Follow these simple steps to whip up a batch of easy waffles without baking powder:

1. Preheat your waffle iron.
   Ensuring your waffle iron is hot will help achieve that perfect crispy outside and fluffy inside.
2. In a bowl, mix flour, sugar, baking soda, and salt.
   This dry mixture forms the base of your waffle batter, setting the stage for the addition of wet ingredients.
3. Create a well in the center and add buttermilk, melted butter, egg yolks, and vanilla. Stir gently until combined (a few lumps are fine).
   The well method helps in mixing the wet and dry ingredients evenly, ensuring a smooth batter consistency.
4. In another bowl, beat egg whites until stiff peaks form.
   Beating the egg whites separately and folding them in later helps in achieving a light and airy texture for your waffles.
5. Carefully fold the egg whites into the batter.
   Gently folding in the egg whites will maintain the airiness, contributing to the fluffiness of the waffles.
6. Lightly grease the waffle iron. Pour batter according to your iron’s instructions.
   Greasing the iron prevents sticking and ensures easy removal of the waffles once cooked.
7. Close and cook until golden brown.
   Cooking times may vary based on your waffle iron, so keep an eye on the waffles until they reach your desired level of crispiness.
8. Remove and serve warm with your favorite toppings like syrup or fresh fruit.
   Enjoy the fruits of your labor with delicious toppings that complement the waffles’ flavor and texture.
