The best oil replacements for brownies are butter, applesauce, and Greek yogurt

Oil in brownies does two things: it carries fat flavor and keeps the crumb moist. When you replace it, you need something that does both. Butter is the most straightforward swap—use the same amount by weight, melted. Applesauce and Greek yogurt work too, but they change the texture slightly, making brownies denser and fudgier. Each replacement has a real trade-off, and which one you pick depends on what you're trying to achieve and what you have on hand.

The reason oil matters is that it doesn't evaporate during baking the way water does. Butter contains water and milk solids alongside fat, so brownies made with butter can dry out faster than oil-based ones if you overbake them by even a minute. Applesauce and yogurt are mostly water, which means they'll make your brownies set faster and feel heavier. None of these are failures—they're just different brownies.

Key Takeaways

  • Melted butter is a one-to-one replacement for oil by weight and produces brownies closest to the original recipe.
  • Applesauce and Greek yogurt reduce fat content but make brownies denser and require you to watch baking time closely.
  • Coconut oil works as a direct oil-for-oil swap and adds subtle coconut flavor unless you use refined coconut oil.
  • Nut butters add richness but can make brownies grainy if not mixed smoothly, and they work best in recipes that already call for nuts.
  • Avoid water, milk, and egg whites alone—they don't contain enough fat to replace oil's role in the batter.

Butter: The closest match to the original recipe

Butter is the safest choice because it's mostly fat, just like oil. Melt it first, then use it in the same amount the recipe calls for oil. A recipe asking for 1/2 cup oil becomes 1/2 cup melted butter. The brownies will taste richer and have a slightly more cake-like crumb than oil-based brownies, but the difference is subtle enough that most people won't notice.

The catch is that butter contains about 15 to 20 percent water, while oil is pure fat. This means your brownies may brown faster on top and dry out more quickly if you leave them in the oven too long. Check them a minute or two earlier than the recipe suggests. If the top looks set but a toothpick comes out with a few moist crumbs, they're done—don't wait for the toothpick to come out completely clean.

Browned butter (butter cooked until the milk solids turn golden) adds a nutty depth that works especially well in dark chocolate brownies. Let it cool to room temperature before mixing it into your batter, or the heat will scramble any eggs you're using.

Applesauce: Lower fat, denser texture

Unsweetened applesauce replaces oil one-to-one by volume, but it changes what you're baking. Applesauce is mostly water and fiber, so brownies made with it will be denser, fudgier, and less rich. They'll also set faster and stay moist longer because the water content keeps them from drying out. This is actually useful if you like fudgy brownies or if you tend to overbake.

The trade-off is that applesauce brownies can taste slightly less chocolatey because there's less fat to carry the cocoa flavor. You can compensate by using a higher-quality cocoa powder or adding an extra tablespoon of cocoa to the dry ingredients. Applesauce also adds a faint fruity note that most people don't detect in chocolate, but it's there.

Use unsweetened applesauce only. Sweetened versions will make your brownies too sweet and throw off the recipe's balance. If you only have sweetened applesauce, reduce the sugar in the recipe by 2 to 3 tablespoons per 1/2 cup applesauce.

Greek yogurt: Tangy, fudgy results

Plain Greek yogurt works as an oil replacement at a one-to-one ratio and produces brownies that are noticeably fudgier and more tender than oil-based ones. The yogurt's acidity reacts with baking soda (if your recipe uses it) to create lift, and the protein in the yogurt helps set the structure. The result is a brownie that's almost cake-like on the outside but dense and moist inside.

The flavor shift is real: Greek yogurt adds a subtle tang that some people enjoy and others don't notice at all. It pairs well with dark chocolate and espresso powder. Use plain, unsweetened yogurt—flavored varieties will throw off the sweetness balance. Full-fat yogurt produces richer brownies than low-fat, but both work.

Stir the yogurt smooth before mixing it into your wet ingredients. Lumpy yogurt won't distribute evenly, and you'll end up with pockets of dense brownie scattered through the pan.

Coconut oil: Direct swap with a flavor note

Coconut oil is pure fat like vegetable oil, so you can use it in exactly the same amount. The difference is flavor. Unrefined (virgin) coconut oil adds a noticeable coconut taste that works in some brownie recipes and clashes in others. Refined coconut oil has the coconut flavor removed, so it behaves like neutral oil with no taste change.

Coconut oil is solid at room temperature, so you'll need to melt it before mixing. Let it cool slightly before adding it to your batter. If your kitchen is very warm, coconut oil may stay liquid—that's fine, just use it as is. Brownies made with coconut oil have a slightly different crumb structure than those made with vegetable oil, often a bit more tender, but the difference is small.

Refined coconut oil is the better choice if you want no flavor change. Virgin coconut oil is worth trying if you like coconut, but start with a recipe you know well so you can judge whether the flavor works for you.

Nut butters: Rich but requires care

Almond butter, peanut butter, and tahini all contain fat and can replace oil, but they're thicker and more flavorful than oil. Use them at a one-to-one ratio by weight, but thin them with a tablespoon or two of water or milk so they mix smoothly into the batter. Nut butters that aren't fully incorporated will create grainy patches in your brownies.

Peanut butter and almond butter add their own strong flavors, so they work best in recipes that already include nuts or in brownies where you want that flavor to shine. Tahini is more neutral and adds richness without as much flavor. All three will make brownies denser and more fudgy than oil-based versions.

Natural nut butters (the kind with just nuts and salt, no added oils or sugar) work better than heavily processed versions because they mix more smoothly. If your nut butter is very thick, warm it gently before using it.

What doesn't work as an oil replacement

Water, milk, and egg whites alone won't work because they contain little to no fat. Oil's job in brownies isn't just moisture—it's fat that stays in the batter during baking. Water and milk evaporate, leaving you with dry, crumbly brownies. Egg whites add structure but not richness, and brownies made with only egg whites taste flat and cake-like in the worst way.

Mayonnaise is mostly oil and egg, so it technically could work, but the vinegar and other seasonings in it will throw off your recipe's flavor. It's not worth the risk. Avocado is high in fat and could work in theory, but its flavor and color will dominate the chocolate, and it's expensive to waste on an experiment.

Frequently Asked Questions

Can I use a mix of replacements, like half applesauce and half butter?

Yes. Mixing replacements lets you balance texture and flavor. Half applesauce and half butter, for example, gives you some of the fudginess of applesauce with the richness of butter. Start with equal parts and adjust based on how the first batch turns out.

Do I need to change the baking time if I use a replacement?

Usually by only a minute or two. Applesauce and yogurt brownies often bake slightly faster because they're denser. Butter brownies may bake at the same speed or slightly faster. Check at the recipe's suggested time, then every 30 seconds after that until the top is set but the center is still soft.

Will brownies made with applesauce or yogurt stay fresh as long as oil-based ones?

Yes, often longer. The water content in applesauce and yogurt keeps brownies moist for several days. Oil-based brownies can dry out faster. Store both types covered at room temperature for up to four days, or freeze them for up to three months.

What if my recipe calls for melted chocolate and oil together?

Melt the chocolate first, then stir in your replacement. If you're using applesauce or yogurt, let the melted chocolate cool for a minute before stirring them in, or the heat will cook the yogurt and make it grainy. Butter can go in while the chocolate is still warm.

Can I use olive oil instead of vegetable oil?

Extra virgin olive oil will add a strong, fruity flavor that clashes with chocolate. Light or refined olive oil is neutral enough to work, but it's more expensive than vegetable oil and offers no real advantage. Stick with vegetable, canola, or coconut oil for brownies.
