Substitute for buttermilk in pancakes: what works
Six buttermilk substitutes for pancakes with exact ratios from America's Test Kitchen, King Arthur and Purdue Extension, plus the one swap to refuse.
Put 1 tablespoon of lemon juice or white vinegar in a measuring cup, fill it to the 1 cup line with milk, and let it stand 5 to 10 minutes. That is the standard buttermilk substitute, and it works in any pancake recipe. For pancakes specifically, America's Test Kitchen prefers a different route: 1 1/2 teaspoons of cream of tartar whisked into the dry ingredients with plain milk as the liquid, because you get the acid without the vinegar flavor.
Buttermilk does two jobs in a pancake: it reacts with baking soda for lift, and its acidity tenderizes the gluten. A substitute with acid but no thickness gives a thinner batter and flatter pancakes, so pick based on whether you want rise or body.
Buttermilk substitutes for pancakes at a glance
| Substitute | Ratio | Best for | Watch out |
|---|---|---|---|
| Milk plus lemon juice or white vinegar | 1 cup minus 1 Tbsp milk plus 1 Tbsp acid, stand 5 to 10 minutes | Any buttermilk pancake recipe | Tang can read as sour. Lemon juice is friendlier |
| Cream of tartar plus plain milk | 1 3/4 tsp per cup of milk (King Arthur, Purdue). ATK uses 1 1/2 tsp for pancakes | Lift with no off flavor | It clumps in milk. Whisk it into the flour |
| Greek yogurt plus milk | 1 part yogurt to 2 parts milk (5.3 oz container plus 1 1/3 cups milk makes 2 cups) | Thick, tall diner-style pancakes | Use whole-milk Greek yogurt |
| Plain yogurt or plain kefir | 1:1, thinned with milk until pourable | Tender, tangy pancakes | Undiluted, the batter cooks unevenly |
| Dried buttermilk powder | 1/4 cup (30g) powder into the dry ingredients plus 1 cup (227g) water | Occasional pancake makers | No resting time needed |
| Plain milk plus a leavening rewrite | Purdue: 1 tsp baking powder equals 1/4 tsp baking soda plus 1/2 cup buttermilk, other liquid cut by 1/2 cup | Rewriting the recipe | Changes flavor along with the rise |
How to swap in a buttermilk substitute for pancakes
- Measure the acid first. Put 1 tablespoon of lemon juice or white vinegar into a 1 cup measure, then top it with milk to the 1 cup line.
- Let it stand 5 to 10 minutes. Purdue Extension gives 5 to 10 and King Arthur says 10 to 15, so you have room. It should look slightly thickened and lightly curdled.
- Whisk the dry ingredients while it rests. Taking the cream of tartar route instead? This is where it goes: 1 3/4 teaspoons per cup of milk into the flour, never into the milk.
- Combine and stop early. Mix only until the flour is wet. Lumps are correct. Overmixed batter cooks tough whatever you used.
- Cook as written. None of these swaps changes pan temperature or timing.
What changes when you use a buttermilk substitute in pancakes
Milk plus vinegar gives you the chemistry without the body. Real buttermilk is thick, and that is part of why buttermilk pancakes sit tall instead of spreading. Acidified milk pours thinner, so expect a wider, flatter pancake.
Flavor is the other difference. ATK is blunt about "the questionable appeal of vinegar pancakes," and in a plain pancake the tang can come through as sour. Cream of tartar avoids the question. ATK's cream of tartar pancakes came out "just as lofty and light as those made with buttermilk, with no off-flavors."
When texture matters more than convenience, Greek yogurt thinned with milk at 1 part yogurt to 2 parts milk is the closest match here. It gives back the body acidified milk cannot.
When not to substitute buttermilk in pancakes
Plain milk with no acid is the one swap to refuse. King Arthur says it outright: do not substitute plain milk in a recipe built on baking soda. Soda needs acid, and without it you get flat pancakes that can taste soapy.
If there is genuinely no acid in the house, rewrite the leavening instead. Purdue Extension runs the equivalence the other way too: 1 cup of buttermilk plus 1/2 teaspoon of baking soda replaces 1 cup of whole milk when the baking powder is cut by 2 teaspoons. Read that backward and you have plain milk with the baking powder put back. It moves flavor along with rise, so treat it as a last resort.
One note on the real thing: cultured buttermilk keeps about two weeks refrigerated, per USDA. That short window is why a quart bought for one Saturday morning goes down the drain. Freezing dairy buys time, and dried buttermilk powder skips the problem at 1/4 cup (30g) powder plus 1 cup (227g) water.

Let your kitchen suggest the buttermilk substitute
Well Stockd's substitution engine reads what is in your kitchen and suggests swaps when a recipe calls for something you are out of. Frozen and canned forms count as matches, and you can reject any suggestion you never want again. If buttermilk is what you keep buying and pouring out, an app to track food expiration dates or a pantry inventory app flags it before the two weeks run out.
Buttermilk substitute for pancakes FAQ
What can I use instead of buttermilk in pancakes?
1 tablespoon of lemon juice or vinegar topped with milk to the 1 cup line, rested 5 to 10 minutes. Or 1 3/4 teaspoons of cream of tartar whisked into the flour, with plain milk as the liquid.
Will pancakes made with a buttermilk substitute taste like vinegar?
They can. America's Test Kitchen flags this, which is why they prefer cream of tartar for pancakes. Lemon juice is the milder acid.
Can I use regular milk in buttermilk pancakes?
Not without adding acid or changing the leavening. Baking soda needs acid to work, and without it the pancakes go flat.
Does Greek yogurt work as a buttermilk substitute in pancakes?
Yes, and the texture beats milk plus vinegar. Use 1 part yogurt to 2 parts milk, whole-milk kind.
