Ingredients for Nutella Brownies

- 1 cup (226 g) unsalted butter, melted & cooled for at least 10 minutes
- 1 ¼ cups (250 g) brown sugar, packed
- 1 ¼ cups (355 g) Nutella chocolate hazelnut spread
- 2 large eggs + 1 egg yolk, room temperature
- 1 ½ teaspoons vanilla extract
- 2 ½ cups (285 g) all-purpose flour
- 2 teaspoons cornstarch (cornflour in the UK)
- ½ teaspoon baking powder
- ½ teaspoon salt
- ¼ cup (70 g) additional Nutella chocolate hazelnut spread (optional, for topping)
Step-by-Step Instructions
- Preheat your oven to 350°F (177°C). Line a 9×9-inch baking pan with parchment paper.
- In a large bowl, combine the melted, cooled butter and brown sugar. Stir well until fully combined.
- Add the Nutella to the butter-sugar mixture and stir until smooth and well incorporated.
- Add the eggs and egg yolk one at a time, stirring thoroughly after each addition. Then, mix in the vanilla extract.
- In a separate medium-sized bowl, whisk together the flour, cornstarch, baking powder, and salt.
- Gradually add the dry ingredients to the Nutella mixture, stirring until completely combined.
- Spread the batter evenly into the prepared baking pan.
- Drop dollops of the additional Nutella over the batter. Use a butter knife to swirl it into the surface for a marbled effect.
- Bake for 40-45 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (avoid overbaking to keep them fudgy).
- Allow the brownies to cool completely in the pan before cutting and serving. Enjoy!
Perfect Pairings: Serving Suggestions
These Nutella Brownies are delicious on their own, but you can elevate them with a scoop of vanilla ice cream or a dollop of whipped cream. For a decadent twist, drizzle with melted chocolate or caramel sauce. Pair with a glass of cold milk or a cup of coffee for the ultimate treat!
Keep It Fresh: Storage and Reheating Tips
Store your brownies in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. To reheat, pop them in the microwave for 10-15 seconds for a warm, gooey texture. For longer storage, wrap individual slices in plastic wrap and freeze for up to 3 months.
Mix It Up: Recipe Variations
Add a crunchy texture by folding in ½ cup of chopped hazelnuts or walnuts into the batter. For a chocolatey twist, mix in ½ cup of chocolate chips. If you’re feeling adventurous, swirl in peanut butter or caramel sauce along with the Nutella topping for a unique flavor combination.
Quick Tips for Success
Ensure your butter is *cooled* before mixing to avoid cooking the eggs. Use a *light-colored metal pan* for even baking and to prevent over-browning. Don’t overmix the batter—just combine until the ingredients are incorporated. And remember, it’s better to slightly underbake than overbake for fudgy brownies!
Common Questions Answered
Can I use salted butter?
Yes, but omit the added salt in the recipe
Can I skip the cornstarch?
It helps create a tender texture, but you can substitute with an equal amount of flour if needed.
Why room temperature eggs?
They blend more smoothly into the batter, ensuring a consistent texture. Happy baking!
