A quick and easy one-bowl Nutella brownie recipe with a crunchy toasted hazelnut topping, delivering a rich, fudgy texture and delightful nutty crunch.

Ingredients

Scale
  • 1 cup (320g) Nutella
  • 3/4 cup (95g) all-purpose flour
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 4 tbsp (57g) unsalted butter, melted
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • For the Hazelnut Crunch Topping:
  • 1/2 cup (70g) hazelnuts, toasted and roughly chopped
  • 2 tbsp (25g) brown sugar
  • 1 tbsp (14g) butter, melted
  • 1/4 tsp cinnamon (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper or lightly grease it.
  2. Toast the hazelnuts on a baking sheet at 350°F (175°C) for about 10 minutes until golden and fragrant. Let cool and roughly chop.
  3. In a small bowl, combine toasted hazelnuts, brown sugar, melted butter, and optional cinnamon. Stir well and set aside.
  4. In a large mixing bowl, whisk together Nutella, granulated sugar, and melted butter until smooth.
  5. Add eggs and vanilla extract to the bowl and mix until the batter is glossy and slightly thickened.
  6. Sift or sprinkle flour and salt over the batter and gently fold in with a spatula until just combined. Avoid overmixing.
  7. Pour the batter into the prepared pan and smooth the top evenly.
  8. Sprinkle the hazelnut crunch topping evenly over the batter, pressing lightly to help it stick.
  9. Bake for 20-25 minutes, checking at 20 minutes with a toothpick; moist crumbs are ideal.
  10. Remove from oven and cool completely in the pan on a wire rack for at least 30 minutes.
  11. Lift brownies out using parchment overhang, cut into 9 squares, and serve.

Notes

Warm Nutella slightly if too thick for easier mixing. Avoid overmixing flour to keep brownies fudgy. Toast hazelnuts properly for best crunch and flavor. Cool brownies completely before slicing to prevent crumbling.
