. When ground into a fine meal, they contribute to the brownie’s unique texture—dense, moist, and utterly satisfying, without the need for any traditional flour.


Crafting Your Perfect Fudgy Brownies
The baking process for these brownies is surprisingly straightforward, yielding results that taste far more complex than the effort required. When they first emerge from the oven, these brownies are wonderfully fragile and delicate, with a glistening, almost liquid center. It’s crucial to resist the urge to cut into them immediately. Allowing them to cool completely is the key to achieving that perfect fudgy texture. Once cooled, your knife will slice through them with remarkable ease, like soft butter, revealing a dense, moist, and deeply satisfying interior.
Tips for Ultimate Fudginess
- **Quality Chocolate is Key:** Opt for a high-quality semi-sweet chocolate with a good cocoa percentage (like 80% cocoa solids) for the best flavor and texture.
- **Don’t Overbake:** This is paramount for fudgy brownies. The center should still be quite gooey when you pull them out of the oven. They will continue to set as they cool.
- **Patience is a Virtue:** Cooling completely allows the brownies to firm up and develop their signature dense, fudgy consistency. Cutting them warm will likely result in a delicious, but crumbly, mess.
- **Room Temperature Eggs:** Ensure your eggs are at room temperature for better emulsification with the melted chocolate and butter mixture, leading to a smoother batter.

The Irresistible Bonus: Hot Chocolate Fudge Sauce
As if the brownies weren’t enough, they come with an incredible bonus: a rich, velvety hot chocolate fudge sauce. That luscious drizzle truly takes these brownies from fantastic to unforgettable. This isn’t just any sauce; it’s a warm, decadent blanket of chocolatey goodness that perfectly complements the nutty richness of the brownies.
An Unforgettable Dessert Experience
I distinctly remember a recent evening, “being forced” (with a smile, of course) to sit through the entire collection of *Scream* movies by my daughter. There I was, balancing a pan of warm brownies on my lap, adorned with a generous scoop (okay, maybe five scoops) of vanilla bean ice cream, and absolutely drowned in this glorious hot chocolate fudge sauce. Every single “torturous” second of that movie marathon was undeniably worth it for the sheer bliss of that dessert. The combination of warm, dense brownie, cold melting ice cream, and the rich, flowing sauce creates a symphony of textures and temperatures that is truly heavenly. It’s moments like these that make baking, and especially indulging, so incredibly special.

Storage and Enhanced Flavor
One of the most remarkable qualities of these flourless hazelnut brownies is how they evolve over time. If it’s even possible, they become even fudgier the day after baking, and remarkably, continue to improve in texture and depth of flavor for a few days. The flavors meld, and the density settles into an almost truffle-like consistency. Store them in an airtight container at room temperature for up to 3-4 days, or in the refrigerator for longer. A quick zap in the microwave can revive their warm, gooey center, especially when serving with that divine hot chocolate fudge sauce.
Why These Brownies Will Become Your New Favorite
From their rich, chocolatey base to the earthy crunch of hazelnuts, and the optional yet highly recommended hot fudge sauce, these brownies offer a truly gourmet experience. They cater to a variety of dietary needs, being gluten-free and lower in carbs, without compromising on taste or texture. Whether you’re a seasoned baker or just starting out, this recipe is straightforward and yields consistently spectacular results. Prepare to impress your family and friends, or simply treat yourself to a moment of pure, unadulterated bliss. These brownies are more than just a dessert; they’re an experience.

Fudgy Flourless Hazelnut Brownies with a Hot Chocolate Fudge Sauce
Ingredients
For the Brownies:
- 8 oz semi-sweet chocolate of choice – (I used 80% cocoa solids for a richer flavor)
- 8 oz unsalted butter
- 1 tablespoon pure vanilla extract
- 1 cup granulated sweetener (or fine white granulated sugar)
- 3 large eggs (beaten)
- 5 oz hazelnut meal
For the Hot Chocolate Sauce:
- 3 oz bittersweet chocolate (minimum 70%-80% cocoa solids)
- ½ cup thickened/heavy cream
- 1 teaspoon instant espresso powder
- 1 tablespoon granulated sweetener (substitute with coconut sugar or golden syrup for a different flavor profile)
Instructions
For the Brownies:
-
Preheat your oven to 176°C (350ºF). In a microwave-safe bowl, combine the chocolate and butter. Melt in 30-second increments, stirring well after each interval, until the mixture is completely melted and beautifully glossy. Alternatively, you can gently melt these ingredients in a heavy-based saucepan over low heat, stirring constantly to prevent burning.
-
Once melted, stir in the vanilla extract and your chosen granulated sweetener (or sugar). Set aside and allow the mixture to cool slightly. This step is important to prevent the eggs from cooking when added.
-
In a separate bowl, whisk the eggs until well beaten. Gradually whisk the beaten eggs into the cooled chocolate mixture (either in the bowl or the saucepan). Then, fold in the hazelnut meal until just combined. Pour the rich batter evenly into a 9-inch baking tin that has been lined with baking or parchment paper, ensuring it extends over the sides for easy removal later.
-
Bake in the preheated oven for 35-40 minutes. The brownies are done when the top has set and appears slightly crinkled, but the center still feels wonderfully gooey when gently pressed. Remember, a slightly underbaked brownie is a fudgy brownie! Remove from the oven and allow to cool completely in the tin before attempting to cut them. They are very delicate when warm, and cooling ensures clean, perfect slices. Cut into 16 squares.
For the Hot Chocolate Sauce:
-
Break the bittersweet chocolate into pieces and place them in a microwave-safe bowl. Add the thickened/heavy cream and instant espresso powder. Microwave in 30-second intervals, stirring thoroughly between each, until the chocolate is completely melted and the sauce is smooth and glossy. (Alternatively, combine all ingredients in a heavy-based saucepan and melt them together over very low heat, stirring constantly.)
-
Stir the sauce well to ensure all ingredients are fully incorporated. Pour it into a jug or a small serving bowl, ready to drizzle generously over your warm or cooled brownies. Enjoy!
