Place a 12" Cast Iron skillet into your oven and turn it on to 425°F to preheat
Sift your flour and measure it out, place the flour into a large mixing bowl
Add in sugar, baking powder, salt, and cornmeal (whisk together)
Melt the butter, while the butter is melting; whisk the two eggs and milk together.
Pour the egg mixture into the dry mix and blend well with a wooden spoon.
Drizzle the melted butter over the mixture and gently mix until just blended.
Remove the cast iron skillet from the oven and pour the cornmeal batter into the sizzling cast iron skillet - this gives you that crispy crusty bottom
Place the skillet in the oven and bake for about 20 minutes, start checking at 15 or 16 minutes. The top will be a lovely golden color and a piece of dry spaghetti will come out with just a few crumbs, when poked in the center of the cornbread for testing.
