Preheat the oven to 425 F. Grease an 8-inch square baking pan. Place the dry ingredients in a large bowl. Add the milk, egg and melted butter and beat for about 1 minute, or until the mixture is smooth. Add bacon; mix well. Pour the batter into the square pan, place in the oven and bake for 20 minutes, or until the corn bread is lightly browned on the top and a toothpick inserted into it comes out clean. Makes 12 pieces. Fried Corn Bread: Split 4 to 6 pieces leftover corn bread. Heat 2 tablespoons bacon drippings in a heavy cast-iron skillet over medium heat. Place the split corn bread pieces in the drippings and fry until lightly browned on both sides. Serve hot with butter and jam. Makes 4 servings.
