lightly grease the cast iron skillet with butter and press the cookie dough down into the skillet
bake the cookie for about 15-20 minutes. The sides should be browned and the center will be a little raw and jiggly still. That's ok!!! DONT OVER COOK IT
remove the hot cast iron skillet from the oven and let it sit for 10 more minutes. The heat from the skillet will continue to cook the cookie.
add the ice cream, whipped cream and whatever other toppings you'd like to.
