Ingredients for Nutella Brownie Recipe

Chocolate Base

• 120g (1/2 cup) unsalted butter
• 200g (1 cup) Nutella
• 100g (1/2 cup) granulated sugar
• 80g (1/3 cup) brown sugar

Structure & Texture

• 2 large eggs (room temperature)
• 1 tsp vanilla extract
• 95g (3/4 cup) all-purpose flour
• 30g (1/4 cup) unsweetened cocoa powder
• 1/2 tsp salt

Add-ins (Optional but Recommended)

• 80g (1/2 cup) chopped hazelnuts
• 80g (1/2 cup) dark chocolate chips

Step-by-Step Instructions

Step 1: Melt Butter and Nutella (5 minutes)

You place the butter and Nutella in a heatproof bowl and melt them together gently over a double boiler or in short microwave bursts, stirring until smooth and glossy. This creates the rich base that defines the fudgy texture.

Chef’s Tip: Always melt slowly and stir frequently to avoid overheating, which can cause the chocolate fats to separate and give you a grainy batter instead of a silky one.

Step 2: Whisk Sugars into the Mixture (3–4 minutes)

You add granulated sugar and brown sugar into the warm Nutella mixture and whisk until the texture thickens slightly and looks glossy. This step helps dissolve the sugar and contributes to that signature crackly top.

Chef’s Tip: Take your time whisking here because properly dissolved sugar improves both texture and appearance, giving you a smooth batter and that classic brownie crust.

Step 3: Add Eggs and Vanilla (4–5 minutes)

You crack in the eggs one at a time, whisking well after each addition, then stir in vanilla extract. The batter becomes thicker and shinier as you mix, which is exactly what you want for structure.

Chef’s Tip: Make sure your eggs are at room temperature so they incorporate easily, preventing the batter from splitting and ensuring even baking throughout.

Step 4: Fold in Dry Ingredients (3–4 minutes)

You sift in the flour, cocoa powder, and salt, then gently fold everything together using a spatula until just combined. Avoid overmixing so your brownies stay tender.

Chef’s Tip: Stop mixing as soon as you no longer see dry streaks, because overworking the batter develops gluten and leads to dense, cakey brownies instead of fudgy ones.

Step 5: Add Chocolate Chips and Hazelnuts (2 minutes)

You fold in the chocolate chips and chopped hazelnuts, distributing them evenly throughout the batter for extra texture and flavor.

Chef’s Tip: Toss the add-ins lightly in flour before mixing them in, which helps prevent them from sinking to the bottom during baking.

Step 6: Bake to Fudgy Perfection (25–30 minutes)

You pour the batter into a lined 8×8-inch pan, smooth the top, and bake at 175°C (350°F) until the edges are set but the center still looks slightly soft. This ensures a gooey middle once cooled.

Chef’s Tip: Check a few minutes early and look for moist crumbs on a toothpick rather than a clean result, because overbaking is the quickest way to lose that fudgy texture.

Nutritional Information (Per Serving)

Why You’ll Love This Recipe

• You get a deeply fudgy texture with a rich chocolate hazelnut flavor that feels bakery-quality, yet the process stays simple and beginner-friendly without requiring special equipment.
• The Nutella adds both sweetness and fat, which means you achieve consistent results every time without needing complicated chocolate tempering techniques.
• You can easily customize the recipe with add-ins or toppings, making it adaptable whether you want a simple treat or a more elevated dessert presentation.
• The brownies stay moist for days, which makes them perfect for meal prep, gifting, or preparing ahead for gatherings without losing quality.

Common Mistakes to Avoid

• Overbaking the brownies is one of the most common mistakes, and it happens because you wait for a clean toothpick; instead, you should remove them when the center still looks slightly underdone to preserve fudginess.
• Skipping the step of properly whisking sugar into the warm mixture can leave you with a grainy texture and prevent that glossy top from forming correctly.
• Using cold eggs can cause the batter to seize or mix unevenly, which affects both texture and consistency in the final bake.
• Overmixing after adding flour develops gluten, turning your brownies dense and cakey rather than soft and rich, so always mix gently and minimally.

Serving Suggestions

• You can serve these brownies slightly warm with a scoop of vanilla ice cream, allowing the heat to melt the ice cream into a rich, creamy sauce that complements the chocolate.
• Slice them into small squares and dust with cocoa powder or powdered sugar for a clean, elegant presentation that works well for gatherings.
• Turn them into a plated dessert by drizzling melted Nutella on top and adding crushed hazelnuts for a layered flavor and texture experience.
• Pair them with a strong coffee or espresso, which balances the sweetness and enhances the deep chocolate notes in each bite.

Healthier Alternatives and Ingredient Swaps

• You can reduce the sugar slightly because Nutella already contains sweetness, which helps lower overall sugar content without compromising flavor.
• Swap part of the butter with Greek yogurt to reduce fat while maintaining moisture, though the texture will be slightly lighter.
• Use whole wheat flour instead of all-purpose flour for added fiber, but keep the ratio balanced so the brownies remain tender.
• Replace chocolate chips with cacao nibs if you prefer a less sweet, more intense chocolate profile with added texture.

Storage and Meal Prep Tips

• Store the brownies in an airtight container at room temperature for up to three days, ensuring they stay soft and moist without drying out.
• Refrigerate them for up to one week if you prefer a firmer texture, but allow them to come to room temperature before serving for the best flavor.
• Freeze individual portions wrapped tightly in plastic wrap and stored in a container, which makes it easy to enjoy a quick dessert later without compromising quality.
• Reheat briefly in the microwave for 10–15 seconds to restore that soft, gooey center without overheating and drying them out.

Conclusion

This fudgy Nutella brownie recipe works because it balances rich ingredients with simple techniques, giving you reliable results every time. Once you master it, you can easily adapt flavors and textures to match your preferences.
