If you've never made your own vegan buttermilk before, my simple recipe is easy! Whether you're lactose intolerant, vegan, or just need a lighter option for your dietary needs, my guide is going to show you exactly how to make buttermilk with almond milk and lemon juice.
What Is Buttermilk?
Traditional buttermilk has a long history in baking and cooking. Originally, it was the tangy tasting liquid left behind after churning butter, but today’s store-bought commercial buttermilk is cultured with lactic acid bacteria to achieve the same flavor.
Buttermilk is most often used in baked goods and pancakes to help tenderize gluten, add moisture, and react with a leavening agent to create fluffy textures. It's also sometimes used in marinades too.
Buttermilk vs. Milk in Baking
If you've ever wondered why some recipes call for buttermilk instead of regular milk, the difference lies in their acidity and how they interact with other ingredients.
- Acidity & Leavening: Buttermilk has a slight acidity, which reacts with baking soda or baking powder to help baked goods rise, creating a lighter and fluffier texture. Regular cow's milk and plant milk lacks this acidity and won’t produce the same chemical reactions.
- Texture & Moisture: The tangy, slightly thick consistency of buttermilk adds tenderness and moisture to baked goods. Using plain milk may result in a drier or denser texture unless adjustments are made.
- Flavor Impact: Buttermilk provides a subtle tangy flavor that enhances pancakes, biscuits, and cakes, while other milks tend to have a more neutral taste.
Homemade Vegan Buttermilk
The good news is that you can easily replicate buttermilk’s tangy flavor and creamy texture using plant-based ingredients. By adding an acidic ingredient like lemon juice, apple cider vinegar, or white vinegar to almond milk, you create a reaction that curdles the milk to mimic regular buttermilk.
Plus, this homemade vegan substitute is not only easy to prepare but is lower in calories and low fat compared to any store-bought version of dairy buttermilk.

- Avoid flavored almond milk: Stick with plain unsweetened almond milk to maintain the right taste and consistency.
- Use Different Milk: If you have a nut allergy feel free to use any type of non-dairy milk like soy milk or rice milk. Vegan buttermilk oat milk is popular too.
Storage
If you make more than you need, storing almond milk buttermilk is simple:
- Fridge: Store leftover buttermilk in an airtight container like a mason jar for up to 3 days for later use. Just give it a shake before use.
- Freeze: Pour into ice cube trays for easy portioning, freeze, and then store in a freezer bag. Then just take the non-dairy buttermilk cubes out of the freezer as needed.
