Preheat your oven to a sizzling 400°F (200°C).
In a large bowl, carefully whisk together the cornmeal, granulated sugar, and oil until thoroughly combined.
Incorporate the eggs and buttermilk into the mixture until everything is perfectly blended.
Grease a skillet or frying pan with a light coat of oil.
Pour the cornbread batter into the skillet and distribute it evenly across the surface.
Place in the oven and bake for 25 minutes, or until its top is beautifully golden brown.
Remove from the oven and allow to cool for 10 minutes before serving up.
