Preheat oven to 350 degrees.
Generously grease a 9 x 13 inch baking pan or a 12 inch cast iron skillet.
Sift the dry ingredients into a large bowl.
Smooth the batter into the baking pan or skillet and bake for 25 to 30 minutes, or until a knife inserted into the center comes out clean.
Allow the corn bread to cool for at least 10 minutes before serving.
