Hazelnut Chocolate Chip Cookies

Total Time:
1 hr 15 min
30 min
45 min

4 dozen

  • 1/2 cup old-fashioned oats
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsalted butter, room temperature
  • 1 cup (packed) light brown sugar
  • 1 cup sugar
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 4 ounces English toffee candy (recommended: Heath or Skor bar), finely chopped
  • 1 cup hazelnuts, toasted, husked, and chopped
  • 1 (12-ounce) bag semisweet chocolate chips

Preheat the oven to 325 degrees F.

Line 2 heavy large baking sheets with parchment paper. Finely chop the oats in a food processor. Transfer the oats to a medium bowl. Mix in the flour, baking powder, baking soda, and salt. Set aside.

Using an electric mixer, beat the butter and sugars in a large bowl until fluffy. Beat in the eggs and vanilla. Add the flour mixture and stir just until blended. Stir in the toffee, hazelnuts, and chocolate chips.

For each cookie, drop 1 rounded tablespoonful of dough onto sheet, spacing 1-inch apart (do not flatten dough). Bake until the cookies are golden (cookies will flatten slightly), about 15 minutes. Cool the cookies on the baking sheets for 5 minutes. Transfer to a cooling rack and cool completely. (The cookies can be prepared 1 day ahead. Store airtight at room temperature.)

    My wife loves these cookies, I did not have Hazel nuts so I substituted a fairly large Jalapeno pepper. It sounds odd but the hint of hot pepper was nice, and the heat was neutralized. This recipe makes delicious cookies they are good warm or cooled.
    These are my husband favorite cookies! Since there's a candy bar in recipe I cut back on both sugars to 1/2 cup each & I added 1 more tea of vanilla. I flatten down the dough a little before baking & only baked for 9 minutes. One of our local stores sells this cookies for $7.99 a doz. Great recipe
    Followed the recipe and came out perfect.
    Followed recipe exactly except only used 1/2 cup of white sugar, because of a couple of reviews that mentioned the cookies being to sweet. Instead of cutting back on the sugar, I should have just made the cookies smaller if I was afraid they might be to sweet because the cookies turned out perfectly, but they needed that 1/2 cup of sugar. The texture of the cookie and the amount of cook time was perfect. I took them out at exactly 15 minutes, even though they didn't look done. I'm not a big fan of hazelnuts so next time I going to use pecans instead while including 1 cup of white sugar.
    Every year I get, "So, you're making those cookies, right?!"
    Great cookies. I just made them with my 4y.o. son. Super easy. I skipped the hazelnuts, my husband doesn't care for nuts. Follow the recipe and bake them for 15-18 min and the cookies will be perfect.
    After reading all of the great reviews, I was anxious to try this recipe. What a huge disappointment -- these cookies are overly sweet. They baked to a point of being almost crispy throughout with very little of that soft, chewiness that I think makes for a good chocolate chip cookie. My nine-year-old son thought they were great, but if allowed, I think he would eat sugar straight from the bag.
    Fabulous recipe! Have made it time and time again. This recipe never disappoints. The cookies always disappear!
    hands down my very favorite cookie to make and to eat. i love to take the time to shell the hazelnuts and roast them. i crack open a beer, turn on some music, and enjoy some "me" time and in turn makes me out to be a super hero baker : i've handed this recipe out countless times!
    These cookies are SO GOOD. They were really easy to make, and my entire family loved them. I think I would prefer them without the oatmeal, but they still tasted amazing. Definitely one of my favorite cookies!
    These cookies were amazing!!! Although I did make one substitution. My real inspiration was the left over nuts I had from a nut clusters bag. There were lots of nut bits and crumbs (mainly almond and pumpkin. I followed everything to a T except I subbed the nut bits and crumbs for the hazelnut. They were seriously fantastic....best cookie I have ever made! Next time I will add a little more of the toffee candy and grind the oatmeal a little more fine. Excellent!!!! Enjoy! You gotta make this one!!!
    Very Yummy cookie. I couldn't find Hazelnuts so I used the toffee plus, Semi Sweet and Milk Chocolate chips.
    This recipe is perfect. The timing and is wonderful. I also made one batch leaving out the toffee and added more dark choc chips and it was wonderful.
    I followed the recipe carefully but made a few test cookies - which is ordinary practice for me. The cookies spread and were too thin, reminding me of a time when my son and his friends baked chocolate chip cookies and "forgot" to add half of the flour. I ended up adding close to 1/2 cup of flour before the cookies looked good and had a decent consistency (more dough. I was fairly disappointed with this receipe since I've always liked her recipes.
    Wow, what a great cookie! Basically a chocolate chip recipe with the awesome addition of the toasted hazelnuts and toffee. It's a keeper!
    These are DELICIOUS!!! I usually sub macadamias for the hazelnuts, but they are always a huge hit & disappear very quickly!
    Simply amazing! Made this recipe a few times now and recieved nothing but compliments! My favorite cookie recipe by far!
    Just made this recipe-soooo yummyyy! I only used 1cup of the brown sugar (not used the other cup of sugar,only 1/2 cup butter and very few chocolate chips.
    the best ever, I make the batter and freeze in cookie scoop portions. Pop in the oven any time you want a quick treat
    I made several different cookies from the most popular christmas list and these were the best. Everyone LOVED them. Tomorrow is Valentines Day and one of my co-workers is begging me to make them again. Of course I could eat a few myself so no objections here. THESE ARE AMAZING!
    I used less white sugar and chocolate chips because they sounded like they might be too sweet for my taste and they turned out perfectly! These are the first cookies I've made from scratch since I was a kid, and I don't have a mixer so I mixed it by hand and I am so happy with them. I can't wait to have my boyfriend and coworkers try them!
    hubby says these are "the bomb!"...best he's ever had,....and he's had alot!!...i didn't change a thing!..thanks g!!
    Very delicious cookie. I would add a little more butter next time and a little less sugar, but the toffiee and hazelnuts in chocolate chip cookies was great.
    followed directions exactly and I am not sure why... but they came out looking like pancakes. Dont know if I did something wrong. Too sweet. Yeah, so its not happening. Will not make again, wasted my time and money and now Im just a SOURpuss
    I'm never buying cookies pre-made again. This was delicious!
    Absolutely delicious!! I used walnuts instead of hazelnuts because they're cheaper, and i did use the skor bars. I used semi-sweet guittard chocolate chips. I even won our church bake contest with these. don't tell ; Everyone always wants the recipe, and it pleases kids and adults alike.
    So good!!
    Made these for work and everyone loved them. I could not find hazelnuts so used chopped pecans and they were still yummy. After I made the batter I refridgerated it so I could freshly bake them to take to different places during the holiday season. Going to bake more of the batter tonight, nothing like fresh cookies from the oven!
    I have been searching forever for the best chocolate chip cookies. In the past, they've come out too thin, too thick, too crunchy, too cakey, etc. These are perfect!! My search is over. Thank you, Giada!
    This cookie is FAB!! Everyone who tastes them loves them and wants me to make them again, and again, and again. It would be helpful, however, to know to easily husk the hazelnuts...
