Combine your non-dairy milk and apple cider vinegar in a bowl then let it sit for 5-10 minutes. The mixture will start to curdle making a vegan buttermilk
Combine your dry ingredients together then mix. Add in your vanilla, melted vegan butter, and vegan buttermilk.
Using a spatula, gently mix together until combined. It is super important to not overly mix here since this is what helps make the waffles so fluffy! It's okay if there are some lumps, the batter should be thick and easily scoopable.
Preheat your waffle maker then spray a bit of avocado oil on it to ensure the batter doesn't stick.
Once preheated, add anywhere from ¼-1/2 a cup of mixture (depending on how big your waffle maker is) and close and let it cook. Don't open it until the steam has stopped from the waffle maker. I have a mini waffle maker and this recipe makes 6-8 mini waffles (about 3-4 servings).
Enjoy with your favorite toppings, I love berries and maple syrup!
Storage: These are best enjoyed warm but can be stored in the fridge for up to 3 days. Just reheat in the microwave for 30-60 seconds (I like pouring the maple syrup over my waffles when reheating so it gets warm as well).
