Fudgy Nutella Brownies

Fudgy Nutella Brownies are rich, deeply chocolatey, and filled with a smooth layer of Nutella in the center. They combine a dense brownie batter made with cocoa powder and dark chocolate with a creamy hazelnut spread filling, creating an indulgent dessert with soft centers, set edges, and a beautiful crackly top.
These brownies use both melted butter and neutral oil. The butter provides richness and flavor, while the oil helps the brownies stay moist and fudgy. Granulated sugar and brown sugar add sweetness, but they also contribute to the texture. Whisking the warm butter, oil, and sugars thoroughly helps begin dissolving the sugar, while whisking the eggs into the mixture creates the glossy base needed for that delicate brownie crust.
The Nutella is layered through the middle instead of simply being stirred into the batter. Half of the brownie batter is spread in the pan, followed by a smooth layer of Nutella and the remaining batter. This creates a distinct Nutella center in every slice without taking away from the rich chocolate flavor of the brownies themselves.
Dark chocolate is folded into the batter and scattered over the top, adding melted pockets of chocolate throughout the brownies. A small amount of instant espresso powder strengthens the cocoa flavor without making the brownies taste strongly like coffee.
One of the most important parts of this recipe happens after baking. The center will still look soft when the brownies first come out of the oven, but it should not look liquid. Allowing the brownies to cool for at least 30 to 45 minutes gives the chocolate, Nutella, butter, and eggs time to settle into the proper fudgy texture. Cutting them too soon can make the center appear raw even when the brownies have been baked correctly.
These Fudgy Nutella Brownies are ideal when you want something richer than a classic brownie but still simple enough to make without frosting or elaborate decorating. Every slice has a shiny top, a soft chocolate center, melted pieces of dark chocolate, and a creamy layer of Nutella.
Why You’ll Love These Fudgy Nutella Brownies

These brownies are designed for anyone who prefers a dense and fudgy brownie rather than a light, cakey one. The combination of melted butter, neutral oil, two whole eggs, and an additional egg yolk gives the brownies a rich texture that remains soft after cooling.
The Nutella layer makes the recipe especially indulgent. Instead of getting lost in the chocolate batter, the Nutella stays concentrated in the middle, giving each brownie a distinct chocolate-hazelnut center.
They also have a beautiful crackly top. The warm butter mixture is whisked with both sugars, and the eggs are then whisked in until the mixture becomes pale and slightly thick. Taking the full amount of time to whisk these ingredients helps create the thin, glossy crust associated with bakery-style brownies.
Dark chocolate adds even more flavor and texture. Some of the chocolate is folded into the batter, while the rest is scattered over the surface before baking. This produces chocolate pockets inside the brownies and an appealing finish on top.
Although these brownies taste especially rich, the batter is straightforward to prepare. The butter is melted in a pan, the wet ingredients are whisked together, and the dry ingredients are sifted directly into the mixture. No electric mixer is necessary.
The recipe is also easy to personalize because the amount of dark chocolate and Nutella can be adjusted according to preference. You can use enough Nutella to create a noticeable middle layer and add as much dark chocolate as you enjoy without changing the basic method.
What Are Fudgy Nutella Brownies?
Fudgy Nutella Brownies are cocoa brownies layered with Nutella and filled with dark chocolate. They have a dense, moist center, lightly puffed edges, and a thin crackled crust on top.
Unlike cakey brownies, which usually have a lighter crumb and more noticeable rise, these brownies contain a higher proportion of fat and relatively little flour. The recipe uses only ¾ cup of all-purpose flour alongside melted butter, oil, eggs, an additional egg yolk, cocoa powder, and chocolate. This balance helps produce a compact, rich texture.
Nutella is a smooth cocoa and hazelnut spread. In this recipe, it is placed between two layers of brownie batter. As the brownies bake, the Nutella becomes warm and soft while remaining concentrated in the center.
The brownies are finished with dark chocolate, which provides more intense chocolate flavor and melted pockets throughout each serving. The unsweetened cocoa powder forms the foundation of the brownie flavor, while the espresso powder makes that flavor taste deeper.
The finished brownies should have set, puffed edges and a center that looks soft but not liquid. They will continue to set while cooling, which is why the resting period is an essential part of the recipe.
Ingredients You’ll Need
Granulated Sugar
Granulated sugar sweetens the brownies and plays an important role in creating the crackly top. Whisking it thoroughly with the very warm melted butter and oil helps the sugar begin to dissolve.
For the best result, whisk the sugar mixture continuously for the full minute specified in the instructions. It should begin to look smooth and glossy before the eggs are added.
