Yes, you can replace buttermilk with yogurt in almost any recipe by thinning the yogurt with milk or water to match the consistency.
Running out of ingredients mid-recipe happens to the best home cooks. You have the flour, the baking soda, and the eggs, but that carton of buttermilk is missing or expired. If you have a tub of plain yogurt in the fridge, you have the perfect solution. Yogurt shares the same fermented, acidic properties that make buttermilk essential for baking, making it a reliable 1:1 swap once you adjust the texture.
This guide breaks down exactly how to thin different types of yogurt, the chemistry behind why this substitution works, and how to adjust your approach for pancakes, marinades, or cakes.
Why Yogurt Works As A Superior Substitute
Understanding the role of buttermilk helps you see why yogurt fills the shoes so well. Buttermilk is not just about flavor; it serves a structural purpose in baking. It contains lactic acid, which reacts with baking soda to create carbon dioxide bubbles. These bubbles cause batters to rise and become fluffy.
Yogurt is also a cultured dairy product rich in lactic acid. Because the acidity levels are similar, yogurt triggers the same chemical reaction with leavening agents. Unlike plain milk, which lacks acidity, yogurt ensures your pancakes puff up and your biscuits stay tender. The only significant difference lies in viscosity. Commercial buttermilk is thicker than milk but pourable, while yogurt is spoonable and dense. Fixing that texture is the only step standing between you and a saved recipe.
The Golden Ratio: Thinning Yogurt Correctly
You cannot swap thick yogurt directly for liquid buttermilk without throwing off the moisture balance of your dough. If the batter is too dry, the result will be tough. You must dilute the yogurt to mimic the pourable nature of buttermilk.
Standard Yogurt Method
For regular, plain yogurt (not Greek), the consistency is already somewhat loose, so it requires less liquid to reach the right state.
- Measure the yogurt — Spoon 3/4 cup of plain yogurt into a measuring cup.
- Add liquid — Pour in 1/4 cup of milk (whole or 2%) or water.
- Whisk thoroughly — Stir until the mixture is smooth and pourable.
- Use immediately — This yields one cup of buttermilk substitute.
Greek Yogurt Adjustments
Greek yogurt is strained to remove whey, making it much thicker and higher in protein. It requires a heavier hand with the thinning liquid to reach the correct consistency.
- Adjust the ratio — Use 2/3 cup of Greek yogurt and 1/3 cup of milk or water.
- Check the flow — Whisk and lift the spoon. It should flow off easily, similar to heavy cream.
- Add more liquid — If it clumps or holds its shape, add water one tablespoon at a time until it runs smooth.
Using water works fine if you want to keep the calorie count neutral, but thinning with milk preserves the richness and fat content, which leads to a more tender crumb in baked goods.
Can I Replace Buttermilk With Yogurt In Baking?
Baking is precise chemistry. When you ask, “Can I replace buttermilk with yogurt in baking?” the answer depends heavily on the type of fat in the yogurt. Buttermilk usually contains some fat (unless you buy fat-free), which coats flour proteins and prevents gluten development. This results in soft textures.
Using a non-fat yogurt diluted with water removes that fat element. For the best baking results, use whole-milk yogurt diluted with whole milk. This maintains the fat percentage needed for moist cakes and muffins. If you only have non-fat yogurt, consider adding a teaspoon of melted butter or oil to the mixture to compensate for the missing lipids.
The acidity in yogurt also helps tenderize gluten. This is why this swap is particularly effective in recipes like soda bread or scones, where overworking the dough usually leads to a rock-hard result. The yogurt buys you a little insurance against toughness.
Best Use Cases For The Yogurt Swap
While this substitute is versatile, it shines in specific culinary scenarios. Knowing where it performs best helps you decide when to use it.
Pancakes and Waffles
Yogurt is arguably better than buttermilk for breakfast batters. The thick consistency of yogurt-based batter holds air bubbles effectively. When the heat hits the batter, the acidity reacts instantly with the baking soda.
According to King Arthur Baking’s guide on leavening, the balance of acid and base is what determines the final lift. Yogurt provides a robust acidic kick that results in distinctively tall, fluffy pancakes with a pleasant tang.
Marinades for Chicken and Meat
Buttermilk fried chicken is a classic because the enzymes and acids break down protein fibers, making the meat tender. Yogurt does this even faster. In Indian cooking, yogurt is the standard marinade for tandoori dishes for this exact reason. Its thickness allows it to cling to the meat better than buttermilk, ensuring flavor penetrates deep into the muscle fibers.
Salad Dressings
Ranch and creamy herb dressings often call for buttermilk to provide a tart, creamy base. Yogurt works here, but you should be careful with thinning. If you want a dip, leave the yogurt thick. If you want a pourable dressing, thin it slightly less than you would for baking—aim for a ratio of 4 parts yogurt to 1 part milk. The flavor will be slightly tangier, which usually improves the profile of a fresh salad.
Flavor Profiles: What To Expect
Substitute ingredients often alter the taste. Regular buttermilk has a distinct, buttery tang. Yogurt has a sharper, more acidic bite. In baked goods with sugar, cocoa, or vanilla, this difference is undetectable. The sugar balances the tartness, and the heat mellows the flavor.
