1 Preheat oven to 400°F. Grease a 8x12 inch baking dish.
2 In a large bowl mix the cornmeal, flour, salt, baking powder and baking soda. In a separate bowl, beat the softened butter and sugar. Beat the sour cream and eggs to the butter sugar mixture. Add the milk and the dry ingredients, a third at a time and alternating wet/dry. Mix in the green chiles, corn, and shredded cheese. Pour mixture into prepared baking dish.
3 Bake for 35 minutes, or until top is browned, the center springs back when pressed down, and a skewer inserted into the center comes out clean. Let cool almost completely before serving.
