Spicey Corn Muffins

Preheat oven to 375 degrees. Line muffin pan cavities with baking cups. In medium bowl, combine flour, corn meal, sugar, baking powder, salt and, if desired, chili powder. In a separate bowl, combine sour cream, oil and eggs; add to flour mixture and mix just until smooth. Gently fold in cheese, corn, beans, peppers and chilies. Pour batter into prepared pan. Bake 18-20 minutes or until golden brown. Turn out of pan. Serve warm.
