Substitute for yogurt in frosting
Quick answer
Sour cream is the most reliable 1:1 swap for yogurt in frosting — same tang, similar fat content, and it holds structure without thinning the mixture. If you need something thicker and richer, use 3/4 the amount of full-fat cream cheese thinned with 1–2 tsp of milk per 1/2 cup called for.

| Rank | Substitute | Ratio (replaces 1 cup yogurt) | Notes |
|---|---|---|---|
| #1 | Sour cream | 1:1 (e.g., 1/2 cup sour cream for 1/2 cup yogurt) | Sour cream matches yogurt's fat content and lactic tang almost exactly in frosting. It's slightly thicker than most yogurts, which actually improves spreadability and helps the frosting hold its shape at room temperature. Works well in both cream cheese-style frostings and whipped frostings that call for yogurt as a tang component. The flavor difference is minimal — most tasters can't distinguish the two in a finished frosting. |
| #2 | Full-fat cream cheese | 3/4 cup cream cheese + 1–2 tsp whole milk per 1 cup yogurt called for | Cream cheese delivers tang and fat, but it's much denser than yogurt — using it straight will make the frosting stiff and heavy. The small addition of milk loosens it to a workable consistency. This substitute results in a noticeably richer, more stable frosting that holds piped shapes well, but the flavor skews more neutral-dairy than tangy. Best in recipes where yogurt was providing body as well as tang. |
| #3 | Full-fat Greek yogurt | 1:1, but drain for 10–15 minutes in a cheesecloth if the recipe uses regular yogurt | If the recipe specifies regular (thin) yogurt and you only have Greek yogurt, use it 1:1 — the extra thickness is a net positive in frosting. If you do have regular yogurt but the frosting is coming out loose, straining it briefly solves the problem. The flavor is identical. This is only listed separately because the swap direction (regular → Greek) is more common than the reverse, and using thin regular yogurt in a recipe developed with Greek yogurt will noticeably slacken the frosting. |
| #4 | Crème fraîche | 1:1 (e.g., 1/2 cup crème fraîche for 1/2 cup yogurt) | Crème fraîche has a higher fat content than yogurt (roughly 30% vs. 3–10%) and a milder, less sharp tang. The result is a slightly richer, smoother frosting with a more subtle sour note. It works well in European-style frostings or anywhere you want creaminess over brightness. Works in a pinch but noticeably shifts the flavor profile toward mellow rather than tangy. Less widely available than sour cream, which does the same job with a closer flavor match. |
Why frosting is different
Frosting is an uncooked application where yogurt's moisture content is directly exposed — there's no oven to evaporate excess liquid. Using a substitute with too much water will thin the frosting immediately and make it weep or slide off the cake over time. Yogurt in frosting typically serves two functions: adding tang to offset sweetness and contributing a small amount of fat for body, so a good substitute needs to cover both roles. Stability at room temperature is the critical constraint that separates frosting from baked-good applications.
Common mistakes
The most common mistake is swapping in low-fat or nonfat yogurt (or its substitutes) — reduced-fat dairy has more water and less fat, which causes the frosting to go runny and fail to hold on the cake. A second frequent error is using liquid-heavy substitutes like thinned sour cream or buttermilk without adjusting the powdered sugar upward to compensate for the added moisture. Start with the substitute at the stated ratio, then assess consistency before adding more liquid or sugar.
Yogurt appears in frosting recipes most often in two situations: tangy cream cheese-style frostings where it offsets sweetness, and lighter whipped frostings where it adds body without the heaviness of pure butter or cream cheese. In both cases the fat content and moisture of whatever you swap in matters more than in baked applications, because nothing is going to cook off.
Sour cream covers the majority of cases without adjustment. If your recipe uses a significant quantity of yogurt — more than 1/4 cup — and you’re substituting with anything slightly thinner or wetter than the original, add powdered sugar 1 tablespoon at a time until you get back to the right consistency before spreading or piping.
Frequently asked questions
- Can I use plain regular yogurt instead of Greek yogurt in frosting?
- Yes, but expect a looser frosting. Strain the regular yogurt through a cheesecloth for 15–20 minutes to remove excess whey before using it. This brings the thickness closer to Greek yogurt and prevents the frosting from becoming runny.
- Will a yogurt substitute change how long the frosted cake keeps?
- Sour cream and cream cheese have similar shelf lives to yogurt under refrigeration, so storage time (2–3 days covered in the fridge) stays roughly the same. Crème fraîche is similarly stable. The bigger risk is forgetting that any dairy-based frosting should not sit unrefrigerated for more than 2 hours.
- Can I leave out the yogurt entirely in frosting without a substitute?
- Only if the yogurt is a minor component (2 tablespoons or less) added purely for tang. In that case, a small squeeze of lemon juice (1/2 tsp) can approximate the brightness. If the yogurt is 1/4 cup or more, it's providing moisture and body that the frosting needs — omitting it without a substitute will result in a dry, stiff, or poorly emulsified frosting.
