Cream butter, granulated sugar, and brown sugar together with an electric mixer for 3 minutes until light and fluffy.

Beat in Nutella, egg, and vanilla until combined.

Whisk flour, baking soda, and salt in a separate bowl, then gradually add to the wet mixture, mixing on low just until no flour streaks remain.

Fold in chocolate chips with a spatula.

Preheat oven to 350°F. Scoop 2-tablespoon dough balls onto parchment-lined baking sheets, spacing 2 inches apart. Bake 10-12 minutes until edges are set but centers look soft.

Cool on the pan for 5 minutes, then transfer to a wire rack. Serve warm.
