Preheat waffle iron.
Whisk together in large bowl:
1 3/4 cup flour
1 T. baking powder
1 T. sugar
1/2 t. salt
Thoroughly blend in a separate bowl:
3 eggs
1/2 to 2 sticks butter, melted (this affects crispness of waffle and size of waistline)
1 1/2 cup milk
Make a well in center of dry ingredients, and pour in wet ingredients. Combine with a few swift strokes of the whisk. If desired, may gently stir in any of the following:
1 cup sharp cheddar, shredded (4 oz.), 3/4 cup finely chopped bananas, 3/4 cup fresh or thawed strawberries, blueberries or raspberries, 1/2 cup of any of these: raisens or any finely diced soft dried fruit, finely chopped toasted walnuts or pecans, crumbled cooked crisp bacon, or 1/4 cup flaked dried coconut.
Belgian waffle makers cook very quickly. Check at 3 minutes. Serve immediately to retain crisp texture, or keep in warm oven directly on rack. Makes 4 - 5 small waffles. They are very filling.
Serve as savory or sweet.
