As the batter swirled together, the glossy chocolate‑hazelnut mixture seemed to whisper promises of crackly tops, fudgy centers, and that melt‑in‑your‑mouth feeling that makes kids and adults alike squeal with delight.
What makes this Nutella brownie stand out isn’t just the brand name—although the iconic hazelnut spread does bring an instant depth of flavor that ordinary cocoa can’t match. It’s the careful balance of butter, sugar, and a touch of flour that gives you that perfect chew without turning the brownies into a cake. Imagine cutting into a square and seeing a glossy, slightly cracked surface that gives way to a soft, almost molten interior that clings to the fork. The secret?

🥗 Ingredients Breakdown
The Foundation
1 cup Nutella – This is the heart of the recipe, providing both chocolate and hazelnut flavor in one smooth package. The natural oil content in Nutella helps keep the brownies moist, and its sweetness reduces the need for additional sugar. If you ever wonder why store‑bought brownies never taste as rich, it’s because they often lack this dual‑flavor component.
½ cup unsalted butter – Melted butter adds richness and contributes to that coveted fudgy crumb. Using unsalted butter lets you control the salt level precisely, which is crucial for balancing the sweet notes. Look for butter with a bright yellow hue; it usually indicates a higher butterfat content.
Aromatics & Spices
¾ cup granulated sugar – Sugar not only sweetens but also helps create a tender texture by interfering with gluten formation. The right amount ensures the brownies are sweet without being cloying, and it also aids in caramelizing the top during baking.
2 large eggs – Eggs at room temperature incorporate more easily into the batter, creating a smooth, glossy mixture that traps air for a light interior. They also act as a binding agent, ensuring the brownies hold together when cut.
½ teaspoon vanilla extract – A splash of vanilla amplifies the chocolatey aroma and rounds out the hazelnut notes, making the overall flavor profile more cohesive.
The Secret Weapons
¼ cup unsweetened cocoa powder – Adding pure cocoa deepens the chocolate intensity without adding extra sugar. It also contributes to the dark, almost mahogany color that signals a truly chocolatey treat.
¼ teaspoon salt – A pinch of salt is the unsung hero that sharpens every flavor, preventing the brownies from tasting flat. It also balances the sweetness of the Nutella and sugar, making each bite more satisfying.
Optional: ¼ cup chopped hazelnuts or chocolate chips – Adding nuts gives a pleasant crunch, while chocolate chips create pockets of gooeyness that melt into the batter. Both options elevate the texture and add visual interest.
Finishing Touches
Extra Nutella for topping (about ¼ cup) – Swirling a dollop of Nutella on top before baking creates a marbled effect that looks as beautiful as it tastes. This final flourish adds an extra layer of richness and a glossy finish that makes the brownies look bakery‑ready.
When selecting your Nutella, choose a jar that feels heavy for its size—this usually indicates a higher proportion of hazelnuts and cocoa. For butter, aim for European‑style butter if you can find it; its higher butterfat content makes the brownies richer. If you’re allergic to nuts, you can substitute the hazelnut‑laden Nutella with a chocolate‑only spread, but be prepared for a slightly different flavor profile. With your ingredients prepped and ready, let's get cooking. Here’s where the fun really begins...
🍳 Step-by-Step Instructions
Preheat your oven to 350°F (175°C) and line a 9×13‑inch baking pan with parchment paper, letting the paper overhang on the sides for easy removal later. While the oven warms, take a moment to appreciate the aroma of butter melting in a saucepan—a scent that signals good things are on the way. Once the butter is fully melted, remove it from the heat and let it cool just a touch so it doesn’t scramble the eggs later.
In a large mixing bowl, combine the melted butter with the entire cup of Nutella, stirring until the mixture is smooth, glossy, and a uniform hazelnut‑chocolate swirl. This step is crucial: the longer you whisk, the more air you incorporate, which helps create that slightly airy crumb you love. As you stir, you’ll notice the batter becoming thick yet pourable—perfect for the next stage.
Add the granulated sugar, vanilla extract, and a pinch of salt to the Nutella‑butter blend, mixing until everything is fully integrated. The sugar will dissolve partially, giving the batter a slightly grainy texture that will smooth out once the eggs are added. At this point, the kitchen should be filling with a sweet, nutty perfume that makes your stomach rumble.
Crack the two eggs into a small bowl, whisk them just until the yolk and white combine, then pour them into the main batter. Stir gently but continuously for about 30 seconds, watching the batter transform from thick to silky and glossy. You’ll notice small bubbles forming around the edges—those are signs of a well‑emulsified mixture.
Sift together the flour and unsweetened cocoa powder over the batter, then fold them in using a spatula. The folding motion should be gentle—over‑mixing will develop gluten, leading to a cakey texture you definitely don’t want. As the dry ingredients disappear, the batter will regain its glossy sheen, and you’ll see the faint swirl of cocoa creating a marbled appearance.
