Preheat the oven to 350°F (175°C).

Line a baking sheet with parchment paper.

In a mixing bowl, whisk together the flour, baking soda, and salt.

In another bowl, cream the softened butter, granulated sugar, and brown sugar together until light and fluffy.

Beat in the egg and vanilla extract until well combined.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Fold in the Nutella gently with a spatula.

Use a cookie scoop or tablespoon to portion out the dough onto the prepared baking sheet.

Bake for about 10 minutes, or until the edges are lightly golden.
