14 Substitutes for Buttermilk

You’re halfway into a pancake batter, feeling like a weekend hero… and then the recipe drops the two scariest words in home baking:
buttermilk required. The carton you swear you bought? Gone. The store? Far. Your motivation? Delicate.

Good news: you don’t need to cancel brunch or start Googling “can I cry into waffle iron.” There are plenty of
substitutes for buttermilk that work beautifully in cakes, biscuits, fried chicken marinades, and dressings.
The trick is matching what buttermilk actually does: adds acidity, a little tang, and (often) a slightly thicker texture than plain milk.

What Buttermilk Does (So You Can Fake It Like a Pro)

Cultured buttermilk is mildly tangy and slightly thick. In baking, its acidity teams up with baking soda to create lift,
tender crumb, and that “why is this so fluffy?” vibe. In savory recipes, it brings gentle tang and helps tenderize proteins
(hello, fried chicken). When you swap it, you’re recreating one or more of these jobs: acid, thickness,
and flavor.

Quick Rule of Thumb Before You Substitute

• For baking: Prioritize acidity + similar thickness. Yogurt, kefir, and sour cream mixes shine.
• For pancakes/waffles: Soured milk works, but thicker swaps often taste closer to real buttermilk.
• For marinades/dressings: Kefir or thinned yogurt is usually the closest “buttermilk energy.”
• If the recipe uses a lot of buttermilk: Expect bigger flavor differences. Consider kefir or real buttermilk if possible.

The 14 Best Buttermilk Substitutes (With Ratios + Best Uses)

1) Milk + Lemon Juice (Classic “Soured Milk”)

Add 1 tablespoon lemon juice to a measuring cup, then add milk until it reaches 1 cup total.
Let it sit 5–10 minutes. It’ll look slightly curdledcongrats, you’re doing it right.

Best for: pancakes, muffins, quick breads, cakes. Flavor note: bright tang; a bit sharper than cultured buttermilk.

2) Milk + White Vinegar (Same Trick, Different Acid)

Add 1 tablespoon white vinegar to a measuring cup and fill with milk to 1 cup total. Rest 5 minutes.
This is the fastest buttermilk replacement when your fridge contains milk and your pantry contains… regret.

Best for: baking and quick batters. Flavor note: can taste sharper than true buttermilk in delicate recipes.

3) Milk + Apple Cider Vinegar (A Slightly Sweeter Tang)

Use the same method as white vinegar: 1 tablespoon ACV + milk to 1 cup, rest 5 minutes.
Apple cider vinegar adds a gentler, slightly fruity acidity.

Best for: spice cakes, pumpkin bread, bran muffins. Pro tip: don’t use a strongly flavored vinegar unless you want “vinaigrette cupcakes.”

4) Milk + Cream of Tartar (The Pantry Wizard Option)

Whisk 1 3/4 teaspoons cream of tartar into 1 cup milk. If it clumps, mix the cream of tartar into your
dry ingredients instead, then add the milk as the liquid.

Best for: biscuits, pancakes, muffinsespecially when you’re out of lemons and vinegar feels too aggressive.

5) Plain Yogurt (Straight-Up, If the Recipe Can Handle It)

In many recipes, 1 cup plain yogurt = 1 cup buttermilk. This works best with regular (not super-thick) yogurt.
If it’s too thick to pour, thin it with a splash of milk or water until it looks like a loose batter-friendly liquid.

Best for: cakes, quick breads, tender muffins. Bonus: adds pleasant tang and moisture.

6) Yogurt + Milk (Closer Texture Match)

Mix 3/4 cup plain yogurt with 1/4 cup milk for a pourable substitute. This mimics buttermilk’s consistency better than
yogurt alone.

Best for: biscuits, pancakes, scones, and anything where batter flow matters (aka you don’t want a cement mixer situation).

7) Greek Yogurt + Milk (The Test-Kitchen Favorite)

Greek yogurt is thicker, so it needs more thinning. A reliable approach is roughly 1 part Greek yogurt to 2 parts milk
until it’s pourable and lightly tangy.

Best for: pancakes, waffles, quick breads. Why it works: flavor and body are closer to cultured buttermilk than soured milk.

8) Sour Cream + Water (Simple, Surprisingly Great in Baking)

Whisk together equal parts sour cream and water until smooth and pourable. If your sour cream is extra thick,
add a splash more water.

Best for: coffee cake, biscuits, and tender crumb cakes. Flavor note: rich tang, very “bakery-style.”

9) Sour Cream + Milk (Richer, Softer Results)

Combine 1/2 cup full-fat sour cream with 1/2 cup milk. This is a great buttermilk alternative when you want soft,
fluffy texture (think: cupcakes, snack cakes, shortcakes).

Best for: cakes and biscuits when you don’t mind trading a little tang for extra tenderness.

10) Kefir (The Closest “No-Fuss” Swap)

If you have plain, unsweetened kefir, you’re basically holding buttermilk’s cool cousin. Use it 1:1
in place of buttermilk.

Best for: everythingbaking, marinades, dressings. Pro tip: make sure it’s not flavored unless you want “strawberry ranch.”

