Yes, you can bake with olive oil — and once you understand how it behaves, you may reach for it before butter for certain recipes. It adds richness, moisture, and a depth of flavor that neutral oils simply cannot replicate. That said, it is not a universal swap, and that is completely okay. In our house, we use butter for American cookies and pancakes, and olive oil for just about everything else. It has worked out really well.
Butter to Olive Oil Conversion Chart
Replacing butter with olive oil is not a 1:1 conversion. Because olive oil is 100% fat while butter contains roughly 18% water and milk solids, you generally need slightly less of it. The standard rule is a 3:4 ratio — for every 4 parts butter, use 3 parts olive oil.
| Butter Amount | Olive Oil Substitute |
|---|---|
| 1 Teaspoon | ¾ Teaspoon |
| 1 Tablespoon | 2¼ Teaspoons |
| ¼ Cup | 3 Tablespoons |
| ½ Cup | ⅓ Cup |
| 1 Cup | ¾ Cup |
How Olive Oil Behaves in the Oven
To understand olive oil as a baking fat, start with the numbers. Olive oil is 100% fat and liquid at room temperature — though if your kitchen runs cold, a high-quality EVOO may turn cloudy or semi-solid, which is completely normal. Learn why olive oil gets cloudy here. Butter is 80% fat and 18% water, solid until heated. That difference in water content is what drives almost every baking outcome.
Moisture retention: Because olive oil contains no water, it keeps baked goods moist far longer than butter does. A banana bread made with EVOO will still be soft and tender on day three. The same loaf made with butter tends to dry out by day two as the water content evaporates out of the crumb.
Density over lift: When butter bakes, its water content turns to steam, which creates rise and helps produce those lovely light, flaky layers everyone loves. Olive oil skips that step entirely — there is no steam, no lift from water evaporation. The result is a denser, fudgier, more compact crumb. That is exactly what you want in a brownie or a moist chocolate loaf, and exactly what you do not want in a croissant or a fluffy layer cake.
Flavor depth: Olive oil is not neutral. It pulls flavors deeper into the batter and amplifies what is already there — intensifying dark chocolate, brightening citrus, adding a subtle herbaceous complexity that refined vegetable oil simply cannot match. A lemon loaf or olive oil cake made with a good EVOO tastes like it was made with intention. The oil is part of the flavor, not just the fat.
The Producer's Take: Do Not Fear the Pepper
Many home bakers worry that a robust EVOO will taste too "olivey" in a cake. In Calabria, we lean into it. For chocolate bakes, use a peppery, full-flavored oil like our Lina. The polyphenols in the oil interact with the bitterness of the cocoa to produce a flavor that is far more complex than anything you'll get with butter or a refined neutral oil.
What Works and What Does Not
Best Results With Olive Oil
- Brownies: Olive oil brownies become almost fudge-like the day after baking — denser, richer, and more shelf-stable than butter brownies. We have an Olive Oil Brownies recipe in The Olive Oil Enthusiast, and a full breakdown on the blog: Can You Use Olive Oil in Brownies?
- Waffles: This is one of our favorite things in the world — waffles made with olive oil come out incredibly crunchy on the outside and soft on the inside, and the herbaceous, nutty flavor profiles of the oil come through perfectly. Served hot with syrup or jam, it is genuinely exceptional.
- Olive Oil Cake: A classic Italian bake where the oil is the star, not a background note. Citrus, pear, and peach pair beautifully. We have an olive oil cake recipe in The Olive Oil Enthusiast, and King Arthur Baking has a well-tested Chocolate Olive Oil Cake worth trying too.
- Quick Breads: Banana, zucchini, pumpkin, and lemon loaf all benefit enormously from olive oil's moisture. The moistest lemon loaf bread you will ever make uses olive oil, not butter.
- Focaccia and Savory Breads: Olive oil is the traditional fat here, and there is no substitute. Pizza dough made with olive oil rises beautifully — the oil does not inhibit yeast the way butter can. Find our focaccia recipe here.
- Dense Cookies and Muffins: Olive oil works well in any cookie or muffin that is meant to be chewy and moist rather than crispy and airy.
Stick With Butter For
- Pancakes: Do not do it. Olive oil pancakes are flat and dense, and will not rise the way a great pancake should. The water in butter turns to steam in the pan, and that steam is what creates the lift. Without it, you end up sacrificing quite a few pancakes before accepting that butter is the right fat here. Trust us on this one.
- Chocolate Chip Cookies: Classic American chocolate chip cookies need butter. The water content in butter has to "escape" during baking to create that perfect slightly crispy, slightly chewy texture. Olive oil produces a good cookie, but it will be noticeably different — more dense and soft, less golden.
- Laminated Pastries: Croissants and puff pastry rely on layers of cold, solid butter to create their characteristic flakiness. As the butter melts in the oven, it releases steam that separates each layer. Liquid fat cannot replicate this structure.
- Fluffy Layer Cakes and Meringues: These require creaming butter and sugar together to beat air into the fat. That trapped air is what makes them light. Liquid fats do not aerate the same way.
Is Baking With Olive Oil Healthier?
From a nutritional standpoint, yes. Extra virgin olive oil is high in monounsaturated fat and rich in polyphenols and antioxidants, unlike butter which is predominantly saturated fat. A large systematic review published in the Cochrane Database of Systematic Reviews found that reducing saturated fat intake and replacing it with unsaturated fats leads to a meaningful reduction in cardiovascular risk. Swapping butter for EVOO in your baking is one practical way to make that shift without sacrificing flavor. For more on the health profile of EVOO, see our post on polyphenol-rich olive oil.
Frequently Asked Questions
Can I substitute olive oil for vegetable oil in baking?
Yes, in a 1:1 ratio. Unlike refined seed oils, extra virgin olive oil is unrefined and retains its natural antioxidants, which remain largely stable in the oven.
Will olive oil make my baked goods taste like olive oil?
It depends on the oil and the recipe. Our Turi is the most suitable for baking as it tends to be a medium oil that adds a subtle complexity that works beautifully in chocolate, citrus, and nut-based recipes. It will not taste like a salad dressing.
Can I use olive oil in box cake mix?
Yes. Swap the vegetable oil called for in the mix with the same amount of olive oil. The result is a slightly denser, more moist cake with better flavor than the neutral oil version.
Does olive oil affect how long baked goods stay fresh?
It actually extends freshness. Because olive oil does not contain water, baked goods made with it retain moisture longer than butter-based versions. An olive oil brownie or quick bread will stay tender a day or two longer.
What is the best olive oil for baking?
For delicate recipes — light cakes, muffins, waffles — use a mild EVOO. For chocolate bakes, citrus cakes, and focaccia, a more robust oil adds real flavor. Either way, always use extra virgin. See our full cooking guide for more on choosing the right olive oil.
