Quick answer

Use olive oil for butter in loaf cakes, muffins, quick breads, and snack cakes when a tender, moist crumb matters more than creaming or crisp edges.

Why it works

Oil keeps cakes moist for days, but it does not aerate like butter, so it is best in simple batters rather than recipes that rely on creaming.

Common Questions

Can olive oil replace butter one-to-one?

Not usually by volume. Butter contains water and milk solids, so the calculator scales the amount.

Will olive oil flavor come through?

Yes, especially in vanilla or lightly flavored bakes. Use a mild oil for neutral results.
