Preheat Oven to 350 Degrees F.

Line 2-3 cookie sheets with parchment paper or a silicone mat

Using a stand mixer on Medium speed cream the butter, sugar and brown sugar for 3-4 minutes

In another bowl, mix the flour, salt baking powder and baking soda

To the mixer add the eggs, pure hazelnut extract and Nutella. Mix for 2-3 minutes

Add the flour mixture slowly and let it combine

Finally add the chopped hazelnuts and chocolate chips. Mix for one minute

Using an ice cream scoop, spoon the cookie dough on the cookie sheet. Keep them well separate so they spread well

Bake for 10-11 minutes until browned. They will still be a tad soft in the middle

Remove from oven and let them cool on a baking rack.
