Instructions

• Preheat your waffle iron according to the manufacturer's instructions; if your iron requires it, lightly grease the cooking surfaces.
• In a large bowl, whisk together 4 cups all-purpose flour, 1 teaspoon kosher salt, 3 tablespoons sugar, and 3 teaspoons baking soda until evenly combined.
• Add 1 cup blueberries to the dry mixture and toss them gently to coat the berries with the flour mixture.
• In a separate bowl, whisk together 4 cups buttermilk, 4 eggs, 1/2 cup (1 stick) melted butter, and 1 teaspoon vanilla extract until blended.
• Pour the wet mixture into the dry mixture and stir gently just until the ingredients are combined and no large dry streaks remain; a few small lumps are fine—do not overmix.
• Spoon or pour the appropriate amount of batter into the preheated waffle iron (use the amount recommended for your iron), close the lid, and cook according to your iron’s instructions until the waffles are golden and set.
• Remove the cooked waffles and keep warm while you finish the remaining batter, repeating the cooking step as needed.
• Serve the waffles immediately with your favorite syrup.
