How to Make Hazelnut Cookies

• Preheat oven to 350°F. Line 2 baking sheet pans with parchment paper or a baking mat.
• Chop hazelnuts with a knife or pulse in a food processor for a few seconds. 
• In the mixing bowl, sift all-purpose flour, hazelnut flour, salt, and baking powder. Set aside. 
• In the mixing bowl of a stand mixer with a pedal attachment, beat egg and sugar until light and fluffy. This took me about 3 minutes.
• Add vanilla paste or vanilla extract. Mix again. After that, add the flour mixture and mix until all is combined. Add chopped hazelnuts and mix with the spatula. 
• Using a cookie scoop or a regular spoon, scoop balls of dough onto the prepared baking sheet. You can use your hands to form balls if needed.
• Bake cookies at 350°F for 12-15 minutes, depending on the size of the cookie. Your cookies are ready as soon as you see brown on the edges. You can also check with the toothpick if needed.
• Let cookies cool on the baking pan for a few minutes, before moving to the cooling rack to cool completely.
