Take them out of the oven and let them cool off completely.
In a large bowl, cream the butter, coconut sugar, and vanilla extract. For best results, use an electric mixer.

Start incorporating the flour mixture into the wet ingredients.
In a food processor, pulse the hazelnuts until roughly chopped.
Using a wooden spoon or spatula, fold in the oats, chocolate chips, and ground hazelnuts.
Using a cookie scoop or a spoon, scoop out the cookie batter and form cookie dough balls.
Place them on a baking sheet or baking tray lined with parchment paper.
Bake cookies for about 15 minutes, or until golden brown and have crispy edges.

Once cool, they will become more crispy.
