First, preheat your oven to 350 degrees Fahrenheit. Generously spray an 8 inch round cake pan with nonstick spray.

In the bowl of a stand mixer, add the room temperature butter, sugar, and brown sugar. Beat for 2 minutes, until no clumps of butter remain.

Then, add in the eggs and vanilla. Stir to combine.

Add in the flour, baking soda, and sea salt. Stir until a cookie dough is formed.

Fold in the chocolate chips.

Press half of this mixture down into the prepared pan.

Top with the chocolate hazelnut spread. Leave a little room around the edges without the spread. This will prevent leakage.

Then, spread the remaining cookie dough on top.

Bake for 25 to 28 minutes, or until the edges are golden brown and the middle is set.

Finally, remove from the oven. Allow this cookie pie to cool for 1 hour before cutting into.
