Preheat your oven to 400°F (200°C).
In a mixing bowl, combine cornmeal, flour, sugar, baking powder, and salt.
In another bowl, whisk together milk, vegetable oil, and egg.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Heat a skillet over medium heat and grease it lightly.
Pour the batter into the skillet and spread it evenly.
Bake in the preheated oven for 20-25 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
Let it cool slightly before slicing and serving.
