Here is my time-tested (since 1979) Buttermilk Waffle Recipe.

 2 cups sifted all-purpose flour
2 Tablespoons sugar
2 Teaspoons baking powder
1 Teaspoon baking soda
½ Teaspoon salt
3 eggs, beaten
2 cups buttermilk
½ cup butter, melted

1. Mix flour, sugar, baking powder, baking soda and salt in a large bowl.

2. Beat the eggs and milk together until blended; add along with the melted butter to the dry ingredients and beat only until batter is smooth.
If batter is too thick, add a few teaspoons at a time of buttermilk until spreadable consistency is achieved.

3. Bake in a waffle iron until crispy.

4. To keep waffles warm, put them on wire racks in a 200-degree oven. Until you're ready to serve them, they'll stay warm enough to melt butter. And if you have to feed kids waffles and can't, just can't, serve them frozen grocery-store waffles, these freeze easily. Just reheat them in a toaster on a light setting, or bake for 3 or 4 minutes at 350°F.
