4 cups unbleached all-purpose flour
1/4 cup granulated sugar
2 tablespoons baking powder
1 teaspoon salt
4 large eggs lightly beaten
3/4 cups vegetable oil
2 cups vanilla yogurt
1 1/2 cups milk
2 cups mashed banana
(optional) 1 cup chopped walnuts ( I have also substituted pecans, which give them more of a rich woodsy flavor - deluxe!!!
Combine the dry ingredients (flour, sugar, baking soda, and salt) in a large mixing bowl. Whisk to combine. Add the eggs and oil and whisk until blended. Stir in the yogurt and milk-mix until smooth. Stir in the bananas and nuts, if using, stir until they are incorporated.
After you are done making the waffle mix, plug in your waffle iron and let your batter rest (for about 5 minutes). Bake according to your waffle iron directions.
