Preheat oven to 350 degrees. Line a large rimmed baking sheet with parchment paper or a silpat.

In a medium bowl, whisk flour, baking soda and salt. Set aside.

In the bowl of a stand mixer, cream butter and sugars until creamy and smooth. Beat in egg and vanilla extract until combined. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in chocolate chips.

Take a scoop of dough and flatten in the palm of your hand. Add 1 Tbsp of Nutella into the center of each cookie. Carefully roll the dough over the Nutella, adding more dough as needed, so it is a large cookie ball. Make sure the Nutella is covered.

Bake cookies for 14 minutes, until browned on the edges and still soft in the center. Let cookies cool for 10 minutes in the pan before placing on a cooling rack.
