Preheat oven to 400° F. Butter the iron skillet or 8x8 inch baking dish. In a large bowl, beat together oil, eggs, and buttermilk. Stir in creamed corn. In a separate bowl, stir together flour, cornmeal, baking powder, baking soda and salt.
Add flour mixture to corn mixture; stir until smooth. Pour batter into prepared pan.
Bake in preheated oven for approximately 30 minutes or, until a toothpick inserted into center of the pan comes out clean.
