Preheat oven to 400 degrees F. Spray or lightly grease a 9-inch round cake pan or springform pan.

In a large bowl, combine flour, cornmeal, sugar, salt, and baking powder. Stir in egg, milk, and vegetable oil until well combined. Pour batter in to prepared pan.

Bake in preheated oven for about 20-25 minutes, or until a cake-tester inserted into the center of the bread comes out clean.
