To begin, preheat your oven to 375 degrees. Place your 8-inch skillet into the oven to heat while you prepare the batter.
Stir together dry ingredients in a mixing bowl.
In a separate dish, whisk the eggs, milk, and oil together.
Add the liquid to the dry ingredients and stir with a fork or whisk until just combined.
Remove your hot skillet from the oven and spread a tablespoon of butter all inside the skillet. Pour in your batter and spread it fairly level.
Bake 20-25 minutes, until golden brown and a toothpick inserted into the center comes out clean.
Enjoy!
Notes
If you do not have a small cast iron skillet, you can bake this in an 8 inch square baking pan. The cornbread will likely bake for a shorter period of time, so check it around 15-20 minutes.
You can substitute 2 Tb honey for the sugar. If you do that, add the honey with the liquid ingredients.
