A stack of the bars sits in the background.I love cookies, and there are very few varieties that I don’t like. Cookies can be time-consuming though so I decided to come up with a new cookie bar. This Easy Hazelnut Cookie Bar is everything and more than what I expected.

A stack of Hazelnut Cookie Bars sitting on a piece of parchment paper.I was looking through one of my food magazines and saw a macadamia bar that looked interesting. As I always do, I started thinking of the changes that I would make. The filling required you to bring it to a boil and cook it like candy with a thermometer. As delicious as I am sure it is, I just didn’t want to go to all of that trouble.A side view of a hazelnut cookie bar sitting on parchment paper over a wooden background.The only thing these bars have in common with the ones that I saw is that they contain nuts. Not macadamias but hazelnuts because I love them. Just like I love these new bars. They baked up like an ooey gooey chocolate Nutella brownie.
