Is buttermilk vegan?

Unfortunately, buttermilk is not vegan. It’s made from fermented milk, which contains dairy and is not vegan. 

But what is buttermilk used for? Is it necessary in vegan baking? 

Buttermilk is typically used to help give baked goods their flavor, texture, and rise. The acidity reacts with leavening agents, like baking soda, creating gas that helps the cakes to rise and stabilize. 

Buttermilk also helps with the tender texture found in cakes, and helps give buttermilk biscuits their classic flavor!

Is there a dairy free substitute for buttermilk?

So far, there is no store bought vegan substitute for buttermilk. I will say, though, that Forager Project’s drinkable Cashewmilk yogurt acts like a non-dairy buttermilk, very similarly to traditional buttermilk. So if you come across a container of that, you can use it in most recipes that call for vegan buttermilk.

That being said, instead of going out to purchase an entire container of dairy free buttermilk, you can simply make however much you need with just the dairy free milk in your fridge in just 5 minutes, and not let anything go to waste.

How long does homemade vegan buttermilk last?

Homemade vegan buttermilk will last 2 to 3 days when sealed in a container or a mason jar in the fridge. But I highly recommend using it immediately for your recipes!

Different acids for your vegan buttermilk recipe:

This vegan buttermilk recipe calls for apple cider vinegar; however you can use a few different other options if that’s unavailable.

At an equal ratio to the ACV, you can use:

  • lemon juice
  • white vinegar
  • white wine vinegar

Can you freeze vegan buttermilk?

Yes, you can absolutely freeze vegan buttermilk! Like regular buttermilk, freezing vegan buttermilk will still preserve the curdles and the acid. Simply pour the vegan buttermilk into ice cube trays and freeze. Then once frozen, place the buttermilk cubes into an airtight container or bag to be store for up to 3 months.

Overview: How To Make Vegan Buttermilk

Much like making homemade buttermilk with dairy milk, vegan buttermilk is just as easy! Here’s how to make this quick vegan buttermilk:

  1. Whisk together the dairy free milk of choice and vinegar.
  2. Set aside to curdle.
  3. Use the homemade vegan buttermilk substitute in your vegan bakingrecipe!

Do I need to use soy milk or almond milk?

So truthfully, soy milk and almond milk are the best dairy free milks to curdle. This is because the proteins found in each of these milks reacts with the acid found in apple cider vinegar or lemon juice.

You will also find that oat milk will curdle, but not as much. These three non-dairy milks (almond, soy, and oat) are the best options. 

Coconut milk will not curdle, as there is no protein in coconut milk. However, just because coconut milk won’t curdle doesn’t mean you can’t use it for vegan cakes and vegan cupcakes! 

The vinegar will still react with the baking soda and create the reaction we’re going for.
