Heat the cast iron skillet over high heat. Let the internal temperature of the grill reach 425°F. Turn the direct heat under the skillet off and leave the other burners on high.
Mix all the dry ingredients together with a fork. Add the remaining ingredients and mix well. Using corn oil, coat the cast iron skillet well. Pour the batter into the skillet and grill at 425°F for approximately 20 minutes until golden brown.
