Preheat oven to 350 degrees Fahrenheit.

In a large bowl cream butter, sugar, vanilla and eggs until fluffy, about 4 minutes. Set aside.

In a smaller bowl, mix flour, baking soda, and salt. Set aside about 3 tablespoons of the mixture.

Slowly add in flour mixture to wet mixture bowl and whisk together. (Do not over mix it.) Once mixture has combined, fold in chocolate chips.

In a well greased 11x7 pan, add half of the cookie dough mixture, spread it over the pan for an even layer. Dollop in round spoonfuls of Nutella evenly over the cookie dough. With the back of a spoon, gently spread Nutella to create an even layer over the cookie dough. Top with the remaining cookie dough mixture. Spread to create an even layer.

Bake for 30-35 minutes, or until the cookie dough is a nice golden brown and a toothpick inserted in the center comes out clean.

Remove from the oven and let cool before cutting and serving.
