How to Make Buttermilk with Almond Milk

You can make a dairy-free buttermilk substitute with almond milk by adding lemon juice or vinegar, letting it sit for a few minutes, and then using it in pancakes, biscuits, muffins, quick breads, cakes, dressings, and some marinades.

The easiest ratio is 1 tablespoon of acid for every 1 cup of almond milk substitute. For the most accurate baking measurement, add the lemon juice or vinegar to a liquid measuring cup first, then pour in plain unsweetened almond milk until it reaches the 1-cup line.

This is not cultured dairy buttermilk, and it will not be as thick or rich as the real thing. It is better described as acidulated almond milk. Still, it gives recipes the acidity they need for tang, tenderness, and baking soda reactions, which is why it works so well in many dairy-free baking recipes.

Quick recipe: almond milk buttermilk substitute

Almond milk may not curdle as dramatically as dairy milk or soy milk. That is normal. If it smells lightly tangy and has rested for several minutes, it is ready to use.

Almond milk buttermilk ratio chart

Use this chart when a recipe calls for a specific amount of buttermilk. For best accuracy, put the acid in the measuring cup first, then add almond milk until you reach the total amount listed.

Buttermilk amount needed	Acid to use	How much almond milk?
1/4 cup	3/4 teaspoon lemon juice or vinegar	Add almond milk to the 1/4-cup line.
1/2 cup	1 1/2 teaspoons lemon juice or vinegar	Add almond milk to the 1/2-cup line.
3/4 cup	2 1/4 teaspoons lemon juice or vinegar	Add almond milk to the 3/4-cup line.
1 cup	1 tablespoon lemon juice or vinegar	Add almond milk to the 1-cup line.
1 1/2 cups	1 tablespoon plus 1 1/2 teaspoons lemon juice or vinegar	Add almond milk to the 1 1/2-cup line.
2 cups	2 tablespoons lemon juice or vinegar	Add almond milk to the 2-cup line.

For casual cooking, it is also fine to stir 1 tablespoon of acid into 1 cup of almond milk. For baking, the measuring-cup method is slightly more precise because it keeps the final liquid volume closer to what the recipe expects.

Which acid should you use?

Lemon juice, white vinegar, and apple cider vinegar all work. The best choice depends on the recipe.

Acid	Best for	Flavor note
Lemon juice	Pancakes, muffins, cakes, biscuits, dressings	Fresh and lightly citrusy.
White vinegar	Neutral baking, savory recipes, biscuits, quick breads	The cleanest option when you do not want lemon flavor.
Apple cider vinegar	Pancakes, waffles, rustic muffins, marinades	Slightly fruity and stronger than white vinegar.
Lime juice	Cornbread, savory batters, Mexican-inspired recipes	Works, but the flavor is more noticeable.

For most baking, white vinegar is the most neutral. For pancakes, waffles, and muffins, lemon juice is usually the easiest flavor match.

Step-by-step: how to make buttermilk with almond milk

1. Use plain unsweetened almond milk

Choose plain unsweetened almond milk unless the recipe is clearly sweet and vanilla would be welcome. Sweetened or vanilla almond milk can make biscuits, savory cornbread, ranch dressing, and marinades taste off.

Shake the almond milk well before measuring. Almond milk can separate in the carton, and homemade almond milk separates even more easily.

2. Add the acid first

Add lemon juice or vinegar to your measuring cup before the almond milk. This keeps the total liquid amount accurate, which matters most in cakes, muffins, quick breads, and biscuits.

3. Add almond milk to the measuring line

Pour almond milk into the measuring cup until it reaches the amount of buttermilk your recipe calls for. For example, if the recipe calls for 1 cup of buttermilk, add 1 tablespoon lemon juice or vinegar first, then add almond milk until the liquid reaches 1 cup total.

4. Stir and let it rest

Stir the mixture and let it stand for 5 to 10 minutes. Almond milk may look slightly separated, lightly thickened, or almost unchanged. Do not worry if you do not see big curds.

