These waffles are a Sunday morning tradition in my house. The tang of buttermilk and the crisp exterior from a hot waffle iron can’t be beat. They’re light, fluffy, and soak up syrup like a dream.

This classic Southern breakfast got its start as a clever way to use tangy, leftover buttermilk. The reaction between the acidic buttermilk and baking soda creates an airy, delicate crumb that’s the hallmark of a perfect waffle. For a truly crisp exterior, a well-seasoned cast-iron waffle iron is worth its weight in gold, locking in steam for a fluffy interior while creating deep, caramelized grooves.

Ingredients

• 2 cups (250g) all-purpose flour
• 2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon fine sea salt
• 2 tablespoons granulated sugar
• 1/4 teaspoon ground nutmeg (optional)
• 2 cups (480ml) full-fat buttermilk, well-shaken
• 2 large eggs, room temperature
• 1/4 cup (57g) unsalted butter, melted and slightly cooled
• 1 teaspoon pure vanilla extract

Instructions

1. In a large bowl, whisk together the flour, baking powder, baking soda, salt, sugar, and nutmeg (if using) until thoroughly combined. This ensures even leavening and prevents clumps.
2. In a separate medium bowl, whisk the buttermilk, eggs, melted butter, and vanilla together until smooth and emulsified. The butter should be cool enough not to cook the eggs.
3. Pour the wet ingredients into the dry ingredients. Using a spoon or spatula, gently stir *just until* no dry flour streaks remain. The batter will be thick and slightly lumpy—this is crucial! Overmixing develops gluten and leads to tough, dense waffles.
4. Preheat your waffle iron according to the manufacturer’s instructions until the ready light glows. Lightly brush the grids with oil or a small dab of butter if your iron is not non-stick.
5. Ladle enough batter into the center of the hot iron to spread slightly (about 3/4 to 1 cup, depending on your iron). Immediately close the lid. Cook until steam production subsides and the iron’s ready light indicates doneness, typically 3-5 minutes. The waffle should be a deep golden brown and crisp to the touch.
6. Carefully remove the waffle with a fork or tongs. Place it directly on a wire rack (not a plate!) to keep the bottom from steaming and becoming soggy. Repeat with the remaining batter, lightly re-oiling the grids as needed.
