Toasted hazelnuts and chocolate-hazelnut spread star in these sweet, nutty Hazelnut Blondies.

One of my new favorite “holidays” is World Nutella Day, hosted by Sara of Ms. Adventures in Italy. I am a relatively recent Nutella fan, having discovered it a couple of years ago. My love of this delicious chocolate-hazelnut spread was instantaneous, so I am more than happy to celebrate a day dedicated to such a deserving treat.

Hazelnut Blondies feature plenty of toasted hazelnuts and a bit of chocolate-hazelnut spread. A favorite sweet, nutty treat! - Bake or Break

Last year, I celebrated Nutella Day with some delicious no-bake Nutella Oatmeal Cookies. This year’s celebratory treat is a bit tamer and comes to us courtesy of Martha Stewart. They are simple enough to make, as most bar recipes tend to be. My only problem was in finding an 8″x 11″ baking pan. I did eventually find one, but if you don’t have one you should be able to make them in a 9″x 13″ baking pan. They won’t be as thick, but that should be the only real difference. Keep in mind that with thinner bars, your baking time will probably need to be reduced.

These blondies have just a hint of Nutella in them, but are absolutely fabulous with a dollop of it right on top. The toasted hazelnuts are just wonderful. They really intensify the Nutella flavor. Even without the additional Nutella, these blondies are so, so good. The flavor of the brown sugar really comes through without being overwhelming. If you’re a fan of brown sugar, then these are definitely for you. If you’re a bigger fan of Nutella, then spread it on thick and enjoy!

  1. Ooo, nutella and blondies – what a wonderful combination! And what better way to use the lonely bag of hazelnuts sitting in my pantry without purpose…till now!

  2. I’m so bummed I missed this…I love Nutella…and your blondies are to die for.

  3. You are a bake star! And I can vouch for your those brownies. Delish.

  4. i’m a nut for nutella.
    (insert groan here)
    ๐Ÿ™‚

  5. I would have instinctually incorporated nutella into a brownie, not blondie recipe. Subtlety seems smart in this situation, however.

  6. It’s so hard for me to keep Nutella in the house and not eat it all! These look great, even without the Nutella. I love the darker color.

  7. Fabulous photos and recipe; thanks so much for participating in World Nutella Day!

  8. Thanks, everyone!

  9. Mmm, this looks gorgeous. If only I didn’t have a brownie/blondie baking-block… oh well. Love the pictures!

  12. This recipe literally stopped me in my tracks. I was already to scroll on by but my mouse halted mid-scroll.
    These look wonderful and I am excited to find another way to use one of my favorite nuts. Question: Do you think these would work with Brazil nuts?

  13. Indigo, do I even want to know about the baking-block? I couldn’t bear to do without brownies and blondies!

    JEP, it’s divine, isn’t it? How I lived without it all those years, I’ll never know.

    Kate, they’re not meant to be torturous! ๐Ÿ™‚

    Thanks, Sarah! I think this would work with just about any kind of nut. I’ve never baked with Brazil nuts, but it’s certainly worth a try.

  39. Thanks, La’Laila. Nutella is pretty high up there on my list, for sure.

    Golly, if there’s a world peanut butter day, I will definitley be celebrating.

  40. for a chocolate lover this treat is the most beautiful thing that’ll ever happen to them..imagine that gorgeously looking blondies swirled over by nutella…i’m totally in love ๐Ÿ™‚

  41. dhanggit, thank you so much. These were so good. I miss them…. ๐Ÿ˜‰

  42. I just made these this weekend, and they were a huge hit! Definitely one of my favorite desserts already, and it counldn’t have been easier to make. I baked mine in a 9×9 pan, and they turned out perfectly. And I added 1/2 cup bittersweet and 1/2 cup semi-sweet chocolate chips. They were awesome… thanks for introducing me to this fabulous recipe!

  43. Kristin, I’m so glad you liked them! Good to know that they worked well in a 9×9 pan.

  44. Another yummy looking recipe – think I could substitute pecans for the hazelnuts? Would you recommend adding more nutella?

  45. Emily, pecans will work, although the hazelnuts emphasize the Nutella flavor. If you want more Nutella, I would just add more on top.
