Preheat your oven to 400°F. Lightly grease a 9-inch round cake pan.

In a large bowl, whisk together the flour, cornmeal, sugar, baking powder, and salt.

Add the milk, vegetable oil, and egg to the dry ingredients. Whisk until just combined, being careful not to overmix.

Pour the batter into the prepared pan, smoothing the top with a spatula.

Bake in the preheated oven for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean. Let the cornbread cool slightly, then serve it with butter or honey, if desired.
