In a medium sized bowl, whisk together flour, cornmeal, salt, sugar and baking powder.
In a large bowl, stir together 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-inch cast iron skillet (or 8-9” square pan that you’ve sprayed with cooking spray). Bake at 425 degrees for about 25-30 minutes.
Cool for 10-15 minutes before cutting into triangles or squares and serving.
Notes
For muffins, grease a 12-count muffin pan with cooking spray. Divide batter into cups and bake at 425 degrees for about 20 minutes.
