Preheat the oven to 375°F. In a mixing bowl, combine all the dry ingredients. Add the cheese and toss to combine. Add the beer all at once, mixing as little as possible just until blended; the batter should be lumpy. Pour the batter into a 4"x8" or 9"x5" loaf pan that has been sprayed with nonstick spray, and brush with the melted butter or oil. Bake in the oven for 40-45 minutes, or until a skewer poked into the middle comes out clean. Turn out onto a rack to cool.
