In a medium sized bowl, whisk flour, cornmeal, salt, sugar, and baking powder.
In a large bowl, stir the oil, sour cream, creamed corn, and eggs until well combined.
Stir the dry ingredients into the wet, just until combined.
Pour the mixture into a 10” cast iron skillet (or 9” square pan that you’ve sprayed with cooking spray). Bake at 375°F for 20-25 minutes.
