Preheat your oven to 400°F (200°C).
In a large mixing bowl, combine cornmeal, flour, sugar, baking powder, and salt.
In another bowl, whisk together milk, vegetable oil, and eggs.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Grease a 9-inch round or square baking pan.
Pour the batter into the prepared pan, smoothing the top.
Bake in the preheated oven for 20-25 minutes, or until golden brown.
Check for doneness with a toothpick; it should come out clean.
Let the cornbread cool slightly before slicing and serving.
