Preheat your oven to 400°F.
Prepare a 9-inch square baking pan by greasing it lightly.
In a large mixing bowl, combine the cornmeal, flour, sugar, baking powder, and salt.
Mix well to combine all the dry ingredients.
In a separate bowl, mix the milk, melted butter, and beaten eggs.
Stir until well blended.
Pour the wet ingredients into the bowl with the dry ingredients.
Stir just until everything is combined.
Be careful not to overmix.
Pour the batter into the prepared baking pan.
Bake for 20 to 25 minutes or until a toothpick inserted in the center comes out clean.
