To make waffle batter, mix 1 1/2 cups of flour and 1 1/2 teaspoons of baking powder with a pinch of salt and 1/4 cup of sugar. Whisk together 1 1/2 cups of milk and 2 eggs, and mix them into the dry ingredients. Add 3 tablespoons of melted butter.
To reduce the calories and the sweetness of the mix, use 3 tablespoons of sugar instead of 1/4 cup. Avoid over-mixing the wet and dry ingredients; stir them together only until everything is combined. Change the flavor of the basic waffle batter by stirring in chocolate chips, blueberries or cut fruit.
For thicker, Belgian-style waffles, combine 2 cups flour, 3/4 cups sugar and 3 1/2 teaspoons baking powder. In another bowl, mix 2 egg whites, 1 1/2 cups of milk, 1 cup butter and 1 teaspoon pure vanilla extract. Add them to the dry mixture. Pour 2 egg whites into a third bowl, and beat them with an electric beater until they reach the stiff-peak stage. Stir the egg whites gently into the batter.
If your waffles have a doughy texture, your batter may be too thick. Mix in additional milk, 1 tablespoon at a time, until the batter thins out.
