The best substitutes for vegetable oil in brownies

Vegetable oil keeps brownies moist and tender by carrying fat through the batter. You can replace it with butter, melted coconut oil, applesauce, Greek yogurt, or mayonnaise—each one works, but they change the texture or flavor slightly. Butter gives you the richest taste. Applesauce makes brownies cake-like and less fudgy. Coconut oil works almost identically to vegetable oil if you use refined (not virgin) coconut oil, which has no coconut flavor.

The swap is straightforward: use the same amount of your replacement as the recipe calls for in oil. A recipe asking for one cup of vegetable oil takes one cup of melted butter, one cup of applesauce, or one cup of Greek yogurt. The bake time and temperature stay the same. What changes is how the brownie feels in your mouth and how it tastes the next day.

Key Takeaways

  • Butter, melted coconut oil, applesauce, Greek yogurt, and mayonnaise all replace vegetable oil in a one-to-one ratio by volume.
  • Butter produces the richest flavor and fudgiest texture, while applesauce creates a cake-like brownie that is less dense.
  • Refined coconut oil mimics vegetable oil most closely and does not add coconut flavor to your brownies.
  • Brownies made with applesauce or yogurt may dry out faster than those made with oil or butter, so store them in an airtight container.

Butter: the richest choice

Melted butter is the most common swap and produces brownies that taste deeper and more indulgent. Use the same volume of melted butter as the recipe calls for in oil. Butter contains water and milk solids that oil does not, so your brownies will be slightly less fudgy and slightly more cake-like, but the difference is small—most people prefer the flavor trade-off.

Brownies made with butter stay fresh for three to four days in an airtight container at room temperature. They also freeze well for up to three months. If your recipe uses both oil and butter, you can replace only the oil with more butter, or use half butter and half another substitute if you want to keep the fudgy texture.

Applesauce: the cake-like alternative

Unsweetened applesauce replaces oil one-to-one and produces brownies that are noticeably lighter and more cake-like. The applesauce adds moisture without the richness of fat, so the crumb becomes airier. This works well if you want brownies that are less heavy or if you are avoiding dairy and eggs are already in your recipe.

Applesauce brownies dry out faster than oil-based ones, so eat them within two days or store them in the freezer. You may also notice a faint apple flavor, though unsweetened applesauce is mild. If your recipe is very sweet already, the applesauce will not add noticeable sweetness, but if you are using a less-sweet brownie recipe, taste the batter before baking and add a tablespoon of sugar if needed.

Coconut oil: the neutral oil swap

Refined coconut oil (not virgin) works almost identically to vegetable oil because it has a similar fat content and neutral flavor. Use it in a one-to-one ratio. Refined coconut oil is processed to remove the coconut taste, so your brownies will not taste like coconut. Virgin or unrefined coconut oil will add a noticeable coconut flavor, which some people enjoy but most do not want in brownies.

Coconut oil is solid at room temperature, so melt it before mixing it into your batter. The texture and moisture of the finished brownie will be nearly identical to one made with vegetable oil. Coconut oil brownies stay fresh for three to four days and freeze well.

Greek yogurt: the protein-rich option

Plain Greek yogurt replaces oil one-to-one by volume and adds protein to your brownies. The result is denser and more cake-like than oil-based brownies, with a slightly tangy undertone that most people do not detect. Greek yogurt works best in recipes that already include eggs, since the eggs help bind the batter.

Use full-fat Greek yogurt for the richest result. Non-fat yogurt will produce drier brownies. Stir the yogurt into your wet ingredients until smooth before mixing in the dry ingredients. Brownies made with yogurt are best eaten within two days and should be stored in an airtight container, as they dry out faster than oil-based brownies.

Mayonnaise: the surprising substitute

Mayonnaise is mostly oil and egg, so it works as a one-to-one replacement for vegetable oil. The result is rich, fudgy, and indistinguishable from a brownie made with oil and eggs—because mayonnaise is essentially those two things emulsified. Use plain mayonnaise, not flavored varieties.

This swap works best if you are comfortable with the ingredient and do not mind the idea of mayonnaise in your dessert. The flavor is not detectable in the finished brownie. Mayonnaise brownies stay fresh for three to four days and freeze well. This is a good option if you have mayonnaise on hand but no oil or butter.

How to choose the right substitute

Pick your substitute based on the texture you want and what you have available. If you want brownies as close as possible to the original recipe, use melted butter or refined coconut oil. If you want a lighter, cake-like brownie, use applesauce. If you want to add protein or avoid dairy, use Greek yogurt. If you want the richest flavor and do not mind a slightly less fudgy texture, use butter.

The bake time and oven temperature do not change. Check your brownies at the time the recipe specifies by inserting a toothpick into the center—it should come out with a few moist crumbs, not completely clean and not wet. Brownies made with applesauce or yogurt may bake a minute or two faster because they contain water, so start checking a minute early.

Frequently Asked Questions

Can I use a mix of substitutes?

Yes. You can use half butter and half applesauce, or half coconut oil and half yogurt. This lets you balance richness with a lighter texture. Use the same total volume as the recipe calls for in oil, divided between your two choices.

Will my brownies taste different with a substitute?

Butter and refined coconut oil taste nearly identical to vegetable oil. Applesauce and yogurt produce a noticeably lighter, more cake-like brownie. Mayonnaise is undetectable. The flavor difference is small—most people notice the texture change more than the taste.

Do I need to adjust the recipe if I use applesauce?

No adjustment is required, but applesauce brownies dry out faster, so store them in an airtight container and eat them within two days. If your recipe is very dry to begin with, applesauce is a good choice because it adds moisture.

What if I do not have any of these substitutes?

Melted butter is the most common pantry item and works in a one-to-one swap. If you have neither oil nor butter, you can use melted chocolate mixed with a small amount of water, though this changes the flavor and requires some trial.

Can I use olive oil instead of vegetable oil?

You can, but olive oil has a strong flavor that will taste noticeable in brownies. Extra-virgin olive oil is not recommended. If you use it, choose a mild or light olive oil and expect a subtle fruity or peppery note in the finished brownie.
