Prepare the Cookie Dough

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or a silicone baking mat.
2. Cream the Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
3. Add the Eggs and Vanilla: Beat in the eggs one at a time, then mix in the vanilla extract. Make sure everything is well combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, mixing just until combined. Be careful not to overmix.
5. Add the Chocolate Chips: Stir in the chocolate chips until evenly distributed throughout the dough.

Prepare the Nutella Filling

1. Scoop Nutella: Use a spoon or a small cookie scoop to portion out 12-16 small dollops of Nutella (about 1 teaspoon each). Place them on a plate or tray lined with parchment paper, and freeze for about 10-15 minutes. This step ensures the Nutella doesn’t melt too quickly during baking.

Assemble the Cookies

1. Shape the Cookie Dough: Roll the cookie dough into balls, about 1 1/2 inches in diameter. Flatten each dough ball slightly in the palm of your hand.
2. Add the Nutella: Place a frozen dollop of Nutella in the center of each flattened dough circle.
3. Seal the Dough: Carefully fold the edges of the dough around the Nutella, sealing it inside. Roll the dough back into a ball, ensuring the Nutella is completely enclosed. Repeat for all cookies.
4. Chill the Dough: Place the cookie dough balls on a baking sheet and chill in the fridge for about 10 minutes. This helps prevent the cookies from spreading too much while baking.

Bake the Cookies

1. Bake the Cookies: Place the chilled dough balls on the prepared baking sheets, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are set but still soft.
2. Cool the Cookies: Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. Enjoy the anticipation as the Nutella center sets into a creamy, gooey filling!
