Yes, you can substitute buttermilk with dairy or non-dairy options if you match the same acidity and liquid in your recipe.
Run out of buttermilk right before you mix biscuit dough or pancake batter? You are not alone. Many home cooks ask can i substitute buttermilk? when a recipe calls for it and the fridge shelf is empty.
The good news is that you have several simple ways to copy the tang, tenderness, and moisture that buttermilk gives to baked goods and savory dishes. This guide walks through why buttermilk matters, which substitutes come closest, and how to swap without wrecking texture or flavor.
Can I Substitute Buttermilk? Basic Answer And Rules
The short answer is yes, you can substitute buttermilk in most recipes as long as the swap matches two things: acidity and liquid. Store buttermilk is slightly thick, tangy, and acidic, so your replacement needs to be close on those points.
When a recipe uses baking soda, that acidity matters even more because the two react to create lift. If you replace buttermilk with plain milk and skip the acid, your muffins or cakes may rise less and feel dense. On the other hand, if you add too much acid and not enough liquid, the batter can taste sharp and look curdled.

How Buttermilk Works In Recipes
To swap buttermilk with confidence, it helps to know what it does in a bowl of batter or dough. Most store buttermilk is made by adding friendly bacteria to low fat milk, which thickens the liquid and gives a gentle tang.
The acidity softens gluten strands in flour, so baked goods feel tender instead of tough. That same tang also feeds baking soda and helps it release gas, which gives height to pancakes, corn bread, and many cakes.
Buttermilk also carries some protein, calcium, and other nutrients found in dairy. The current Dietary Guidelines for Americans list dairy foods as a steady source of calcium and vitamin D, which matters if you bake with dairy often.
On top of structure and nutrition, buttermilk gives gentle lactic flavor. That tang balances sweetness in baked goods and helps batter based fried chicken or fish brown nicely in hot oil.
Substituting Buttermilk In Everyday Cooking And Baking
Different recipes lean on buttermilk in different ways. Some mainly need the acid, some use the thickness for body, and some rely on that gentle sour note. Pick a substitute that mirrors what the dish needs most.
Pancakes, Waffles, And Breakfast Bakes
For breakfast batters, the classic mix of milk plus lemon juice or vinegar usually works well. Stir one tablespoon of acid into a cup of milk, wait ten minutes so it thickens a little, then use it as you would buttermilk. Many baking teachers, including King Arthur Baking, share this ratio for reliable results.
If you like tall, fluffy pancakes, pair that milk and acid mix with a recipe that uses baking soda. The combination helps batter puff on a hot griddle and keeps the crumb light.
Biscuits, Scones, And Quick Breads
Biscuits and scones need both acid and a bit of richness. Milk plus plain yogurt is a great choice here. Stir equal parts yogurt and milk until smooth, then use cup for cup in place of buttermilk.
For savory soda bread or cheese biscuits, thinned sour cream works too. It brings more fat, which leads to tender crumbs and crisp edges. Just make sure the mixture is pourable so the dough does not feel stiff.
Cakes, Cupcakes, And Brownies
Cake recipes that use buttermilk often chase a fine crumb and a mild tang. Thinned yogurt, thinned sour cream, or kefir all stand in well. If the cake calls for both buttermilk and oil, you can sometimes swap part of the oil for extra yogurt to keep the batter moist.
When baking chocolate cakes or brownies, buttermilk helps deepen cocoa flavor. A blend of sour cream and milk delivers that same depth. Avoid very sweet flavored yogurts here, since added sugar can throw off the balance of the recipe.
Savory Marinades And Dressings
Buttermilk based marinades coat chicken and fish, tenderising the surface and helping seasonings cling. For this kind of dish, plain yogurt thinned with water works well, as does kefir. Both cling nicely to meat and stand up to time in the fridge.
For creamy salad dressings, thinned sour cream or Greek yogurt blended with a splash of milk gives the tang and body that buttermilk would bring. Taste the mix with salt, pepper, garlic, and herbs before you dress the salad.

Comparing Dairy And Dairy Free Buttermilk Substitutes
Each stand in has its own strengths. Some match the tang of buttermilk, some copy the thickness, and some are mainly there to keep the recipe flexible for people who avoid dairy.
| Substitute | Taste And Texture | Best Uses |
|---|---|---|
| Milk + Acid | Thin, mild tang | General baking, quick breads, pancakes |
| Yogurt + Milk | Thicker, gentle tang | Biscuits, scones, richer cakes |
| Thinned Sour Cream | Rich, creamy, strong tang | Chocolate cakes, dense loaf cakes |
| Plain Kefir | Pourable, tangy, slight fizz | Pancakes, waffles, snack cakes |
| Dairy Free Milk + Acid | Thin, tang depends on brand | Dairy free bakes and pancakes |
| Buttermilk Powder + Water | Close to real buttermilk | Mixes, waffles, stored dry mixes |
Buttermilk Substitute Mistakes To Avoid
It is easy to stir acid into milk and call it done, but a few small missteps can spoil a pan of batter. These tips keep your swap from causing dense or sour results.
- Do not skip the resting time. Milk needs several minutes with the acid so the mix thickens and curdles a little. Pouring it in right away dulls the effect.
- Match fat levels. If a recipe uses whole milk buttermilk and you replace it with skim milk plus lemon juice, the crumb may feel dry. Use milk with a similar fat level or add a spoon of melted butter or oil.
- Watch sugar and flavorings. Flavored yogurts and sweetened plant milks can throw off the balance in cakes and breads. Plain, unsweetened products keep things predictable.
- Adjust salt a little. Some dairy products and buttermilk powders include added salt. Taste the substitute and reduce salt in the recipe by a pinch if it seems salty.
- Do not push swaps in sensitive recipes. Very light sponge cakes or recipes that rely on whipped egg whites may not respond well to big changes in liquid and acid. Use real buttermilk for those when you can.
Buttermilk Substitute Cheat Sheet For Busy Cooks
When you need a fast answer to can i substitute buttermilk? think about what your recipe really needs. If it needs a sour note and extra lift, milk plus lemon juice does the job. If it needs richness, use yogurt, sour cream, or kefir thinned to a pourable state.
