Preheat your oven to 350°F (175°C).
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract.
In another bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Spread half of the cookie dough into the bottom of a greased 9-inch pie dish.
Spoon the Nutella over the cookie dough, spreading it evenly.
Drop spoonfuls of the remaining cookie dough over the Nutella, covering it as much as possible.
If desired, sprinkle chocolate chips on top.
Bake in the preheated oven for 25-30 minutes or until the edges are golden brown and the center is set.
Allow to cool before slicing and serving. Enjoy your Nutella cookie pie!
