Ingredients
Key Ingredients for Chewy Hazelnut Chocolate Brownies
To create these chewy hazelnut chocolate brownies, you need some key ingredients:
- 1 cup (225g) unsalted butter
- 1 ½ cups (300g) granulated sugar
- 4 large eggs
- 1 teaspoon pure vanilla extract
- 1 cup (125g) all-purpose flour
- ¾ cup (65g) unsweetened cocoa powder
- ½ teaspoon sea salt
- 1 cup (150g) chopped hazelnuts
- 1 cup (175g) semi-sweet chocolate chips
These ingredients work together to bring rich flavor and a perfect chewy texture.
Measurement Details
When measuring, accuracy is key. Use a kitchen scale for the best results. A scale ensures that you have the right amounts of flour and cocoa powder. For butter, you can simply use a measuring cup. If you don’t have a scale, level off dry ingredients with a knife. This will help you avoid too much flour or cocoa, which can ruin the texture.
Potential Ingredient Substitutions
If you need to swap ingredients, here are some ideas:
- Replace unsalted butter with coconut oil for a dairy-free treat.
- Use brown sugar instead of granulated sugar for a deeper flavor.
- Swap hazelnuts for walnuts or pecans to change the nutty flavor.
- For a gluten-free option, use almond flour instead of all-purpose flour.
These substitutions can help you adapt the recipe to fit your needs while keeping the brownies delicious.

Step-by-Step Instructions
Prepping the Oven and Baking Pan
First, you need to preheat your oven to 350°F (175°C). This step is key for even baking. While the oven heats, grab a 9x13 inch (23x33 cm) baking pan. Grease it well, then line it with parchment paper. Make sure some paper hangs over the edges. This will help you lift the brownies out later.
Creating the Butter and Sugar Mixture
Next, melt 1 cup (225g) of unsalted butter in a medium saucepan over low heat. Stir it as it melts for even heating. Once it's melted, remove the pan from the heat. Now, add 1 ½ cups (300g) of granulated sugar to the butter. Mix it until smooth and creamy. Let this mixture cool for a few minutes.
Combining Wet and Dry Ingredients
Once the butter and sugar mixture is slightly warm, it's time to add eggs. Whisk in 4 large eggs, one at a time. Then, add 1 teaspoon of pure vanilla extract. Mix until everything blends well. In another bowl, combine 1 cup (125g) of all-purpose flour, ¾ cup (65g) of unsweetened cocoa powder, and ½ teaspoon of sea salt. Whisk these dry ingredients together until there are no lumps. Gradually stir this dry mix into the wet mixture. Be careful not to over-mix. This will keep your brownies chewy and soft.
Folding in Hazelnuts and Chocolate Chips
Now, it's time for the fun part! Fold in 1 cup (150g) of chopped hazelnuts and 1 cup (175g) of semi-sweet chocolate chips. Make sure they spread evenly throughout the batter. This is where the magic happens, as the chocolate and nuts add rich flavors and textures.
Baking and Cooling the Brownies
Pour the brownie batter into your prepared baking pan. Use a spatula to smooth the top. Then, place the pan in the oven. Bake for 25-30 minutes. You’ll know they are done when the edges are set. A toothpick should come out with a few moist crumbs. After baking, take the brownies out and let them cool in the pan for 15 minutes. Carefully lift them out using the parchment paper and transfer them to a wire rack. Let them cool completely before cutting them into squares. Enjoy your chewy hazelnut chocolate brownies!
Tips & Tricks
Achieving the Perfect Chewy Texture
To get that perfect chewy texture in your brownies, you need to mix carefully. Over-mixing can lead to tough brownies. Combine wet and dry ingredients until just mixed. Use room-temperature eggs; they blend better. Additionally, using semi-sweet chocolate chips adds to the chewiness. They melt slightly, creating a gooey center.