5. Use it right away

Almond milk buttermilk substitute is best used soon after mixing. Stir it again before adding it to batter, dough, dressing, or marinade.

Does almond milk buttermilk work like real buttermilk?

It works in many recipes, but it is not identical to cultured dairy buttermilk. Real buttermilk has dairy proteins, natural thickness, and a cultured tang. Almond milk has less protein and usually a thinner body, so the finished recipe may be a little lighter, less rich, or less tangy.

Where almond milk buttermilk substitute shines is acidity. In baking, that acidity helps activate baking soda and can improve tenderness in pancakes, muffins, biscuits, and quick breads.

For recipes where buttermilk is a major flavor and texture ingredient, such as buttermilk ranch, buttermilk pie, or old-fashioned buttermilk biscuits, expect a slightly different result. The substitute still works, but it will not taste exactly like dairy buttermilk.

Best uses for almond milk buttermilk

Recipe type	Does almond milk buttermilk work?	Tip
Pancakes	Yes	Use lemon juice or white vinegar and let the batter rest briefly before cooking.
Waffles	Yes	For crispier waffles, make sure the recipe has enough fat.
Biscuits	Yes, with texture differences	Use very cold almond milk buttermilk substitute and do not overmix.
Muffins	Yes	Works well in blueberry, banana, lemon, and cinnamon muffins.
Quick breads	Yes	Good for banana bread, cornbread, pumpkin bread, and zucchini bread.
Cakes and cupcakes	Yes	Use plain unsweetened almond milk so the flavor stays neutral.
Ranch-style dressing	Sometimes	Use dairy-free yogurt or vegan mayo for body because almond milk alone is thin.
Fried chicken-style marinades	Sometimes	Use only in the refrigerator and discard marinade that touched raw meat.
Drinking	No	This is a baking substitute, not a cultured beverage.

For breakfast recipes, this substitute is especially useful in pancakes and waffles. See our guide to the best griddle pans for pancakes if pancakes are your main use. For biscuits, you may also want our guide to the best self-rising flour for biscuits.

Best plant milk for vegan buttermilk substitute

Almond milk is easy to find and has a mild flavor, but it is not the only option. Different plant milks behave differently because they vary in protein, fat, starch, sweetness, and added stabilizers.

Plant milk	How it behaves	Best use
Almond milk	Mild and thin; may not visibly curdle much	General baking, pancakes, muffins, quick breads
Soy milk	Usually thicker and more likely to curdle visibly	Best all-around dairy-free buttermilk substitute for baking
Oat milk	Thicker and naturally sweeter	Pancakes, waffles, muffins, sweet quick breads
Cashew milk	Creamier than almond milk	Cakes, muffins, dressings, richer batters
Coconut milk beverage	Can add coconut flavor	Sweet bakes where coconut flavor works
Rice milk	Very thin	Use only when texture is not critical

For the most neutral result, use plain unsweetened almond milk or soy milk. For the thickest dairy-free buttermilk substitute, soy milk or cashew milk usually gives more body than almond milk.

How to make thicker almond milk buttermilk

Almond milk buttermilk substitute is naturally thinner than dairy buttermilk. That is fine for most pancakes, waffles, muffins, cakes, and quick breads. If you need a thicker version, use one of these options.

• Use less thin almond milk: Choose a plain unsweetened almond milk with a slightly creamier body.
• Use half dairy-free yogurt: Whisk 1/2 cup plain unsweetened dairy-free yogurt with 1/2 cup almond milk and 1 to 2 teaspoons lemon juice.
• Use soy or cashew milk instead: These often create a more convincing dairy-free buttermilk texture.
• For dressings: Use vegan mayo, dairy-free yogurt, or blended cashews for body instead of relying on almond milk alone.

