Step 1

Preheat the oven to 350° F and spray an 8" cast iron skillet with baking spray.

Step 2

In a large microwavable bowl melt the 1/2 cup butter in the microwave 30 seconds at a time until fully melted. Add the 1/2 cup brown sugar, and 1/3rd cup granulated sugar to the bowl and either mix with a spatula or a hand mixer on low-medium speed until combined.

Step 3

Add the 1 large egg, 1 tsp vanilla extract and mix lightly to combine. Add in the 1 1/4 cups flour, 1/2 tsp salt, and 1/2 tsp baking soda. Mix until a smooth batter forms. Add in the 1 cup chocolate chips and mix until evenly distributed.

Step 4

Add the batter to the skillet and top with extra chocolate chips. Bake for 35 minutes. The cookie is done when the edges are golden brown. The inside will be slightly gooey. If you want a firmer cookie bake for another 5 minutes.

Step 5

Top with ice cream and serve right away!
