When I first made these Chocolate Hazelnut Brownies, I was floored by the depth of flavor and how easy they were to whip up. The combination of melted chocolate and crushed hazelnuts created a beautifully textured batter that didn’t require any special equipment—just a whisk and a bowl! I also discovered that allowing the brownies to cool completely before cutting helps them set up perfectly, preventing crumbs from falling everywhere.

One key to achieving that fudgy center is underbaking them slightly. I set my timer and always check them about five minutes early, and then let the residual heat do the rest. This way, they remain moist and rich, hitting that delicious sweet spot that keeps everyone coming back for more!

The Magic of Mixing

One of the great things about these Chocolate Hazelnut Brownies is how simple the mixing process is. By whisking the sugars and melted butter together first, you create a base that integrates the dry ingredients more easily. This method helps in achieving that ideal fudgy texture. When you add the melted chocolate, ensure it is not too hot; otherwise, it may cook the eggs upon contact. This can be avoided by allowing the chocolate to cool slightly before mixing it in.

Another great tip is to mix just until combined, particularly when you add the flour, cocoa powder, and hazelnuts. Overmixing can lead to dense brownies instead of the desired fudginess. Folding the mixture gently allows the leavening from the eggs to work effectively, creating a light yet rich brownie. Keep an eye out for a slight sheen; this indicates that you've mixed just enough to incorporate the ingredients without overdoing it.

Texture and Baking Perfection

To achieve a beautifully balanced texture, it’s important to monitor the baking time closely. Start checking your brownies at the 20-minute mark; they’re done when the edges begin to pull away from the pan and that classic toothpick test shows moist crumbs. Remember, the brownies will continue to set as they cool in the pan, so it's okay if you're unsure and they're slightly underbaked at that point. Overbaking can lead to dry brownies, which we definitely want to avoid!

The choice of an 8x8 inch pan is key for ensuring even baking. If you don't have one on hand, a 9x9 inch pan will work, but keep an eye on the time, as your brownies may bake slightly quicker. To ensure the brownies come out easily, use parchment paper for lining. This not only aids in easy removal but also helps prevent any sticking, allowing you to cut them into perfect squares.

Ingredients

Gather the following ingredients to make these delightful brownies:

Ingredients

1 cup (200g) granulated sugar
1/2 cup (100g) brown sugar
1/2 cup (115g) unsalted butter, melted
1 cup (200g) semisweet chocolate chips, melted
2 large eggs
1 tsp vanilla extract
1/2 cup (65g) all-purpose flour
1/2 cup (50g) hazelnuts, roughly chopped
1/4 cup (25g) cocoa powder
1/4 tsp salt

Once you have all the ingredients ready, you're set to start making these brownies!

Instructions

Follow these simple steps to bake your brownies:

Prepare the Oven

Preheat your oven to 350°F (175°C) and grease an 8x8 inch baking pan or line it with parchment paper.

Combine the Ingredients

In a large bowl, whisk together the granulated sugar, brown sugar, and melted butter until smooth. Add the melted chocolate, eggs, and vanilla, mixing until thoroughly combined.

Add Dry Ingredients

Sift in the flour, cocoa powder, and salt. Gently fold in the hazelnuts, being careful not to overmix.

Bake

Pour the brownie batter into the prepared pan, spreading it evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Cool and Serve

Let the brownies cool in the pan for at least 15 minutes before transferring to a wire rack. Once completely cooled, cut into squares and enjoy!

These brownies are best enjoyed fresh but can be stored in an airtight container for several days.

Pro Tips

For an extra touch, sprinkle some sea salt on top before baking for a delightful contrast to the sweetness.

Storage and Make-Ahead Tips

These brownies can be made ahead of time and stored for later enjoyment. Once they are fully cooled, you can keep them in an airtight container at room temperature for up to three days. For longer storage, these brownies freeze beautifully. Just wrap them tightly in plastic wrap and aluminum foil and they will last for up to three months in the freezer. To enjoy, simply thaw at room temperature or warm them slightly in the microwave for that fresh-out-of-the-oven taste.

If you've made a large batch or simply want to make some ahead of time, consider cutting the brownies into squares before freezing. This way, you can take out individual portions as needed, making them perfect for spontaneous treats or surprise guests.

Serving Suggestions

These Chocolate Hazelnut Brownies are delicious on their own, but they shine even brighter when served with a scoop of vanilla ice cream or a dollop of whipped cream on the side. The contrast of cold and warm enhances the flavors and adds a delightful creaminess to each bite. For an extra touch, drizzle some chocolate sauce or caramel over the top just before serving.

Feel free to get creative with the toppings! Chopped hazelnuts or a sprinkle of sea salt can elevate the flavor profile even more. You can also experiment with different types of chocolate chips, such as dark or milk chocolate, based on your preference. Tailoring these brownies allows for endless possibilities to suit different palates!
