Preheat oven to 400° F and grease a 6-well muffin tin with nonstick cooking spray.
Whisk together the flour, cornmeal, sugar, baking powder, and salt in a medium size bowl. Add oil, egg, and milk. Stir just until lumps are gone.
Pour evenly into the prepared pan and bake for 15 to 20 minutes, or until golden brown on top.
