Decadent, gooey, and packed with a delicious mix of chocolate and hazelnuts, these brownies turn basic items into a mouthwatering treat. The mix of Nutella with toasted hazelnuts builds multiple layers of nutty goodness that works perfectly with the thick, dense texture you want in top-notch brownies.

I whipped these up for my family reunion last week, and my dessert-avoiding aunt begged me for the instructions. Everyone rushed to the kitchen when they smelled those hazelnuts toasting, way before the brownies were done.

Key Ingredients and Smart Shopping Advice

  • Unsalted Butter: Go for European-style since it has less water and makes tastier brownies
  • Nutella: Let it sit out until soft so it mixes into your batter without lumps
  • Cocoa Powder: Dutch-processed gives you darker brownies with smoother chocolate taste
  • Hazelnuts: Pick ones that feel heavy and full without any wrinkles
  • Vanilla Extract: Real extract works way better than fake stuff to bring out chocolate flavors

Step-by-Step Guide

Toasting the Hazelnuts:
Start by toasting your hazelnuts at just 275°F, which seems low but works better. This slow roast brings out amazing flavor without burning. When your kitchen starts smelling fantastic, you'll know they're getting good.
Removing Hazelnut Skins:
Be patient with the towel-rubbing method for skin removal. Try doing small batches while the nuts are still warm. Don't stress if some skins stay on - they'll add a bit of rustic charm to your brownies.
Butter and Sugar Mixture:
The butter-sugar mix should feel slightly warm when touched, not hot. This temperature trick stops your eggs from cooking when added and helps create that shiny top everyone loves.
Egg Addition:
Adding eggs one at a time isn't just being fussy - it actually makes an emulsion that's crucial for fudgy texture. Wait until each egg disappears into the batter before adding another, and watch how it gets shinier each time.
Mixing in Dry Stuff:
Stop folding right when you can't see flour anymore. Mix too much and you'll get cakey brownies instead of fudgy ones because of gluten forming.

My grandma always told me "you can't rush good brownies." She taught me to wait until they're totally cool before cutting, no matter how good they smell. Now I hear her reminding me to be patient whenever I bake them.

Extraordinary Brownie Experience

I've learned texture makes these brownies special. The way the slightly crunchy top contrasts with the dense, fudgy middle creates something you won't forget. Your first bite breaks through that crackly surface before sinking into the rich chocolate-hazelnut center with bits of toasted nuts throughout.

Finding the Right Portion

I've figured out that cutting into 16 pieces rather than 12 gives you the perfect size. These brownies pack so much richness from the Nutella and toasted hazelnuts that smaller squares let people enjoy them without feeling stuffed.

Temperature Makes a Difference

These brownies change character depending on how you serve them. Cold from the fridge, they're almost like truffles. At room temp, they hit that perfect fudgy sweet spot. Slightly warmed, they turn wonderfully gooey and melty.

Smart Storage Tricks

I've found putting a slice of bread in the container with these brownies keeps them at just the right moisture level. The bread stops them from drying out or getting too dense. Just swap out the bread every couple days for a fresh slice.

After tons of brownie batches over the years, I've found these chocolate hazelnut ones nail the balance between fancy and comforting. Good ingredients handled with care make brownies that work for special events but are also perfect for everyday snacking.

Impressive Gift Ideas

These make fantastic presents - just wrap single squares in parchment and stack them in a nice tin. I've given these as Christmas gifts and people always ask when they'll get more.

Party Serving Suggestion

For get-togethers, try setting up a build-your-own brownie bar. Serve warm brownies with options like:

  • Heated Nutella for drizzling
  • Fresh whipped cream
  • Crunchy toasted hazelnuts
  • Flaky sea salt
  • Rich chocolate sauce

Wrapping Up

These chocolate hazelnut brownies show what I love most about baking - how simple stuff handled with care turns into something amazing. Whether you're a pro or just starting out, these brownies prove that mixing classic methods with special touches creates truly memorable treats.