If you’re using optional chopped hazelnuts or chocolate chips, now is the moment to fold them in. Distribute them evenly so each bite gets a surprise crunch or a burst of melted chocolate. For an extra visual impact, reserve a tablespoon of chocolate chips to sprinkle on top before the final swirl.
Pour the batter into the prepared pan, using the spatula to smooth the top. Drizzle the warmed extra Nutella over the surface and, with a butter knife, gently swirl it through the batter, creating a marbled pattern that will bake into a glossy, eye‑catching top. The visual contrast between the deep brown cocoa and the lighter Nutella ribbons is what makes these brownies Instagram‑ready.
Slide the pan into the preheated oven and bake for 25‑30 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs attached. The top should be slightly cracked and fragrant, giving off a sweet, nutty aroma that fills the kitchen. Resist the urge to overbake; the brownies will continue to set as they cool, ensuring a fudgy interior.
And there you have it! But before you dig in, let me share some tips that will take this from great to absolutely unforgettable...
🔐 Expert Tips for Perfect Results
The Taste Test Trick
Before you bake, give the batter a quick taste. It should be sweet, slightly salty, and intensely chocolatey with a hint of hazelnut. If it feels too thick, a splash of milk will loosen it without compromising the fudgy texture. Trust your palate; a small adjustment now can save you from a bland batch later.
Why Resting Time Matters More Than You Think
Once out of the oven, let the brownies rest in the pan for at least 15 minutes. This allows the internal steam to redistribute, giving you clean, neat squares when you cut. Skipping this step often leads to crumbly pieces that fall apart, especially if you’re serving them to guests who expect a tidy presentation.
The Seasoning Secret Pros Won’t Tell You
A pinch of flaky sea salt sprinkled on top just before serving can transform the flavor profile, creating a delightful contrast between sweet and salty. Professional bakers use this technique to highlight the chocolate’s depth, and it works wonders with Nutella’s natural hazelnut notes.
The Moisture Balance Hack
If you live in a dry climate, add a tablespoon of sour cream or Greek yogurt to the batter. The extra moisture prevents the brownies from drying out during baking, and the slight tang balances the sweetness, making each bite more complex. I discovered this trick during a winter bake‑off when my kitchen was unusually dry.
The Perfect Pan Choice
A dark, non‑stick metal pan conducts heat more efficiently, giving you a crispier edge. However, if you prefer a softer crust, a glass baking dish works beautifully, though you may need to add a couple of extra minutes to the bake time. Experiment with both to discover which texture you love most.
Storage Savvy
Store the cooled brownies in an airtight container with a slice of bread on top; the bread will absorb excess air and keep the brownies moist for up to a week. For longer storage, wrap individual squares in foil and freeze—they’ll stay fresh for three months and can be reheated in a microwave for a quick treat.
🌈 Delicious Variations to Try
One of my favorite things about this recipe is how versatile it is. Here are some twists I've tried and loved:
Salted Caramel Swirl
Replace the extra Nutella topping with a caramel sauce and sprinkle flaky sea salt before baking. The caramel adds a buttery sweetness while the salt accentuates the hazelnut flavor, creating a sweet‑salty symphony.
Espresso Infusion
Dissolve a tablespoon of instant espresso powder in the melted butter before mixing with Nutella. The coffee notes deepen the chocolate flavor, making the brownies taste almost like a mocha dessert.
White Chocolate Hazelnut Crunch
Stir in ¼ cup of white chocolate chips and a handful of toasted hazelnuts. The white chocolate adds a creamy contrast, while the toasted nuts give a satisfying crunch that complements the soft interior.
Berry Burst
Fold in a cup of fresh raspberries or frozen blueberries just before baking. The berries release a subtle tartness that cuts through the richness, and they create beautiful speckles of color throughout the brownies.
Minty Fresh
Add a teaspoon of peppermint extract to the batter and top with crushed peppermint candies after baking. This variation is perfect for holiday gatherings, offering a refreshing twist on the classic chocolate‑hazelnut combo.
Gluten‑Free Adaptation
Swap the all‑purpose flour for a 1:1 gluten‑free blend, and you’ll still achieve that fudgy texture. Just be sure the blend contains xanthan gum or a similar binder to maintain structure.
📦 Storage & Reheating Tips
Refrigerator Storage
Place the cooled brownies in an airtight container, layering a sheet of parchment between layers if you’re stacking them. They will stay fresh for up to five days, and the chill helps keep the crumb firm, making slicing easier.
Freezing Instructions
Wrap each brownie individually in plastic wrap, then place them in a freezer‑safe zip‑top bag. They can be frozen for up to three months. When you’re ready to enjoy, let them thaw at room temperature for 20 minutes, or pop them directly into the microwave for a quick warm‑up.
Reheating Methods
For a microwavable treat, place a brownie on a microwave‑safe plate, cover with a damp paper towel, and heat for 15‑20 seconds. If you prefer oven reheating, preheat to 300°F (150°C) and warm for 5‑7 minutes; this restores the crust’s slight crispness while keeping the center gooey.