Brown Sugar
Packed brown sugar adds sweetness, moisture, and a subtle depth of flavor. Because it contains molasses, it helps support the brownies’ soft and fudgy consistency.
Pack the brown sugar into the measuring cup so the recipe receives the correct amount.
Unsalted Butter
Melted butter gives the brownies richness and a classic buttery flavor. It should be very warm when combined with the sugars but not so hot that it begins cooking the eggs when they are added.
After melting the butter over low heat, remove it from the heat and allow it to cool for one or two minutes. It should remain warm enough to help dissolve the sugar.
Neutral Oil
Oil helps keep the brownies moist and soft. Any neutral-flavored oil can be used because it will not compete with the chocolate and Nutella flavors.
Using butter and oil together provides the flavor of butter while retaining the soft texture that oil contributes.
Eggs and Egg Yolk
The recipe uses two large eggs and one additional egg yolk. The whole eggs bind the batter and provide structure, while the extra yolk contributes fat and richness without adding another egg white.
Whisking the eggs into the sugar mixture for a full minute is especially important. The mixture should become paler and slightly thicker, helping produce the brownies’ shiny, delicate crust.
Vanilla Extract
Vanilla extract rounds out the flavor of the cocoa, dark chocolate, and Nutella. It does not make the brownies taste like vanilla; instead, it adds warmth and balance to the chocolate.
All-Purpose Flour
All-purpose flour gives the brownies enough structure to hold together after cooling. Because this is a fudgy brownie recipe, only a modest amount is needed.
Sift the flour with the other dry ingredients to eliminate lumps. After adding it to the wet mixture, fold the batter only until no dry streaks remain. Too much mixing can make the finished brownies less tender.
Unsweetened Cocoa Powder
Unsweetened cocoa powder gives the batter its deep chocolate flavor. Because no additional sugar is included in the cocoa, the sweetness can be controlled by the granulated sugar, brown sugar, Nutella, and dark chocolate already in the recipe.
Sifting the cocoa powder is helpful because it tends to form small lumps that can be difficult to incorporate through gentle folding.
Instant Espresso Powder
Instant espresso powder intensifies the chocolate flavor. The recipe uses only ½ teaspoon, so it supports the cocoa and dark chocolate rather than overwhelming them.
It can make the finished brownies taste deeper and richer without turning them into coffee-flavored brownies.
Salt
Salt balances the sweetness from the sugars and Nutella. It also helps bring out the flavor of the cocoa powder and dark chocolate.
Although ½ teaspoon may seem like a small amount, it keeps the overall flavor from tasting flat or excessively sweet.
Dark Chocolate
Dark chocolate creates rich, melted chocolate pockets inside the brownies. Approximately half is folded into the batter, and the remaining chocolate is scattered over the surface.
The recipe allows you to measure the chocolate according to your preference. It may be used in chips or pieces, provided it is in a form that can be folded evenly through the batter.
Nutella
Nutella forms the creamy chocolate-hazelnut layer in the center of the brownies. Because the recipe does not require an exact quantity, use enough to form an even layer over the first half of the batter.
The layer should be spread gently so it remains distinct before being covered with the remaining brownie batter.
The Secret to a Fudgy Brownie Texture
Several parts of this recipe work together to produce a fudgy texture. The batter includes melted butter and neutral oil, both of which add fat and moisture. It also uses an extra egg yolk, which contributes richness without adding the firmer structure that another egg white would provide.
The relatively small amount of flour is equally important. Flour gives brownies structure, but too much can move the texture toward cakey rather than fudgy. Measuring the ¾ cup, or 95 grams, accurately helps maintain the intended balance.
The batter should also be folded gently after the dry ingredients are added. Vigorous or prolonged mixing can develop more gluten, resulting in a firmer or less tender brownie.
Finally, the brownies should not be baked until the center looks completely firm. The edges should be set and puffed, while the center should remain soft but no longer liquid. Residual heat will continue setting the brownies as they cool.
How to Create the Crackly Brownie Top
The thin, crackled crust begins with the warm butter and sugar mixture. After the butter has melted and cooled slightly, it is whisked with the oil, granulated sugar, and brown sugar for one full minute. The warmth helps begin dissolving the sugar, and thorough whisking creates a glossy mixture.
The two eggs, additional egg yolk, and vanilla are then added. Whisking for another full minute incorporates the eggs thoroughly and makes the mixture look pale and slightly thick.
Do not shorten these whisking stages. They are not only for combining the ingredients; they help build the glossy base that produces the crackly surface as the brownies bake.
Once the dry ingredients are added, switch from vigorous whisking to gentle folding. This preserves the texture you created while preventing the flour from being overmixed.
