Preheat the oven to 425 degrees Fahrenheit.
Grease an 8-inch baking pan with butter or cooking spray.
In a medium bowl, whisk together the corn meal, flour, sugar, baking powder and salt.
In a separate bowl, beat together the oil, milk and egg.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Pour the batter into the prepared pan.
Bake for 25-30 minutes or until a toothpick inserted in the centre comes out clean.
Let cool for 10 minutes before cutting and serving.
