Grease a 9-inch round cake pan or square baking dish or cast iron skillet well and set aside.
Preheat the oven to 400 degrees F.
In a medium mixing bowl, add the flour, cornmeal, sugar, salt, and baking powder. Whisk to combine well.
Make a well in the center of your dry ingredients and add your oil or butter, milk, and egg. Stir just until the mixture comes together and there are only a few lumps remaining.
Pour the batter into the prepared pan and bake for 25 minutes until the top is golden brown and a toothpick inserted into the center comes out clean.
Serve hot.
