Preheat oven to 375 degrees F. Grease an 8-inch cast iron skillet with butter and heat in oven.
In a large bowl whisk eggs with corn kernels. Stir in flour, cornmeal, baking powder and salt. Stir in milk and oil until just combined. Do not overmix. Remove skillet from oven and pour in batter. Bake until golden, about 25 minutes. Cool slightly before slicing and serving.
