Substitute for olive-oil in baking
Quick answer
For most baked goods, substitute neutral vegetable oil or canola oil 1:1 for olive oil. If you want a closer flavor match in savory baking (focaccia, herb breads), there's no real substitute — use olive oil or accept a different result.

| Rank | Substitute | Ratio (replaces 1 cup olive-oil) | Notes |
|---|---|---|---|
| #1 | Canola oil | 1:1 (e.g., 1/2 cup canola oil for 1/2 cup olive oil) | The most reliable swap for olive oil in baking. Canola oil is neutral in flavor, has a similar fat content and liquid behavior, and produces the same moist, tender crumb. Works in cakes, muffins, and quick breads without any detectable difference. Not appropriate when olive oil's flavor is load-bearing (e.g., olive oil cake, focaccia). |
| #2 | Vegetable oil | 1:1 (e.g., 1/2 cup vegetable oil for 1/2 cup olive oil) | Functionally identical to canola oil for baking purposes. Neutral flavor, same liquid fat behavior. Most commercial vegetable oils are soybean- or canola-based and behave the same way in batters and doughs. A safe swap when you have nothing else. |
| #3 | Melted coconut oil | 1:1 (e.g., 1/2 cup melted coconut oil for 1/2 cup olive oil) | Works well in muffins and quick breads. Coconut oil solidifies at room temperature, so it can slightly firm up the crumb compared to olive oil — this is noticeable when the baked good is served cold. Refined coconut oil is neutral in flavor; unrefined adds a mild coconut taste. Don't use it in recipes that call for chilling the batter, as it can seize unevenly. |
| #4 | Unsalted butter (melted) | 3/4 cup melted butter for 1 cup olive oil (or scale proportionally) | Butter adds flavor and a slightly richer, denser texture. Widely recommended by King Arthur Baking and America's Test Kitchen as a functional substitute. The water content in butter (roughly 15–18%) means baked goods may brown a bit faster and come out slightly less moist than with oil. Works in a pinch but produces a noticeably different result in very oil-forward recipes. |
Why baking is different
In baking, olive oil functions as a liquid fat that coats gluten strands and contributes moisture, resulting in a tender, moist crumb that stays soft longer than butter-based equivalents. Unlike butter, oil doesn't solidify at room temperature, which is why oil-based cakes and muffins stay tender even when chilled. In recipes where olive oil is the dominant flavor — olive oil cake, focaccia, herb flatbreads — its grassy, fruity notes are a core part of the result, not just a medium for other ingredients.
Common mistakes
The most common error is substituting a solid fat (like room-temperature coconut oil or unmelted butter) without accounting for its different physical state — always melt these before measuring and adding. A second mistake is using a strongly flavored oil (like toasted sesame oil or walnut oil) as a 1:1 swap, which overwhelms most baked goods. Finally, people often reach for a substitute in recipes like olive oil cake where the oil's distinctive flavor is the point; in those cases, no neutral oil produces the same result.
Olive oil’s role in baking is primarily structural and textural: it keeps baked goods moist and tender by interfering with gluten development and by staying liquid at room temperature. For the vast majority of everyday baking — boxed cake mixes, banana bread, muffins, carrot cake — a neutral oil like canola oil is a direct 1:1 swap with no practical downside. The substitution is so clean that Serious Eats and King Arthur Baking both treat neutral oils as interchangeable with olive oil in standard recipes.
Where substitution gets complicated is in recipes built around olive oil’s flavor. An olive oil cake from a trusted source uses olive oil the way a browned-butter cake uses butter — the fat is the flavor. Replacing it with canola oil produces a perfectly acceptable, moist cake that tastes like very little. If you’re in that situation and out of olive oil, it’s better to postpone the recipe than to proceed with a neutral substitute and expect the same result.
Frequently asked questions
- Can I substitute butter for olive oil in a cake recipe?
- Yes, with adjustment. Use 3/4 cup of melted unsalted butter for every 1 cup of olive oil. The texture will be slightly denser and the cake will brown faster. It works, but the result isn't identical — oil-based cakes are typically more moist and stay tender longer.
- Will swapping olive oil for canola oil change the taste of my baked goods?
- In most standard cakes, muffins, and quick breads, no — the flavor difference is undetectable once other ingredients are present. In recipes where olive oil is prominent (olive oil cake, savory herb bread), canola oil will produce a noticeably blander result.
- Can I use applesauce instead of olive oil in baking?
- Applesauce is sometimes used as a low-fat swap, but it changes the texture significantly — baked goods become denser and more gummy. It's not a reliable 1:1 substitute and is not recommended here. If fat reduction is the goal, that's a different optimization than a straightforward substitution.
