one-pan dark chocolate chunk skillet cookie

Thanks to     http://www.sophistimom.com I've been dying to make this and I did for dessert tonight and it was quit delicious. So Here we go one-pan dark chocolate chunk skillet cookie

1 stick (8 tablespoons) unsalted butter
1/2 cup granulated sugar
1/2 cup light brown sugar
1 teaspoon pure vanilla extract
1 egg
1 1/2 cups unbleached all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon kosher salt
1 cup chocolate chunks

1. Preheat oven to 350 degrees. Melt butter in an 8 inch cast iron skillet set over medium-low heat. Stir in sugars and vanilla and remove from heat. Let rest until pan is warm, but no longer very hot, about 5 minutes.

2. Crack an egg onto the butter and sugar mixture, and use a fork to whisk it well into the mixture. Place flour, baking soda, and salt on top, and very carefully stir into the mixture until smooth and well-mixed. Stir in chocolate chunks. Place in the oven for 15-20 minutes*, or until starting to turn golden on the top and around the edges, but soft in the center. Serve with vanilla ice cream.