How to Add the Nutella Layer
Begin by pouring approximately half of the prepared brownie batter into the pan and smoothing it into an even layer.
Add the Nutella over the batter and spread it carefully. The exact quantity can be adjusted based on how thick you want the filling, but it should form a consistent layer so the Nutella is distributed throughout the finished brownies.
Cover the Nutella with the remaining brownie batter. Smooth the surface gently, taking care not to mix the top batter into the filling too much.
Sprinkle the reserved dark chocolate over the surface before baking. When the brownies are sliced after cooling, the Nutella should appear as a soft, rich layer between the two portions of chocolate brownie.
Tips for the Best Fudgy Nutella Brownies
Use melted butter that is very warm but not hot. Warm butter helps with the glossy sugar mixture, but extremely hot butter could affect the eggs when they are added.
Whisk for the full amount of time. Whisk the butter, oil, and sugars for one minute, then whisk the eggs, egg yolk, and vanilla for another full minute. These stages help create the crackled top.
Sift the dry ingredients. Cocoa powder can contain stubborn lumps, so sifting creates a smoother and more evenly mixed batter.
Fold gently once the flour is added. Stop as soon as the dry ingredients are incorporated. Overmixing can make the brownies firmer and less tender.
Divide the dark chocolate. Fold about half into the batter and reserve the rest for sprinkling over the top.
Spread the Nutella evenly. An even middle layer ensures that the chocolate-hazelnut filling appears throughout the batch rather than being concentrated in only a few slices.
Watch the center rather than relying only on time. Ovens can bake differently, so look for set, puffed edges and a soft center that is no longer liquid.
Do not cut the brownies immediately. Let them cool for at least 30 to 45 minutes so the center can set into a fudgy consistency.
How to Tell When the Brownies Are Done
These brownies bake at 350°F for approximately 25 to 30 minutes. Because they are intended to be fudgy, the center should still appear soft when they come out of the oven.
Look closely at the edges. They should appear set and slightly puffed, showing that the brownie batter has baked around the outside.
The center should not look wet or liquid, but it does not need to look completely firm. If you continue baking until the entire center appears fully set in the oven, the brownies may become firmer as they cool.
The Nutella filling also keeps the middle especially soft. This can make freshly baked brownies appear less set than a batch without a filling. The cooling period allows the melted fats and chocolate to settle.
For the intended consistency, remove the brownies once the edges are set and the center is soft but not liquid, then leave them undisturbed for at least 30 to 45 minutes.
Why the Brownies Need to Cool Before Slicing
Cooling is not simply an optional waiting period in this recipe. It is the final stage that allows the brownies to develop their proper structure.
When they first come out of the oven, the butter, oil, Nutella, and dark chocolate are all very warm. The center may look extremely soft and can appear raw if sliced immediately, even when the brownies have been baked correctly.
As the brownies rest, the chocolate and fats begin to settle, and the center becomes stable enough to slice. This is what transforms the warm, loose interior into a dense and fudgy brownie.
Allow at least 30 to 45 minutes of cooling time. If you want especially neat slices, leave the brownies until they have cooled more fully before cutting them.
Use a sharp knife when slicing. Wiping the blade between cuts can help keep the layers and edges cleaner, particularly because the Nutella center will remain soft.
Storage Instructions
Store the cooled Fudgy Nutella Brownies in an airtight container at room temperature. Keeping them covered prevents the exposed edges from drying out and helps preserve their soft texture.
Allow the brownies to cool completely before closing them inside a container. Storing them while they are still warm may trap condensation and make the surface damp.
If stacking the brownies, place parchment paper between the layers to prevent the soft Nutella centers and chocolate pieces from sticking together.
The brownies can also be kept in the refrigerator if you prefer a firmer, denser texture. Allow a chilled brownie to sit briefly at room temperature before serving if you would like the Nutella center and chocolate pieces to soften again.
Freezing Instructions
These brownies can be frozen after they have baked and cooled completely.
For convenient individual servings, slice the cooled brownies first. Separate the pieces with parchment paper and place them in a freezer-safe container or wrap them securely before freezing.
Thaw the brownies before serving. Leaving them at room temperature allows the brownie and Nutella layers to soften gradually.
Make sure the brownies are protected from air in the freezer. Proper wrapping helps prevent the exposed edges from drying out and protects the chocolate flavor.
Make-Ahead Instructions
Fudgy Nutella Brownies are well suited to making ahead because they need time to cool and set before slicing.
Bake the brownies as directed, let them cool completely, and keep them covered until you are ready to serve. Preparing them in advance also makes it easier to produce neat slices because the Nutella filling and brownie center will have enough time to settle.
