Preheat oven to 350

In medium bowl, whisk together flour, salt and baking soda. In a separate bowl, with electric mixer, beat the butter and sugar until creamy. Then beat in the egg and the vanilla extract. Now add the flour mixture to the butter mixture and beat until blended. With a wooden spoon, mix in the chocolate chips.

Press cookie dough evenly into a medium cast iron skillet. You need to use an oven safe pan (even the handle needs to be oven safe).

Bake for about 25 minutes on center rack, until edges begin to brown and the top is light golden brown. Let cool in pan.

Serving Suggestion: These are awesome just as they are, but would be even more awesome topped with your favorite ice cream when they are still warm.
