Step 1

Preheat the oven to 350F and coat a cast iron skillet with light layer of nonstick spray.

Step 2

In a bowl, whisk together the flour, cornstarch, baking soda, and salt. Set aside.

Step 3

In a large bowl, mix together the butter and sugars using a hand or stand mixer with the paddle attachment. Mix on medium-high speed for 2-3 minutes until light and fluffy.

Step 4

Scrape down the bowl and mix in the vanilla and eggs.

Step 5

Slowly mix in the dry ingredients. The dough will get pretty thick.

Step 6

Switch to a rubber spatula and fold in 1 1/4 cups of the chocolate chips by hand.

Step 7

Press half of the cookie dough into the bottom of the cast iron skillet. If it’s sticking to your hands, spray your fingers with some nonstick spray.

Step 8

Spread the Nutella over top, leaving a 1/2 inch gap around the edge.

Step 9

Take large chunks of the cookie dough and gently flatten them with your hands. Lay them on top of the Nutella layer then press the seems together to create a smooth top.

Step 10

Sprinkle on the remaining 1/4 cup of chocolate chips.

Step 11

Bake for 25-30 minutes for a more gooey cookie and 30-38 for a more well-done cookie. I baked mine for about 28 minutes.

Step 12

If you’d like to just dig in with your spoon, enjoy when it’s warm from the oven. For a cookie you can slice into like a pie, let it cool to room temperature.
