Hazelnut Blondies

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!
