Making Nutella Cookies is simple. Follow these steps for a delicious outcome:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix Ingredients: In a medium bowl, combine Nutella, granulated sugar, and the egg. Mix until smooth and well combined.
3. Add Dry Ingredients: Sift together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring until fully incorporated.
4. Fold in Extras: If desired, fold in chocolate chips and chopped hazelnuts for added texture and flavor.
5. Shape Cookies: Use a cookie scoop or tablespoon to portion out the dough onto the prepared baking sheet, leaving space between each cookie.
6. Flatten Cookies: Gently press down on each cookie dough ball to flatten slightly for even baking.
7. Bake: Place the baking sheet in the oven and bake for 10-12 minutes or until the cookies are just set but slightly soft in the center.
8. Cool: Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
9. Dust with Powdered Sugar: If you’d like a sweeter touch, lightly dust the cookies with powdered sugar before serving.
