A reliable substitute for sour cream when baking is plain, full-fat Greek yogurt, measured in the same amount as the sour cream in your recipe. Its tang and thickness work well in cakes, muffins, quick breads, and many other bakes, though the lower fat in some alternatives can slightly change the texture.
Ingredients
- 1 cup (245 g) plain, full-fat Greek yogurt, unsweetened
Instructions
- Check the yogurt label and choose a plain, unsweetened variety. Avoid flavored or sweetened yogurt, which can add sugar, fruit, or flavorings that interfere with the recipe.
- Spoon 1 cup (245 g) Greek yogurt into a measuring cup. Level it off, then use it in place of 1 cup (240 ml) sour cream. For a different amount, keep the same one-to-one ratio: ½ cup (120 ml) yogurt for ½ cup sour cream, or 2 tablespoons (30 ml) yogurt for 2 tablespoons sour cream.
- If the yogurt has separated, stir it until smooth before measuring. Fold or mix it into the batter at the same point you would add the sour cream, following the original recipe’s mixing instructions.
- Bake according to the original recipe. This substitute does not need cooking or resting on its own; it is ready to use as soon as it is measured and smooth.
Tips
- Choose a thick, full-fat yogurt when possible. Greek yogurt is strained, so it is usually closer in thickness to sour cream than regular yogurt. Full-fat yogurt also brings more richness than low-fat or nonfat versions. If your available yogurt is thin, pour it into a fine-mesh strainer lined with a clean coffee filter or cheesecloth and let it drain in the refrigerator until it thickens. Measure it after draining.
- Keep the swap one-to-one unless the alternative is unusually thin. Using more substitute does not make a cake moister in a predictable way; it can instead make the batter too loose and affect the rise. If using regular plain yogurt, drain it first when it pours like milk rather than falling from a spoon in a thick ribbon.
- Use room-temperature ingredients if the recipe calls for them. Cold yogurt can make softened butter firm up again or cause a batter to mix unevenly. Take out only the amount you need, and follow the recipe’s directions for bringing dairy ingredients to room temperature. Do not leave it sitting out for an extended period.
- Mix gently once the flour goes in. The yogurt’s acidity can react with baking soda, just as sour cream does, but overmixing can still make cakes and muffins tough. Combine wet and dry ingredients only until no dry streaks remain, unless the recipe gives another method.
Serving Suggestions
This substitute is designed to be baked into a recipe, not served as a topping. Use it in the same place the sour cream appears in the ingredient list: in the wet mixture for a cake, stirred into muffin batter, or mixed with other ingredients for a quick bread. It is particularly convenient for recipes where sour cream adds moisture, a gentle tang, and a tender crumb, rather than being the main flavor.
After baking, serve the finished cake or bread as directed by its recipe. A plain yogurt swap is a natural fit for lemon or vanilla cake, banana bread, blueberry muffins, and chocolate cake, where a small change in tang is unlikely to clash with the other flavors. For a savory bake, such as a biscuit or a casserole topping, check that the yogurt is unsweetened and unflavored; Greek yogurt can taste a little sharper and less rich than sour cream.
Variations
Plain whole-milk yogurt: Use 1 cup (240 ml) for every 1 cup (240 ml) sour cream. If it is noticeably thinner than sour cream, strain it before measuring. Regular yogurt is usually less thick than Greek yogurt, so an unstrained swap can make batter looser. Its flavor is pleasantly tangy, but the finished bake may be a little less rich.
Crème fraîche: Replace sour cream with the same volume, such as 1 cup (240 ml) crème fraîche for 1 cup (240 ml) sour cream. It is rich and creamy, with a milder tang, so the baked result can taste less sharp and more buttery. It works especially well in rich cakes and savory bakes, though it may not be the most economical option.
Skyr: Use 1 cup (240 ml) skyr for 1 cup (240 ml) sour cream. It is thick and tangy, making it convenient when available, but many versions are lower in fat. The result can be a little less tender or rich than a bake made with sour cream; full-fat Greek yogurt is a closer choice when richness matters.
