Transform your dessert game with these incredibly fudgy, rich Nutella brownies that combine the perfect chocolate base with stunning hazelnut swirls. This recipe delivers bakery-quality brownies right from your home kitchen, featuring a perfectly crackly top and an irresistibly moist center.
Why This Recipe Works
The secret to these exceptional brownies lies in the careful balance of ingredients and technique. By melting the chocolate slowly and incorporating air into the eggs and sugar, we prepare that coveted crackly top while maintaining a fudgy interior. The Nutella swirl not only adds visual appeal but brings a rich hazelnut flavor that elevates these brownies beyond the ordinary.

Essential Equipment
- 9×13 inch baking pan
- Parchment paper
- Double boiler or heat-safe bowl
- Rubber spatula
- Wire whisk
- Electric mixer (stand or hand-held)
- Offset spatula
- Sharp knife for swirling
Step-by-Step Instructions
Preparation Phase (30 minutes)
- Position your oven rack in the middle and preheat to 350°F (175°C)
- Line your baking pan with parchment paper, leaving overhang for easy removal
- Grease the parchment paper lightly with butter
- Organize all ingredients on your counter, measured and ready
Creating the Perfect Brownie Base (20 minutes)
- Chocolate Melting Technique
- Fill bottom of double boiler with 2 inches of water
- Heat water until just simmering
- Add chocolate and butter to top bowl
- Stir occasionally until completely melted and glossy
- Remove from heat and let cool for 10 minutes
- Egg Mixture Preparation
- In a large bowl, combine eggs, sugar, and vanilla
- Beat on medium-high speed for 7-8 minutes
- Mixture should be pale yellow and form ribbons when lifted
- Combining Wet Ingredients
- Pour cooled chocolate mixture into egg mixture
- Fold gently with a rubber spatula
- Maintain air bubbles for crackly top
- Dry Ingredient Integration
- Sift together flour, cocoa powder, and salt
- Add to wet ingredients in three portions
- Fold until just combined
- If using hazelnuts, fold in now
Nutella Swirl Creation (10 minutes)
- Prepare Nutella Mixture
- Warm chocolate hazelnut spread and cream in the microwave (30 seconds).
- Stir until smooth and slightly runny (but not too thin). If the Nutella becomes overly warm and too liquidy, let it cool slightly before proceeding.
- Add salt and mix well.
- Assembly Process
- Pour 3/4 of brownie batter into the prepared pan.
- Dollop Nutella mixture across the surface, ensuring even spacing.
- Add the remaining brownie batter between Nutella dollops.
- Use a knife to create swirl patterns:
- Draw long lines lengthwise, then perpendicular lines to create a marble effect.
- Avoid over-swirling to maintain distinct patterns and prevent the batter from blending completely.
- Keep the knife or skewer near the surface; avoid pressing too deeply into the batter. This ensures the swirl remains prominent on the top layer.
Baking Process (32-35 minutes)
- Initial Bake
- Bake for 20 minutes
- Rotate pan 180 degrees
- Continue baking 12-15 minutes
- Testing Doneness
- Insert toothpick 2 inches from edge
- Should have moist crumbs
- Center should be set but slightly jiggly
Cooling and Cutting (2 hours)
- Cooling Process
- Cool in pan for 1 hour
- Lift out using parchment overhang
- Cool completely on wire rack
- Cutting Technique
- Use large sharp knife
- Heat knife under hot water
- Wipe dry between cuts
- Cut into 16 equal squares
