Begin by scooping small dollops of Nutella (about 1 teaspoon each) onto a parchment-lined baking sheet. Pop these into the freezer for 30 minutes to firm up; this ensures a perfect melty center when baked.

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

Beat in the eggs, one at a time, ensuring each is well incorporated. Then, stir in the vanilla extract.

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.

Gradually add the dry ingredients into the wet mixture, stirring gently until just combined. If you're using chocolate chips, fold them in.

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Take a tablespoon of cookie dough and flatten it in your palm. Place a frozen dollop of Nutella in the center, then wrap the dough around it to form a ball.

Space the stuffed cookie balls on the prepared baking sheet, leaving about 2 inches between each.

Bake for 10-12 minutes, or until the edges are lightly golden.

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Enjoy your warm Nutella Stuffed Cookies straight from the oven or let them cool to room temperature.