Buttermilk, in a pinch: Do not automatically pour in the same amount of buttermilk. It is much thinner than sour cream and can loosen a cake or muffin batter. For a recipe with 1 cup (240 ml) sour cream, start with about ¾ cup (180 ml) buttermilk and reduce another liquid in the recipe by ¼ cup (60 ml), if there is one. This changes the batter’s balance, so it is less dependable than a thick yogurt swap. It is best used when the recipe already has room to adjust its liquid.
Dairy-free yogurt: Use 1 cup (245 g) thick, plain, unsweetened dairy-free yogurt for 1 cup (240 ml) sour cream. Choose a product with a texture close to Greek yogurt and check that it is not sweetened or flavored. Coconut-based yogurt may add a coconut note, while other plant-based yogurts can be milder or thinner; the brand and base ingredient affect the result. A dairy-free sour cream-style product can also work at the same volume if it is intended for cooking or baking.
Cream cheese loosened with milk: For a richer alternative, beat ¾ cup (170 g) softened cream cheese with ¼ cup (60 ml) milk until smooth, then measure 1 cup (about 230 g) of the mixture. It is denser and less tangy than sour cream, so it may produce a heavier crumb. Use it in sturdy cakes or quick breads rather than a delicate batter where the original recipe depends on a light texture.
Storage and Reheating
If you measure more yogurt than you need, return the unused yogurt to the refrigerator promptly in its original container or a clean, covered container. Keep it refrigerated at 40°F (4°C) or colder, follow the package’s use-by guidance, and do not leave dairy at room temperature for more than 2 hours. If you have already mixed the substitute with another ingredient, cover it and refrigerate it; for best quality, use the mixture within 3 to 4 days. Discard it if it has been left out too long or shows an unusual odor, color, or texture.
The substitute itself does not need reheating. Store baked goods according to the original recipe, since storage depends on ingredients such as fruit, frosting, or fillings. For a plain cake or quick bread, follow its recipe’s storage directions and keep perishable toppings refrigerated. To warm a slice, use a microwave in short bursts or a low oven until pleasantly warm; avoid overheating, which can dry it out. If reheating a perishable leftover dish made with the substitute, reheat leftovers to 165°F (74°C).
Frequently Asked Questions
Can I replace sour cream with Greek yogurt in baking at a one-to-one ratio?
Yes. For most cakes, muffins, quick breads, and similar recipes, use the same volume of plain Greek yogurt as sour cream. Choose full-fat yogurt for the closest richness, and stir it smooth before measuring. The recipe should otherwise be followed as written.
Will the finished bake taste like yogurt?
Usually, the flavor is subtle once the yogurt is baked with the other ingredients. Plain yogurt is tangy, much like sour cream, so a slight difference may be noticeable in a recipe where sour cream is a prominent flavor. Avoid flavored yogurt, which can leave a distinct taste and add unexpected sweetness.
Can I use nonfat Greek yogurt?
Yes, but expect a less rich result. Fat contributes tenderness and flavor, so a cake or muffin made with nonfat yogurt may feel slightly drier or firmer than one made with full-fat sour cream. If nonfat yogurt is what you have, it is generally better to use it in a recipe with other sources of fat, such as butter or oil, rather than adding extra liquid or fat without adjusting the recipe.
Is regular yogurt as good as Greek yogurt for baking?
It can work, but regular yogurt is often thinner. If it has a pourable consistency, drain it in the refrigerator until thick before measuring so it does not add too much liquid. Greek yogurt is the simpler option because its thickness is already closer to sour cream.
Can I use lemon juice or vinegar to make yogurt more like sour cream?
Usually there is no need: plain yogurt already has a tangy flavor. Adding extra acid does not reproduce sour cream’s fat or thickness, and too much can make a batter more acidic than intended. Use a thick plain yogurt as the direct swap unless a particular recipe specifically calls for additional acid.
Does this substitution work in every recipe?
It works in many baked goods, but no swap is identical in every formula. Recipes that rely heavily on sour cream for richness, thickness, or a particular texture may come out slightly different with yogurt. For a first attempt at an important bake, use full-fat Greek yogurt and avoid changing other ingredients at the same time.
