Yes, you can make buttermilk with cashew milk, and it’s actually one of the easiest dairy-free swaps you can pull off in your own kitchen.
All you need is cashew milk, an acid like lemon juice or vinegar, and a few minutes of patience.
The acid gently curdles the cashew milk, giving you that tangy, slightly thickened texture buttermilk is known for.
Whether you’re baking pancakes, whipping up a dairy-free ranch dressing, or marinating chickpeas, this homemade version does the job beautifully.
In this post, we’ll walk through how to make buttermilk with cashew milk, why it works so well, and a few tips so yours turns out perfect every single time.
Why You Can Make Buttermilk With Cashew Milk
You can make buttermilk with cashew milk for a few solid reasons, and they all come down to basic kitchen chemistry:
1. Acid Curdles and Thickens the Cashew Milk
The whole magic of buttermilk comes from acid.
When you add lemon juice or vinegar to cashew milk, the acid lowers the pH and causes the plant proteins to gently clump together.
This is what gives you that slightly thickened, creamy consistency you’d normally get from cultured dairy buttermilk.
So yes, you can make buttermilk with cashew milk simply by letting acid do its thing.
2. Cashew Milk Has a Naturally Creamy Base
Cashew milk is one of the creamiest plant milks out there, which makes it a fantastic candidate for homemade buttermilk.
It has a mild, slightly sweet flavor that doesn’t compete with the tang of the acid.
That neutral base is exactly why buttermilk made with cashew milk blends seamlessly into both sweet and savory recipes.
3. It Mimics the Tangy Flavor Profile of Real Buttermilk
Traditional buttermilk gets its signature tang from lactic acid bacteria during fermentation.
When you make buttermilk with cashew milk using lemon juice or vinegar, you’re recreating that tanginess in a matter of minutes.
The result is a dairy-free buttermilk that tastes remarkably close to the real deal.
4. It Works in Baking and Cooking Just Like Regular Buttermilk
If you’re wondering whether buttermilk made with cashew milk actually performs in recipes, the answer is a resounding yes.
It reacts with baking soda to create lift in pancakes, muffins, and cakes.
It adds moisture and tenderness to baked goods.
And it works as a marinade or dressing base for savory dishes too.
How to Make Buttermilk With Cashew Milk
Making buttermilk with cashew milk takes about five minutes, and the method is dead simple:
1. Measure One Cup of Cashew Milk
Pour one cup of unsweetened cashew milk into a glass jar or bowl.
Unsweetened is key here because you don’t want vanilla or sugar fighting the tangy flavor you’re going for.
2. Add One Tablespoon of Acid
Add one tablespoon of fresh lemon juice or white vinegar to the cashew milk.
Stir gently and let the mixture sit for five to ten minutes.
You’ll notice it start to thicken and curdle slightly, which is exactly what you want when you make buttermilk with cashew milk.
3. Stir and Use in Your Recipe
Give it a quick stir before using.
The texture should be creamy with tiny curds throughout, just like traditional buttermilk.
Use it cup for cup anywhere a recipe calls for buttermilk.
4. Store Any Leftovers in the Fridge
If you make buttermilk with cashew milk ahead of time, store it in a sealed jar in the fridge for up to three days.
Just give it a good shake before using, since separation is totally normal.
Tips for the Best Cashew Milk Buttermilk
A few small tweaks can take your homemade buttermilk to the next level:
1. Use Fresh Acid for the Best Curdle
Freshly squeezed lemon juice or a clean-tasting white vinegar gives you the best results when you make buttermilk with cashew milk.
Skip anything that’s been sitting in the back of the pantry for years.
2. Don’t Over-Stir After Curdling
Once your cashew milk buttermilk has curdled, stir gently.
Over-mixing can break up the curds and thin out the texture.
3. Scale the Recipe Up as Needed
The ratio is one tablespoon of acid per cup of cashew milk.
So if a recipe needs two cups, just double it.
That’s the beauty of buttermilk made with cashew milk; it scales effortlessly.
4. Use It Within the Same Day for Baking
While it keeps for a few days in the fridge, buttermilk made with cashew milk performs best when used fresh.
The curdling and thickening are at their peak within the first hour, which is when it reacts best with baking soda.
