Fudgy Hazelnut Nutella Brownies

Ingredients

Here’s what you’ll need to create this rich chocolate hazelnut cake:

  • 20.5cm/8inch square tin
  • 120g Unsalted Butter – Use room temperature butter for smooth mixing
  • 100g Dark Chocolate – For deep, intense flavor
  • 70g Milk Chocolate – Adds a creamy sweetness
  • 100g Nutella – Infuses the cake with a hazelnut-chocolate swirl
  • 20g Cocoa Powder – Enhances the chocolate depth
  • 1 tsp Ground Coffee – Elevates the chocolate flavor
  • 1 tsp Salt – Balances sweetness
  • 100g Caster Sugar – For a smooth texture
  • 70g Light Brown Sugar – Adds caramel notes
  • 2 Medium/Large Eggs – Room temperature for optimal emulsification
  • 70g All-Purpose Flour – Provides structure
  • 100g Hazelnuts – Toasted for extra flavor (optional)

Step-by-Step Instructions

Follow these steps to create your masterpiece:


  1. Preparation


    Preheat your oven to 170°C (340°F). Line a 20.5cm/8inch square tin with parchment paper for easy removal later.



  2. Melt the Chocolate Mixture


    In a microwave-safe bowl or over a double boiler, melt together the unsalted butter, dark chocolate, and milk chocolate. Stir regularly until smooth and homogenous.



  3. Incorporate Nutella


    Add the Nutella and let the residual heat slowly melt it into the chocolate mixture. Stir until fully combined.



  4. Mix Dry Ingredients


    Sift in the cocoa powder, ground coffee, and salt. Whisk until well combined.



  5. Whip the Egg Mixture


    In a separate bowl, combine the eggs, caster sugar, and light brown sugar. Using an electric mixer, whip the mixture until light, fluffy, and doubled in volume. This step is critical for a moist texture—take your time!



  6. Combine Mixtures


    Pour the whipped egg mixture into the chocolate-Nutella mixture and whisk until glossy and smooth.



  7. Add Flour and Hazelnuts


    Sift in the flour and fold gently until fully incorporated. Fold in the hazelnuts (toasted for extra crunch if desired).



  8. Bake and Chill


    Pour the batter into the prepared tin and spread evenly. Bake for ~25 minutes or until a toothpick inserted comes out clean. Let cool to room temperature, then refrigerate for at least 2 hours or overnight for optimal texture.



  9. Serve


    Slide the cake out of the tin, cut into 9 equal squares, and serve chilled for a rich, indulgent experience.


Frequently Asked Questions

1. Can I substitute hazelnuts with another nut?

Absolutely! Almonds, walnuts, or pecans work well in place of hazelnuts. Toast them lightly for enhanced flavor.

2. How long can I store the cake?

The cake can be stored in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze individual slices wrapped in plastic wrap.

3. What if I don’t have a square tin?

You can use a round tin of similar volume (about 20cm diameter). Adjust baking time slightly, checking for doneness after 20 minutes.

Conclusion

This Chocolate Hazelnut Cake is a testament to the magic of combining simple ingredients into something extraordinary. With its luscious texture, bold chocolate flavor, and nutty undertones, it’s sure to become a favorite in your dessert repertoire. Whether you’re serving it at a dinner party or enjoying it as a midnight treat, this cake is guaranteed to delight. Don’t forget to pair it with a cup of coffee or a scoop of vanilla ice cream for the ultimate indulgence. Happy baking!