If you prefer a very soft texture, serve the brownies at room temperature. If they have been refrigerated, allow them to sit out until the chocolate and Nutella soften to your liking.
Variations and Substitutions
Any neutral-flavored oil can be used in the batter. Choose one that will not introduce a strong flavor that competes with the cocoa and Nutella.
The quantity of dark chocolate can be adjusted according to preference. Add a moderate amount for occasional melted chocolate pockets or use a more generous amount for a richer result.
You can also adjust the amount of Nutella based on how prominent you want the filling to be. Use enough to create a visible, even layer while still leaving room for brownie batter above and below it.
Dark chocolate chips or dark chocolate pieces can both work. If using a chocolate bar, chop it into pieces small enough to distribute through the batter.
Avoid adding extra liquid ingredients because the batter has been balanced to bake into a fudgy but stable brownie. Additional liquid could make the center take longer to set.
Serving Ideas
These Fudgy Nutella Brownies are rich enough to serve on their own. The Nutella filling and dark chocolate pieces give them plenty of flavor without the need for frosting.
Serve them at room temperature for a soft, fudgy center and creamy Nutella layer. For a firmer and denser bite, serve them slightly chilled.
They also pair well with a glass of cold milk, a cup of coffee, or espresso. The slight bitterness of coffee balances the sweetness and reinforces the brownies’ chocolate flavor.
For dessert, serve a brownie while it is slightly warm so the dark chocolate and Nutella become softer. Because the brownies are very rich, they also work well when cut into smaller pieces for dessert trays, gatherings, or sharing.
Frequently Asked Questions
Can I leave out the instant espresso powder?
The espresso powder is included to deepen the chocolate flavor. The recipe uses only a small amount, so the brownies should not taste strongly like coffee.
What kind of oil should I use?
Any neutral oil works. Use an oil without a strong flavor so the cocoa, dark chocolate, and Nutella remain the dominant flavors.
Why do I need an extra egg yolk?
The additional egg yolk adds fat and richness without including another egg white. This supports a softer, fudgier brownie center.
Why is the butter supposed to be warm?
Very warm butter helps the sugars begin to dissolve when whisked, which contributes to the glossy batter and crackly brownie top. It should not be extremely hot when the eggs are added.
Why didn’t my brownies develop a crackly top?
The butter and sugars may not have been whisked long enough, or the egg mixture may not have reached the pale and slightly thick stage. Whisk each mixture for the full minute before adding the dry ingredients.
Can I use chocolate chips instead of chopped chocolate?
Yes. The dark chocolate can be used in chips or small pieces. Fold approximately half into the batter and reserve the remainder for the top.
How much Nutella should I use?
The recipe does not require an exact amount. Use enough to spread an even layer over the first half of the batter. The quantity can be adjusted depending on how thick you want the Nutella center.
Why do the brownies look raw when I slice them?
They may have been sliced before they had enough time to set. The center remains very soft immediately after baking because of the butter, oil, chocolate, and Nutella. Let the brownies cool for at least 30 to 45 minutes before cutting.
How do I know when the center is baked?
The edges should be set and puffed, and the center should look soft but not liquid. The brownies will continue setting as they cool.
Can I bake the brownies longer for a firmer texture?
A slightly longer bake will produce a more firmly set brownie, but baking too long can reduce the intended fudgy texture. Use the appearance of the edges and center to decide when they are ready.
Why should I avoid overmixing?
Once the flour is added, excessive mixing can develop more gluten and give the brownies a firmer texture. Fold gently and stop as soon as the dry ingredients disappear into the batter.
Final Thoughts
Fudgy Nutella Brownies bring together a rich cocoa brownie, a soft chocolate-hazelnut center, and plenty of dark chocolate. The combination of melted butter, neutral oil, two eggs, and an additional egg yolk produces a dense texture, while the limited amount of flour keeps the center from becoming cakey.
The method is simple, but the small details make an important difference. Whisking the warm butter mixture with the sugars helps create a glossy base. Whisking the eggs for another full minute supports the crackly top, while gently folding the flour prevents the batter from being overworked.
Layering the Nutella between two portions of batter ensures that it remains noticeable in each slice. Dark chocolate folded inside and sprinkled over the top adds even more richness and creates soft chocolate pockets throughout the brownies.
Most importantly, let the brownies rest after baking. Although the center will look very soft when it first leaves the oven, it will set as it cools. Waiting at least 30 to 45 minutes produces the dense, fudgy consistency these brownies are meant to have.
If you love brownies with soft centers, shiny tops, rich chocolate flavor, and a generous Nutella filling, this is a recipe worth keeping.
