Step 1: Preheat the Waffle Iron. Begin by preheating your waffle iron according to the manufacturer’s instructions.
Step 2: Combine the Dry Ingredients. In a mixing bowl, whisk together the all-purpose flour, kosher salt, sugar, baking powder, and baking soda until well combined.
Step 3: Mix the Wet Ingredients. In another bowl, combine the buttermilk, egg, melted butter, and vanilla extract. Whisk until the mixture is smooth and well blended.
Step 4: Combine Wet and Dry Ingredients. Pour the wet ingredients into the bowl with the dry ingredients. Gently fold the mixture together using a spatula.
Step 5: Cook the Waffles. Lightly grease the preheated waffle iron and pour the recommended amount of batter onto it. Cook until golden brown and crispy.
Step 6: Serve and Enjoy! Carefully remove the waffles and serve immediately with your favorite toppings.
