This chocolate chip skillet cookie is soft, gooey, and packed with melty chocolate. Baked in a cast iron skillet, it gets crispy edges while staying chewy in the center.
Heat your oven to 350°F (175°C). Grease an 8-inch (20 cm) cast-iron skillet with butter or nonstick spray.
In a medium bowl, use a hand mixer or stand mixer to beat the softened butter, brown sugar, and granulated sugar until fluffy (about 2-3 minutes).
Beat in the egg and vanilla until fully mixed. In another bowl, whisk together the flour, baking soda, and salt. Slowly add this to the wet mixture, stirring until just combined. Don’t overmix.