11) Buttermilk Powder (The Shelf-Stable Backup Singer)

Buttermilk powder is the “I plan ahead” option. Reconstitute it with water according to the package directions, or
(often) mix the powder into dry ingredients and use water as the liquid.

Best for: biscuits, pancakes, baked goods where you want tang without buying a whole carton of fresh buttermilk.
Heads-up: flavor can be slightly different from fresh cultured buttermilk, but it’s reliable.

12) Dairy-Free Milk + Lemon Juice or Vinegar (Vegan Sour Milk)

Use 1 tablespoon lemon juice or vinegar plus non-dairy milk to 1 cup. Let sit 5–10 minutes.
Some plant milks curdle more obviously than others; soy and almond often behave best.

Best for: pancakes, muffins, quick breads. Tip: choose unsweetened milk to avoid dessert-on-accident.

13) Coconut Milk + Acid (When You Want Rich Dairy-Free Texture)

Coconut milk can be thicker and higher fat, so curdling may be subtlebut you can still use the same idea:
1 tablespoon acid + coconut milk to 1 cup, whisk well.

Best for: tropical or warmly spiced bakes (banana bread, gingerbread, coconut pancakes).
Flavor note: a mild coconut background can be a feature, not a bug.

14) Lactose-Free Milk + Acid (Same Method, Happier Stomach)

If lactose is your nemesis, use lactose-free dairy milk exactly like regular milk:
1 tablespoon lemon juice or vinegar + milk to 1 cup. You’ll get the acidity needed for leavening without the digestive plot twist.

Best for: any baking recipe calling for buttermilkespecially pancakes, muffins, and quick breads.

Common Questions (Because Buttermilk Drama Is Real)

Can I just use regular milk?

Sometimes, but it’s not idealespecially when baking soda is involved. Buttermilk’s acidity helps with rise and tenderness.
Plain milk can leave baked goods flatter, denser, or less flavorful. If the recipe depends on buttermilk, pick a substitute with acid.

Which substitute tastes closest to real buttermilk?

For most people, plain kefir or thinned yogurt gets you closest in both flavor and texture.
Soured milk works in a pinch, but it can taste sharper than cultured buttermilk.

Can I freeze buttermilk so I’m not always in this situation?

Yes. Freeze leftover buttermilk in small portions (even ice cube trays). Thaw in the fridge and whisk if separated.
Future-you will feel oddly powerful.

Conclusion

The best buttermilk substitute depends on what you’re making. For baking, you need acidity and a similar thicknessso
kefir, thinned yogurt, and sour cream mixes are top-tier. For quick fixes,
milk + lemon juice or milk + vinegar will rescue your batter fast. And if you’re dairy-free,
you can still build a reliable buttermilk replacement with the right plant milk and a little acid.

Kitchen Experiences & Lessons Learned (The “ of Reality” Bonus)

The first time I tried a buttermilk substitute, I treated it like a magic spell: one tablespoon of vinegar, one cup of milk,
five minutes of waiting, and voilàinstant Southern grandma energy. Except I forgot one tiny detail: I used balsamic vinegar.
My pancakes came out tasting like a brunch salad. My family was polite in the way people are polite at weddingssmiling while
silently planning their escape.

Lesson one: when a recipe says “vinegar,” it usually means white vinegar (or at least something neutral). Apple cider vinegar
is fine and can be lovely in warm flavors like cinnamon, pumpkin, or bran. But anything aged, sweet, or aggressively “artisan”
should stay far away from your batter unless you truly want to invent a new genre of breakfast.

Lesson two: thickness matters more than you think. Soured milk works, yesbut in biscuits and scones, it can leave the dough
a bit wetter and the results a bit flatter. That’s when Greek yogurt + milk became my go-to. Once you thin it to a pourable
consistency, it behaves like a champ and tastes closer to cultured buttermilk. I’ve also used kefir 1:1 in cupcakes and
wondered why I ever bothered buying buttermilk “just in case.” It’s tangy, it’s pourable, and it makes me feel like I have
my life together (even if I’m wearing mismatched socks).

Lesson three: marinades are their own universe. For fried chicken, soured milk works, but yogurt-based substitutes can cling
better and deliver a more rounded tang. If I’m doing a buttermilk-brined chicken situation, I’ll often choose thinned yogurt
or kefir because the flavor is closer and the texture coats the meat more evenly. The bonus is that you can season it like a
prosalt, pepper, garlic, paprikaand it doesn’t taste like “I panicked and added vinegar.”

Lesson four: non-dairy substitutes are not one-size-fits-all. Some plant milks curdle quickly (soy and almond often behave),
while others barely react, or react unpredictably. That doesn’t mean they won’t workit just means you may not get the same
visual cue. When I make vegan pancakes, I focus less on “did it curdle dramatically?” and more on “did I add acid and did my
batter rise nicely?” Also: check the label for sweeteners. Vanilla-flavored oat milk can be delicious, but it may surprise you
in savory recipes like ranch-style dressings.

The biggest takeaway? Buttermilk substitutes are less about perfect imitation and more about giving your recipe what it needs:
a little tang, a little acidity, and the right consistency. Once you understand the job, you can pick the best swap confidently
and keep cooking without your recipe turning into a dramatic monologue.
