Preheat oven to 400° F. Spray or lightly grease a 9-inch round cake 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 into prepared pan.

Bake in preheated oven for 20 to 25 minutes, or until a toothpick inserted into the center of the bread comes out clean.
