This giant cookie can also be baked over a campfire in a Dutch oven. We recommend dousing the finished cookie with whole milk or a big scoop of vanilla ice cream.

Prepare the dough for Chocolate Chip Cookies and press evenly into a 10-inch cast-iron skillet. If desired, sprinkle with (flaky sea salt). Bake until golden brown, 20 to 25 minutes. Allow to cool slightly, then cut into pieces for serving, or drizzle ½ cup whole milk over the cookie, pass around spoons, and eat warm right out of the skillet.