Always remember, the tastiest brownies come from taking your time and paying attention to details. Happy baking!

Adjusting for Different Results

Every oven works a bit differently, so knowing yours matters for brownie success. In my fan-forced oven, I lower the heat by 25°F and check about 5 minutes early. You're aiming for that slightly underbaked middle that turns perfectly fudgy once cooled.

Ideas for Every Season

Summer: Enjoy them cold with fresh raspberries and mint leaves

Fall: Serve alongside warm spiced apple cider

Winter: Pair with orange-flavored hot chocolate

Spring: Top with lavender-infused whipped cream

Flavor Building Secrets

Creating distinct taste layers makes these brownies so good. The toasted hazelnuts add three separate flavor elements:

  1. The obvious crunch and nutty taste
  2. A gentle oil that soaks into the batter
  3. A roasted smell that boosts the chocolate flavor

Quick Fixes

Even good bakers sometimes need rescue tactics:

  • If they're a bit overcooked, brush some warm Nutella on top
  • Too soft in the middle? Stick them in the fridge for 30 minutes before cutting
  • Edges too crunchy? Cut them off and sprinkle them over ice cream

Giving as Gifts

When sharing these brownies as presents, presentation counts:

  • Put parchment paper between layers
  • Add a note with storage tips
  • Use metal tins instead of plastic containers for better freshness

Expert Baking Insights

Listen to how the batter sounds when poured - you want a thick, slow-moving consistency

The top should look set but still have a tiny wobble in the middle

Letting the batter sit for 30 minutes before baking actually makes flavors stronger

These brownies aren't just food - they're proof of how everyday ingredients can become something special. Each batch teaches me something new about balancing flavors and textures for the ultimate brownie experience.

Frequently Asked Questions

→ Do I have to use hazelnuts?
Nope, you can leave them out, but they do give a great crunch and up the nutty flavor.
→ How can I tell they’re ready?
Pierce the center with a toothpick. It should come out almost clean, but a little chocolate smudge is fine for fudgy texture.
→ Can I put these in the freezer?
Totally. Just wrap them tightly, and they’ll stay good in the freezer for up to 3 months. Defrost in the fridge overnight.
→ Why toast the hazelnuts first?
It makes the nuts taste much better by bringing out their natural oils.
→ Where should I store them?
Keep them in a sealed container at room temp. They’ll stay fresh for around 5 days.

Ingredients

→ Base Ingredients

01 3 large eggs
02 1 cup unsalted butter
03 1 cup sugar
04 4 ounces semisweet chocolate, chopped
05 2 teaspoons vanilla extract
06 ⅓ cup Nutella (chocolate hazelnut spread)
07 1¾ cups semisweet chocolate chips, split into two portions

→ Dry Ingredients

08 ½ tablespoon baking powder
09 ¼ teaspoon salt
10 1¼ cups hazelnuts, coarsely chopped, split into two portions and toasted
11 ⅔ cup all-purpose flour

Instructions

Step 01

Heat oven to 325°F. Line a square 9-inch baking pan with parchment paper, making sure there’s about a 2-inch edge hanging over all sides. Lightly coat it with nonstick spray.

Step 02

In a medium pot over low heat, stir together the butter, 4 ounces chopped chocolate, and 1 cup chocolate chips. Keep mixing until smooth, then set aside to cool down.

Step 03

In a big mixing bowl, beat together the eggs, Nutella, sugar, and vanilla until well combined. Slowly mix this into your warm chocolate mixture.

Step 04

Combine flour, baking powder, and salt by sifting them together. Mix this dry blend into your chocolate batter. Then, fold in the rest of the chocolate chips and 1 cup toasted hazelnuts.

Step 05

Pour the batter into the prepped pan and scatter the other half of the hazelnuts on top. Bake for 40 minutes, then loosely cover with foil and bake another 10 to 15 minutes until mostly set. Let it cool fully before slicing.

Notes

  1. Wait until it’s fully cool to slice cleanly.
  2. Toothpick won’t come out clean because they’re fudgy!
