Soft and chewy chocolate chip oatmeal skillet cookie bakes up in only minutes in a cast iron skillet and is amazing with a scoop of vanilla ice cream on top!
Preheat oven to 350F. Lightly grease a 9-inch cast iron skillet and set aside.
Place butter and brown sugar in the bowl of a large stand mixer, fitted with a paddle attachment OR in a large mixing bowl with a wooden spoon. Mix on medium speed or by hand until creamy, about 2 minutes. Add egg and vanilla to bowl and mix until smooth.
Combine flour, oats, baking soda, cinnamon, nutmeg, and salt in a separate medium bowl. Add to butter mixture and mix until a soft dough forms. Fold in chocolate chips.
Pat dough in an even layer in prepared pan. Bake skillet cookie at 350F 20-22 minutes until edges are golden-brown (center will still be slightly soft - this is okay)
Allow skillet cookie to cool completely on a wire cooling rack before slicing into wedges and serving with ice cream. Enjoy!
