Equipment
Method
- Pre heat the oven to 350 F.
Nutella Filling
- Using the 2 teaspoon cookie scoop, scoop 16 balls of Nutella onto a parchment lined baking pan.

- Place the baking pan into the freezer, and leave for 30 minutes.

Cookie Dough
- Put the oven racks in the top two positions.
- In your mixing bowl, mix the softened butter, brown sugar, and granulated sugar until creamy.

- Add the vanilla and eggs and mix thoroughly.

- Add the flour, baking soda, and salt and mix.
- Slowly add the rolled oats and stir until blended. The mixture will be very thick, be careful not to overwork your blender.

- Using the large 3 tablespoon cookie scoop, scoop out cookie balls and place them on a lined baking sheet.

- Remove the Nutella balls from the fridge and place them beside your cookie balls.

- One at a time, press a hole in each cookie ball with your thumb and insert a Nutella ball in each cookie then close the cookie ball around the Nutella and form it into a sphere again. Place them on a lined baking sheet spaced a few inches apart.

- Sprinkle some fleur de sel on each cookie.

- Bake for 12 minutes.
- If you are using two cookie sheets, switch them halfway.
- Bake until the edges are slightly browned but the center is still light: this will ensure a soft and chewy cookie,

- After the cookies are cool enough, transfer them to a wire rack to cool fully.
