Ingredients:

  • 2 cups (240g) All-Purpose Flour
  • 2 tbsp (25g) Granulated Sugar
  • 1 tbsp (15g) Baking Powder
  • 1 tsp (5g) Baking Soda
  • ½ tsp (3g) Fine Sea Salt
  • 1 ¾ cups (420ml) Full-Fat Buttermilk
  • ½ cup (115g) Unsalted Butter, melted and slightly cooled
  • 1 tsp (5ml) Pure Vanilla Extract
  • 4 Large Eggs, separated (yolks and whites in separate bowls)

Instructions:

  1. Mise en Place: Preheat the waffle iron according to the manufacturer’s instructions. Separate the eggs into two clean, grease-free bowls.
  2. Combine Dry Ingredients: In the large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. Set aside.
  3. Mix Yolks and Liquid: To the bowl containing the egg yolks, whisk in the buttermilk and vanilla extract until just combined.
  4. Add Fat: Slowly drizzle the slightly cooled melted butter into the yolk mixture, whisking gently until integrated.
  5. Combine Wet and Dry: Pour the wet mixture into the dry ingredients. Whisk only until just combined—a few small lumps are perfectly acceptable. Crucially, do not overmix, or the waffles will be tough.
  6. Whip Egg Whites: Using a hand mixer or stand mixer, whip the egg whites until stiff, glossy peaks form (they should hold their shape when the whisk is removed).
  7. Lighten the Batter: Gently fold about one-third of the whipped egg whites into the main batter mixture to lighten it.
  8. Fold in Remaining Whites: Carefully fold in the remaining egg whites in two additions, using a rubber spatula. Use a 'cut and fold' motion, working quickly but gently, stopping as soon as no streaks of white remain. The batter should look airy and voluminous.
  9. Cook Waffles: Lightly brush the preheated waffle iron with oil or butter (if not non-stick). Pour the batter onto the center of the iron (usually about ½ cup per section, depending on size).
  10. Test for Doneness: Cook for 3–5 minutes, or until the steam stops rising and the waffle is deep golden brown and crisp.
  11. Serve: Remove the waffles and serve immediately, or place them on a cooling rack in a warm oven (around 200°F/95°C) to keep them crisp while you finish the rest of the batch.
