Ingredients
Essential Ingredients for Fudgy Brownies
To create the ultimate chocolate hazelnut brownies, you’ll need a handful of essential ingredients that contribute to their rich taste and fudgy texture. Here’s what you’ll need:
- 1 cup of unsalted butter
- 2 cups of granulated sugar
- 4 large eggs
- 1 cup of all-purpose flour
- 3/4 cup of cocoa powder
- 1/2 teaspoon of salt
- 1 teaspoon of vanilla extract
- 1 cup of chopped hazelnuts
- 1 cup of semi-sweet chocolate chips
Optional Add-ins for Extra Flavor

- A swirl of hazelnut spread in the batter
- Additional nuts like walnuts or pecans for more texture
Step-by-Step Instructions
Preparing Your Baking Tools
Before you start mixing your ingredients, it’s important to prepare your baking tools. Preheat your oven to 350°F and line a 9×13 inch baking pan with parchment paper, ensuring that the edges overhang slightly for easy removal later. Grease the paper with a bit of butter to prevent sticking.
Mixing the Batter
Begin by melting the butter in a saucepan over low heat. Once melted, remove from heat and stir in the sugar until well combined. Let the mixture cool slightly before adding the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
In a separate bowl, sift together the flour, cocoa powder, and salt. Gradually fold these dry ingredients into the wet mixture until just combined. Be careful not to overmix to maintain the desired fudgy texture. Finally, fold in the chopped hazelnuts and chocolate chips.
Baking to Perfection
Pour the batter into your prepared pan, spreading it evenly with a spatula. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Allow the brownies to cool in the pan for at least 15 minutes before lifting them out using the parchment paper overhang.

Pro Tips
Achieving the perfect chocolate hazelnut brownies is all about balance. Here are some pro tips to ensure your brownies turn out just right:
- Use high-quality cocoa powder and chocolate for the best flavor.
- Be sure to let the melted butter and sugar mixture cool slightly before adding the eggs to prevent them from cooking.
- Do not overbake; a slightly underdone center will continue to set as the brownies cool, ensuring a gooey texture.
- For a more pronounced hazelnut flavor, consider toasting the hazelnuts before adding them to the batter.
Remember, the key to perfect brownies is to check them a few minutes before the end of the baking time. This way, you can adjust based on your preference for fudgy versus cakey brownies. Explore our Salted Caramel Fudge Brownies for another delightful twist!

FAQ
Can I use a different type of nut instead of hazelnuts?
Yes, you can substitute hazelnuts with other nuts such as walnuts, pecans, or almonds. Each type will bring a slightly different flavor and texture to the brownies, but they will all complement the chocolate well. Simply ensure that the nuts are chopped into small, even pieces before incorporating them into the batter.
How can I make these brownies gluten-free?
To make these brownies gluten-free, you can replace the all-purpose flour with a gluten-free flour blend. Ensure that the blend you use is suitable for baking and includes a binding agent like xanthan gum to help the brownies hold together. The rest of the ingredients are naturally gluten-free, so this substitution will allow those with gluten sensitivities to enjoy the brownies without any issues.
What is the best way to store these brownies?
The best way to store chocolate hazelnut brownies is in an airtight container at room temperature. They will stay fresh for up to 3 days this way. If you need to store them for a longer period, place them in the refrigerator for up to a week. For an even longer storage solution, you can freeze the brownies for up to 3 months. Just ensure they are well wrapped to prevent freezer burn, and thaw them at room temperature before serving.
