How to Substitute Olive Oil for Butter
Use olive oil in place of butter for moist batters while accounting for flavor and structure changes.

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.
Use this amount
3/4 tbsp
for 1 tbsp Butter
Approx. 1 g
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.
Best Uses
Recipe Context
- Best for olive oil cakes, loaf cakes, muffins, quick breads, and brownies.
- Avoid for butter cookies, pie dough, buttercream, and laminated pastry.
Troubleshooting
- Choose mild olive oil unless the recipe welcomes peppery flavor.
- Expect a softer texture and less creamed-butter lift.

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.
