In a large bowl weigh corn meal, flours, sugar and add baking powder and salt. Whisk to combine. In a small bowl whisk the milk, oil, eggs, beer. Add to the dry mixture and stir just to combine (don't overdo it). Add the chilis and fold in. Add the cheese and fold. Pour batter into the prepared hot pan and immediately place in the hot oven. Bake about 15 minutes and check. Rotate and bake about 5 minutes more or just until a toothpick comes out almost clean. Top with chopped cilantro if using. Cool slightly and serve warm, preferably with a nice bowl of chili topped with cheese, sour cream and cilantro. Muy bueno.
