Derby Skillet Cookie
Inspired by Derby-Pie's rich filling of chocolate chips and walnuts, this cast-iron skillet cookie version goes straight from oven to table. Topping the gooey cookie with a scoop of ice cream isn't mandatory but is strongly encouraged.
Leave cookie in skillet. Wrap well with foil. Store at room temperature up to 3 days or in the freezer up to 1 month; thaw before serving.
