I like to use a combination of the two. Buttermilk gives these waffles the best flavor, while milk helps produce a lighter texture. Yogurt is a great substitute for milk in waffles: simply use equal parts of yogurt to replace the milk in the recipe, then prepare it accordingly and you'll get soft, fluffy waffles. So if you're wondering, “Can I make buttermilk waffles with regular milk? You can, but it's not the same thing.
Thanks to its distinctive characteristics, buttermilk is the perfect choice for adding delicious flavor and moisture to waffles. Start your day with a hot cup of coffee and homemade buttermilk waffles and all will be well in the world. The combination of buttermilk and baking soda will help the waffles rise and be thick and fluffy.
