By baking this gigantic cookie in a cast-iron skillet, you achieve those delicious, crunchy, caramelized edges while keeping the warm, gooey, soft center. Top it with classic vanilla ice cream and, in my opinion, it’s the perfect cookie experience. I find having a variety of chocolate types, sizes and textures in the dough makes for a richer, more flavorful cookie. It was gooey, crunchy, decadent and everything else you want a chocolate chip cookie to be. ■ Preheat the oven to 350 degrees and generously grease an 8-, 10- or 12-inch cast-iron skillet with butter.
