“I think these may be my favorite cookie you’ve ever made.” said my husband AJ, as he eyed another one of my hazelnut oatmeal chocolate chip cookies. This is saying a lot since I bake a lot of chocolate chip cookies. Bakery-style chocolate chip cookies, sourdough oatmeal chocolate chips cookies, classic oatmeal chocolate chip cookies, even crispy chocolate chip cookies. But there you have it. A new favorite cookie!

How do you make these cookies?

These cookies start out with crushing some of the hazelnuts and oats into a powder with a food processor

Then you make some brown butter, which is just cooking the butter until the milk solids start to brown. Mix the brown butter with brown sugar, until it has cooled a bit. Add in vanilla and almond extract.

Then a couple of eggs, baking soda, baking powder, salt, flour and then the powdered hazelnuts and oats.

Stir in the remaining whole rolled oats, chopped hazelnuts and chopped chocolate. Form balls, sprinkle with salt, and bake!

Can I skip the brown butter step?

Yes! Just melt the butter in the microwave (or on the stove) and use that instead.

What type of oats should I use?

Use any type of rolled oats, though I prefer old fashioned rolled oats or thick cut rolled oats. But you can use quick cook, instant or extra thick cut if you want! Keep in mind the thicker the rolled oats, the more texture and chewiness the cookie will be.

Don’t use those packets of instant flavored oatmeal, as those already have sugar and flavoring which won’t work in this cookie. And don’t use pinhead or steel cut oats. Those oats are too thick and will stay raw when you bake these cookies. It will result in a gritty and hard to eat cookie.

Hazelnut Oatmeal Chocolate Chip Cookies

These chunky chewy oatmeal cookies combine thick cut rolled oats, chunks of chocolate chips and hazelnuts. I kind of overloaded the dough with chocolate and hazelnuts so they may seem kind of crumbly when you make the dough. Just “knead” the dough until it comes together with your hands and all will be fine. I made beurre noisette, which is browned butter or, literally translated, hazelnut butter, to bring out the nuttiness in the cookies. But if making brown butter seems too fussy for you, just melt it in a microwave and you’ll be fine.

Equipment

• Food processor

Ingredients

• 1 1/4 cups rolled oats, divided 140 g
• 2 cups hazelnuts, divided 240 g
• 1 1/4 cups unsalted butter at room temperature 285 g or 2 1/2 sticks
• 2 1/4 cups packed dark brown sugar 495 g
• 2 teaspoon vanilla extract
• 1 teaspoon almond extract optional but recommended
• 2 large eggs
• 1 1/4 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1 1/2 teaspoon kosher salt
• 1 1/2 cups all-purpose flour 210 g
• 1 cup 150 g white whole wheat flour (just substitute all-purpose if you don’t have any on hand)
• 10 oz dark chocolate chopped into 1/4 inch chunks
• 1 teaspoon flaky finishing salt like Maldon, Sel de Gris or Diamond Crystal Kosher

Instructions

• Preheat the oven to 350˚F and place a silpat or piece of parchment paper on a baking sheet.
• Place 2/3 cup (about 75 g) of the rolled oats and 2/3 cup (about 90 g) of the hazelnuts in a food processor and pulse until a rough powder forms. Try to get the hazelnuts as fine as possible but don’t worry if there are still some small chunks.
• Place the butter in a medium skillet and cook over medium heat. Stir constantly while cooking, until the butterfat starts to brown and smell nutty. Once you notice some of the butterfat start to brown, turn the heat off and continue to stir, letting the residual heat of the pan brown the butter further. Once it’s golden brown and nutty pour it into the bowl of stand mixer fitted with a paddle attachment. Make sure to scrape all the brown bits into the bowl as well.
  
• Add the brown sugar and beat on medium speed for 1 minutes, cooling the butter down. Once the butter has cooled a bit and the side of the bowl is warm but not hot, add the vanilla and almond (if using) extracts to the bowl. Beat for 15 seconds.

  Add the eggs, one at a time, beating between additions to make sure the egg is incorporated before adding the second one. Add the baking soda, baking powder and salt to the bowl and beat to incorporate.

  Add the flours and beat to incorporate. Add the hazelnut and oatmeal powder and beat to incorporate. Add the remaining rolled oats and beat to incorporate.
• Chop the remaining hazelnuts into small bits (or use your food processor and pulse a few times to get hazelnut chunks). Add the hazelnuts and the chocolate and mix until evenly incorporated in the dough.
• Pinch off some dough and roll a ball about the size of a golf ball (about an 1 1/2 inch wide). Sprinkle a touch of flaky sea salt over the dough ball and repeat with the remaining dough, spacing them 2 inches apart. Bake 16-18 minute or until the cookies brown around the edges and look set. Remove and let cool on the baking pan for 10 minutes before moving them to a wire rack to cool completely.
