Preheat your oven to 400°F (200°C) and grease a 10-inch cast iron skillet with 2 tablespoons of oil.

In a large mixing bowl, combine cornmeal, all-purpose flour, sugar, baking powder, and salt. Whisk until well mixed.

In a separate bowl, mix together milk, oil, and eggs until smooth and slightly frothy.

Pour the wet mixture into the dry ingredients and gently stir until just combined, avoiding overmixing.

Transfer the batter to the greased skillet and spread it evenly across the surface.

Place the skillet in the preheated oven and bake for 20-25 minutes or until the top is golden brown.

Remove from the oven, let cool for a few minutes, then cut into wedges and serve warm.
