These cookies are slightly crispy on the outside, but with a moist and dense chocolaty center. Loaded with lots of chocolate chips and hazelnuts, Chocolate Hazelnut Cookies taste very much like eating a big spoon of Nutella in cookie form!
Preheat oven to 350 degrees. Line a baking sheet with a silicone baking mat or parchment paper. Set aside.
In a mixing bowl, use a hand-held mixer to beat together the butter and the sugar until well combined.
Add the eggs and vanilla extract. Beat into the butter and sugar mixture.
Sift together the flour, cocoa powder, baking soda, and salt. Add it to the wet ingredients and mix until well incorporated.
Next, stir in 1 cup of mini milk chocolate chips and 1 cup of the chopped toasted hazelnuts.
Portion out 1 heaping tablespoon of the cookie dough. Roll into a ball and place onto the prepared baking sheet.
With the palm of your hand, flatten the cookie ball to just under half of an inch thick. Top the cookie with a few of the remaining milk chocolate chips and chopped hazelnuts.
Repeat until you have used up all of the cookie dough, leaving two inches of space between each cookie.
Bake for 12 minutes. Remove from oven and allow to cool on baking sheet for 5 minutes. Transfer cookies to a wire cooling rack to finish cooling.
