The best butter replacements depend on what you want from the cookie

Butter does three things in a cookie: it adds fat for richness and texture, it creams with sugar to trap air and lighten the dough, and it browns during baking to add flavor. No single replacement does all three equally well. Oil adds fat but won't cream. Applesauce keeps cookies moist but makes them cake-like. Coconut oil browns like butter but tastes different. The right choice depends on whether you care more about texture, flavor, moisture, or how the dough behaves while you mix it.

Start by understanding what you're trading away. Butter is about 80 percent fat and 15 percent water. Most replacements are either all fat (oil, coconut oil) or mostly water (applesauce, yogurt). That difference changes how your dough rises, spreads, and bakes. A cookie made with oil will be greasier and flatter than one made with butter. A cookie made with applesauce will be softer and denser. Neither is wrong—they're just different cookies.

Key Takeaways

  • Oil and coconut oil work best when you want a tender, moist cookie that spreads more than a butter cookie would.
  • Applesauce and mashed banana make cookies denser and cake-like, and you'll need to reduce the amount by about 25 percent to avoid a soggy result.
  • Greek yogurt and sour cream add moisture and tang without making the dough greasy, but they require you to reduce other liquids in the recipe.
  • Nut butters like peanut butter and almond butter work best in recipes that already call for them or in cookies where their flavor fits the other ingredients.
  • Most replacements work best when you use them for only half the butter in a recipe, then use a second replacement for the other half.

Vegetable oil and neutral oils for a tender, spreadable cookie

Vegetable oil, canola oil, and other neutral oils are the most straightforward swap. Use the same amount of oil as you would butter by weight. The cookies will be softer, greasier, and spread more during baking than a butter cookie would. They'll also brown less and taste less rich, because oil doesn't brown the way butter does.

Oil works best in recipes where you don't need the dough to hold its shape—drop cookies like chocolate chip or oatmeal, or cookies that are supposed to be chewy rather than crisp. It's a poor choice for cutout cookies or anything that needs to stay in place while baking. The dough also won't cream with sugar the way butter does, so you'll lose some of the light, airy texture that comes from trapping air bubbles. Mix the oil with sugar by hand or with an electric mixer for a minute or two to get as much air in as you can.

Coconut oil for browning and richness without dairy

Coconut oil browns during baking the way butter does, so it adds more flavor and color than neutral oil. Use the same amount as you would butter. The cookies will taste like coconut unless you use refined coconut oil, which has the coconut flavor removed. Even refined coconut oil changes the texture slightly—the cookies will be a bit more tender and spread a little more than a butter cookie.

Coconut oil is solid at room temperature, so you can cream it with sugar just like butter. That means you'll get some of the light, airy texture back. It works well in chocolate chip cookies, sugar cookies, and anything where a subtle coconut flavor won't clash with the other ingredients. Avoid it in recipes where the coconut taste would be out of place, like lemon cookies or anything with a savory bent.

Applesauce and mashed banana for moisture and density

Applesauce and mashed banana are mostly water, so they make cookies denser and more cake-like. Use about 75 percent of the amount of butter the recipe calls for—if the recipe says one cup of butter, use three-quarters cup of applesauce. The cookies will be moister and softer, and they'll brown less. They also won't spread as much during baking.

These replacements work best in recipes where you want a chewy or cake-like texture anyway—brownies, molasses cookies, or anything with warm spices. They're a poor choice if you want a crisp or snappy cookie. The dough won't cream with sugar, so mix it well but don't expect the same rise. Applesauce is neutral in flavor, so it works in any recipe. Mashed banana adds banana flavor, which works in some cookies but not others.

Greek yogurt and sour cream for tang and moisture

Greek yogurt and sour cream add moisture and a slight tang without making the dough greasy. Use about 75 percent of the amount of butter the recipe calls for, and reduce the other liquids in the recipe (milk, water, or eggs) by about one-quarter. The cookies will be softer and more tender than a butter cookie, with a subtle sour flavor that works well in chocolate, vanilla, or spiced cookies.

These replacements work best when you're already using some liquid in the dough—a recipe that calls for milk or buttermilk, or one with a lot of eggs. In a dry dough, the extra moisture can make the cookies spread too much or bake unevenly. The dough won't cream with sugar the way butter does, so you won't get as much rise. Mix well to incorporate air, and don't overwork the dough or the cookies will be tough.