Common Mistakes to Avoid
One common mistake is baking too long. Brownies should be soft in the center when done. Check them at 25 minutes. If a toothpick comes out with a few crumbs, they are ready. Another mistake is not lining the pan. Parchment paper helps you remove the brownies easily. Lastly, don’t skip the salt. It enhances the chocolate flavor.
Enhancing Flavor and Presentation
For a flavor boost, try adding a pinch of espresso powder. It deepens the chocolate taste without being too strong. You can also mix in sea salt flakes on top for contrast. For presentation, dust warm brownies with powdered sugar. Add whole hazelnuts on top for a nice touch. Serve them with a scoop of vanilla ice cream for an extra treat.
Pro Tips
- Tip Title: Use High-Quality Chocolate: Choose semi-sweet chocolate chips with a high cocoa content for richer flavor and better melting consistency.
- Tip Title: Don't Overmix the Batter: Mix until just combined to ensure your brownies remain chewy and prevent them from becoming cakey.
- Tip Title: Cool Before Cutting: Allow the brownies to cool completely before cutting them into squares for cleaner edges and easier serving.
- Tip Title: Experiment with Nuts: Feel free to substitute hazelnuts with walnuts or pecans for a different texture and flavor profile in your brownies.
Variations
Nut-Free Version of Chewy Brownies
You can still enjoy chewy brownies without nuts. Simply leave out the hazelnuts. Replace them with extra chocolate chips. This keeps the brownies rich and tasty. You can also add crushed cookies for crunch. This way, you keep the texture while avoiding nuts.
Gluten-Free Option
To make gluten-free brownies, swap regular flour for gluten-free flour. Use a 1:1 gluten-free blend that works well in baking. The texture will still be chewy and delicious. Just check your chocolate chips for any gluten. This option ensures everyone can enjoy these treats.
Flavor Twist Ideas (Mint, Espresso, etc.)
Add extra flavor to your brownies for a fun twist. For a mint flavor, mix in peppermint extract. Start with half a teaspoon and adjust to taste. If you love coffee, add a tablespoon of espresso powder. This will give the brownies a rich depth. You can also try adding orange zest for a fresh touch. Each variation brings a new taste to your chewy brownies!
Storage Info
Best Ways to Store Brownies
To keep your chewy hazelnut chocolate brownies fresh, store them in an airtight container. This helps prevent them from drying out. Place parchment paper between layers to avoid sticking. If you want to keep them extra soft, add a slice of bread to the container. The bread keeps the brownies moist.
How Long Do Brownies Last?
When stored properly, these brownies last about 3 to 5 days at room temperature. If you refrigerate them, they can last up to a week. However, the fridge may change their texture, making them less chewy. If you want them to last longer, freezing is a great option.
Freezing Instructions
To freeze your brownies, first, let them cool completely. Cut the brownies into squares, then wrap each piece tightly in plastic wrap. Place the wrapped brownies in a freezer-safe bag or container. They can stay frozen for up to three months. When you're ready to enjoy them, thaw them in the fridge overnight or at room temperature for a few hours. This way, you always have a sweet treat on hand!
FAQs
How to tell when brownies are done?
To check if your brownies are done, look for set edges. The center should be soft but not wet. Insert a toothpick into the center. It should come out with a few moist crumbs. If it comes out clean, the brownies may be overcooked. Remember, brownies continue to cook as they cool.
Can I use other types of nuts in this recipe?
Yes, you can swap hazelnuts for other nuts! Walnuts, pecans, or almonds work well. Each nut adds a different flavor and crunch. Just chop them to a similar size as hazelnuts. This way, they mix evenly in the batter.
What is the best way to cut brownies?
To cut brownies neatly, let them cool completely. Use a sharp knife for clean cuts. Dip the knife in hot water, then dry it off. This helps make each slice smooth. Wipe the knife between cuts for the best results.
How can I make brownies more fudgy?
To make fudgier brownies, reduce the flour slightly. You can also add an extra egg yolk. This adds richness and moisture. Another tip is to bake them for less time. Check for doneness a few minutes early for that perfect fudgy texture.
