Found this in a magazine, it's easy and good. Add chocolate chips or other special things to make it yours. Milk instead of buttermilk works well too if you get a craving for waffles and have no buttermilk
In a medium bowl, whisk together flour, sugar, baking powder, baking soda and salt; set aside. In a large bowl, whisk together buttermilk, butter and eggs; add flour mixture and mix just until batter is combined.
Heat waffle iron and brush with oil. Pour batter onto iron, leaving a ½ inch border on all sides (spread batter if necessary). Close iron and cook until waffles are golden brown and crisp, 3 - 5 minutes.
Note: Like pancakes, waffles require a gentle hand when preparing batter. For the most tender results, don't over mix it - there should still be some lumps remaining