Nut butters for flavor and richness

Peanut butter, almond butter, and other nut butters are mostly fat, so they work similarly to oil—the cookies will be tender and spread more than a butter cookie. Use the same amount as you would butter. The nut flavor will be strong, so these replacements work best in recipes where that flavor fits: peanut butter cookies, chocolate-peanut butter cookies, or anything with nuts already in it.

Nut butters are thicker than oil, so they'll cream slightly with sugar, giving you a bit more rise than you'd get with neutral oil. They brown a little during baking, adding some depth of flavor. They work well in drop cookies and chewy cookies, but not in cutout cookies or anything that needs to hold its shape. Make sure you're using natural nut butter without added sugar, or reduce the sugar in the recipe to avoid over-sweetening.

Mixing two replacements for better results

The best approach for most recipes is to use half of one replacement and half of another. For example, use half coconut oil and half applesauce, or half oil and half Greek yogurt. This gives you some of the browning and richness of one replacement and some of the moisture and texture of another. The result is closer to a butter cookie than using a single replacement alone.

Start by replacing half the butter with one ingredient and half with another, then bake a test batch. If the cookies spread too much, add a tablespoon of flour to the next batch. If they're too dry, add a tablespoon of milk or water. Most recipes are flexible enough to handle small adjustments without failing. Keep notes on what worked so you can repeat it next time.

How to adjust your recipe for the replacement you choose

The most important adjustment is to the amount of liquid in the dough. If you're using applesauce, mashed banana, yogurt, or sour cream, reduce the milk, water, or other liquid by about one-quarter. If you're using oil or coconut oil, you don't need to adjust the liquid. If you're using nut butter, reduce the liquid slightly because nut butter is thicker than oil.

The second adjustment is to mixing time. Butter creams with sugar to trap air, which makes cookies rise and become lighter. Oil doesn't cream, so you won't get as much rise. Mix the oil and sugar together for a minute or two to incorporate as much air as you can, but don't expect the same result. If you're using coconut oil, which is solid at room temperature, you can cream it like butter and get more rise.

The third adjustment is to baking time. Cookies made with oil or applesauce may bake faster because they're wetter. Check them a minute or two earlier than the recipe says. Cookies made with nut butter may bake at the same speed as butter cookies. Start checking at the time the recipe says, then adjust based on what you see.

Frequently Asked Questions

Can I use margarine instead of butter in cookies?

Yes, margarine works similarly to butter because it's made to mimic butter's behavior. Use the same amount. The cookies will taste slightly different—margarine has a different flavor profile than butter—and some margarines contain water, which can make the dough wetter. Stick margarine works better than tub margarine because it has less water. The results will be close to a butter cookie but not identical.

What if I use all oil and the cookies spread too much?

Add a tablespoon of flour to the next batch, or chill the dough for 30 minutes before baking. Oil makes dough spread more because it doesn't trap air the way butter does. Chilling slows the spread by keeping the dough firm longer while the oven heats. If you're using a lot of oil, you might also reduce the amount slightly—try using 90 percent of the oil the recipe calls for and see if that helps.

Do I need to use the exact same amount of replacement as butter?

No. Oil and coconut oil work best at the same weight as butter. Applesauce and mashed banana work best at about 75 percent of the butter amount. Yogurt and sour cream work best at about 75 percent. Nut butters work best at the same amount as butter. Start with these ratios, then adjust based on how the dough looks and how the cookies bake. Keep notes so you can repeat what works.

Will cookies made with oil stay fresh as long as butter cookies?

Oil-based cookies often stay fresh longer because oil doesn't go rancid as quickly as butter. Store them in an airtight container at room temperature for up to a week. Cookies made with applesauce or yogurt may dry out faster because they have more water, so eat them within three to four days. Cookies made with nut butter stay fresh about as long as butter cookies.

Can I use avocado or mayo as a butter replacement?

Avocado works similarly to oil—use the same amount and expect softer, greasier cookies. Mayo is mostly oil with some egg, so it works similarly to oil as well. Both add moisture and fat without browning. Avocado has a subtle flavor that works in some cookies but not others. Mayo adds a savory note that works only in very specific recipes. Start with a small batch to see if the flavor works for you.