Avoid adding cornstarch, tapioca starch, or flour unless the recipe specifically calls for it. Starch can make a cold buttermilk substitute feel gummy and can change the texture of batters.

Why did my almond milk not curdle?

Almond milk does not always curdle dramatically. That does not necessarily mean you did anything wrong. Almond milk is lower in protein than dairy milk, and many commercial almond milks contain stabilizers that help the drink stay smooth.

If your mixture looks thin, lightly separated, or only slightly grainy, it can still work in baking. The acidity is the most important part for recipes that use baking soda.

• Not enough acid: Use 1 tablespoon lemon juice or vinegar per 1 cup total liquid.
• Not enough time: Let the mixture stand 5 to 10 minutes.
• Very stabilized almond milk: Some brands stay smooth even after acid is added.
• Cold refrigerator almond milk: It may react more slowly. Let it sit a few extra minutes before using.

Can you use almond milk buttermilk for marinating chicken?

You can use almond milk buttermilk substitute as a dairy-free marinade base, but it will not behave exactly like dairy buttermilk. It adds acidity and moisture, but it does not bring the same dairy proteins, thickness, or cultured flavor.

For a simple dairy-free marinade, mix almond milk buttermilk substitute with salt, pepper, garlic powder, paprika, hot sauce, or your preferred seasoning. Add chicken, cover, and refrigerate. Do not marinate raw chicken at room temperature. Discard any marinade that has touched raw poultry unless you boil it for safe use as a sauce.

For temperature checks when cooking poultry, see our guide to the best instant-read thermometers.

Can you make almond milk buttermilk with homemade almond milk?

Yes. Homemade almond milk can be used to make almond milk buttermilk substitute. It may separate faster than store-bought almond milk because it usually does not contain stabilizers, so shake or stir it well before measuring.

To make simple homemade almond milk, soak 1 cup raw almonds overnight, drain and rinse them, blend with 3 to 4 cups fresh water, then strain through a nut milk bag, cheesecloth, or a very clean thin kitchen towel. Use more water for a lighter almond milk and less water for a creamier one.

For equipment help, see our guide to fabric nut milk bags and our guide to the best blenders for smoothies and drinks.

Storage and food safety

Almond milk buttermilk substitute is best used the day you make it. If you have leftovers, refrigerate them in a clean covered container and use within 2 to 3 days. Stir before using because separation is normal.

Do not store almond milk buttermilk substitute at room temperature. Like other perishable foods, it should not sit out for long periods. If it smells sour in an unpleasant way, looks moldy, becomes fizzy, or tastes off, discard it.

Freezing is not ideal because almond milk can separate after thawing. If you do freeze it, use it later in cooked or baked recipes rather than dressings or cold sauces.

Diet and allergy notes

• Dairy-free: This substitute is dairy-free when made with almond milk and lemon juice or vinegar.
• Vegan: The substitute itself is vegan, but the final recipe may not be if it contains eggs, butter, honey, or dairy toppings.
• Nut allergies: Almond milk is not safe for people with almond or tree nut allergies. Use a suitable alternative such as soy milk, oat milk, or rice milk if tolerated.
• Gluten-free: The substitute is usually gluten-free, but check the almond milk and vinegar labels if you are cooking for someone with celiac disease or strict gluten-free needs.
• Protein: Almond milk is much lower in protein than dairy milk or soy milk, so it is not a nutrition-equivalent swap for every diet.

Common mistakes to avoid

• Using sweetened vanilla almond milk in savory recipes: It can make biscuits, cornbread, dressings, and marinades taste strange.
• Expecting thick dairy buttermilk texture: Almond milk usually stays thinner.
• Skipping the rest time: Let the acid and almond milk sit for 5 to 10 minutes before using.
• Adding extra liquid by accident: For exact baking, add the acid first, then almond milk to the measuring line.
• Using it as a drink: This is a recipe substitute, not a cultured beverage.
• Leaving it on the counter: Refrigerate leftovers promptly.