In savory recipes like biscuits or cornbread, you might notice a slightly fresher taste. It rarely clashes with savory flavors; instead, it tends to brighten them. Be wary of using vanilla-flavored yogurt. While it works in sweet cakes, the added sugar and vanilla extract will ruin savory dishes like fried chicken or ranch dressing. Always stick to plain, unflavored varieties for versatility.
Troubleshooting Common Issues
Even with a simple swap, things can go sideways if you ignore the details. Here are a few hiccups cooks encounter and how to fix them.
The Batter Is Too Thick
If your muffin or cake batter looks like bread dough, you didn’t thin the yogurt enough. Add milk one tablespoon at a time until the batter relaxes. Thick batter prevents steam from escaping, leading to dense, gummy centers.
The Mixture Curdled
If you add hot melted butter to cold yogurt, it will seize and look chunky. This is a temperature shock. Bring your yogurt to room temperature before mixing it with other fats. If you are in a rush, microwave the yogurt mixture for 10 to 15 seconds—just enough to take the chill off, not enough to cook it.
The Taste Is Too Sour
Some Greek yogurt brands are exceptionally tart. If you are making a delicate vanilla cake and fear the sourness will overpower it, increase the vanilla extract slightly or add a pinch more sugar. In pancakes, maple syrup usually masks this entirely.
Other Dairy Alternatives
If you open the fridge and find neither buttermilk nor yogurt, you still have options. The goal remains the same: add acidity to milk.
The Milk and Vinegar Trick
This is the oldest trick in the book. It mimics the acidity but lacks the thick body of buttermilk or yogurt.
- Measure milk — Pour just under one cup of milk.
- Add acid — Stir in one tablespoon of white vinegar or lemon juice.
- Wait — Let it sit for 5 to 10 minutes until it looks curdled.
This works for lift (rising) but provides no richness. Yogurt is a better choice if you want moisture.
Sour Cream
Sour cream is essentially a higher-fat version of yogurt. It is an excellent swap for rich cakes and coffee cakes. Treat it exactly like Greek yogurt: thin it with water or milk until it matches the consistency of buttermilk. Because of the high fat content, it makes baked goods incredibly moist.
Kefir
Kefir is a drinkable fermented milk drink that is almost identical to buttermilk in texture. You rarely need to thin it. You can use it as a direct 1:1 substitute. It has a strong probiotic count and a yeastier flavor profile, but it performs beautifully in quick breads.
Dietary Adjustments and Non-Dairy Options
For those avoiding dairy, the yogurt swap still works if you use plant-based alternatives. However, the protein and fat structures differ.
Coconut Yogurt
Coconut yogurt is high in fat and works well in baking. It is often thinner than dairy yogurt, so you may not need to add much liquid. Watch out for the strong coconut flavor, which may not suit savory biscuits.
Almond or Soy Yogurt
These tend to be lower in fat and thinner. They provide the necessary acidity for the baking soda reaction. If baking a cake, add a teaspoon of neutral oil to the batter to ensure the crumb remains soft.
According to FDA nutrition guidelines, plant-based yogurts vary wildly in additives and thickeners. Avoid brands heavily stabilized with gums (like xanthan or guar gum) for this specific swap, as they can create a gummy texture when heated.

Frequently Asked Questions
Can I use flavored yogurt as a substitute?
You can use vanilla yogurt for sweet recipes like pancakes or waffles, but you must reduce the sugar in the recipe slightly. Never use fruit-flavored or vanilla yogurt for savory dishes like fried chicken, biscuits, or dressings, as the sweetness will clash with the salt and spices.
Does yogurt make pancakes fluffy like buttermilk?
Yes, yogurt often makes pancakes even fluffier. The thick consistency helps the batter hold its shape in the pan, while the acidity reacts vigorously with the baking soda to create significant lift. Many cooks prefer the yogurt texture over traditional buttermilk for breakfast items.
Can I use Greek yogurt without thinning it?
Only in very specific recipes like heavy coffee cakes or muffins where a dense batter is expected. For most recipes calling for buttermilk, using undiluted Greek yogurt will result in a batter that is too dry and difficult to mix, leading to a tough final product.
Is the measurement exactly 1 to 1?
The total volume is 1:1, but the composition is different. You substitute one cup of buttermilk with a mixture that equals one cup. That mixture is part yogurt and part liquid. Do not just swap a cup of solid yogurt for a cup of liquid buttermilk.
What if I only have heavy cream?
Heavy cream lacks the acidity needed to activate baking soda. If you use cream, you must add acid. Mix the cream with a tablespoon of lemon juice or vinegar to sour it. This mimics the fat content and acidity of buttermilk better than cream alone.
Wrapping It Up – Can I Replace Buttermilk With Yogurt?
Yogurt is arguably the most effective substitute for buttermilk available in a standard kitchen. It replicates the tangy flavor, the acidic chemical reaction, and the creamy texture needed for high-quality baking and cooking. By mastering the simple dilution ratio—roughly three parts yogurt to one part liquid—you can swap these ingredients with total confidence.
Whether you are whipping up a Sunday morning batch of pancakes or marinating chicken for dinner, this substitution saves you a trip to the store without compromising the quality of your food. Keep a tub of plain yogurt on hand, and you effectively always have buttermilk ready to go.
