The best butter substitutes depend on what you want the cookie to be
Butter does three things in a cookie: it carries fat (which makes cookies tender), it creams with sugar to trap air (which helps them rise), and it browns during baking (which adds flavor). The substitute you pick depends on which of those jobs matters most for your recipe.
Oil replaces butter's fat content but won't cream with sugar or brown. Applesauce and yogurt add moisture and tenderness but make denser cookies. Coconut oil browns like butter and creams like butter, but changes the flavor. Nut butters add richness and structure. Each one shifts how your cookie turns out—and that's not a flaw, it's a choice.
Key Takeaways
- Oil works 1:1 by volume but produces flatter, greasier cookies because it doesn't trap air the way creamed butter does.
- Coconut oil browns and creams like butter and works at a 1:1 ratio, but adds coconut flavor unless you use refined coconut oil.
- Applesauce and yogurt replace only half the butter by weight and make cookies cake-like and dense because they add water.
- Nut butters (peanut, almond) work at a 1:1 ratio and create chewy, structured cookies with their own strong flavor.
- Mashed banana replaces half the butter by weight and works best in chocolate or spice cookies where its sweetness fits the flavor profile.
Oil: the 1:1 swap that changes texture
Vegetable oil, canola oil, and olive oil all work at a 1:1 ratio—if a recipe calls for 1 cup of butter, use 1 cup of oil. The cookies will spread more, bake faster, and stay softer because oil doesn't trap air the way creamed butter does. They'll also taste greasier and won't brown as deeply.
Oil is best for recipes where you don't cream butter and sugar together at the start—like brownies, which already rely on melted fat. For traditional creamed-butter cookies (snickerdoodles, sugar cookies, chocolate chip), oil will give you a noticeably different result: flatter, more tender, less caramelized. If that's what you want, go ahead. If you want the cookie to taste and feel like the original, pick a different substitute.
Coconut oil: browns and creams like real butter
Coconut oil is the closest structural match to butter. It creams with sugar, browns during baking, and works at a 1:1 ratio. Use it the same way you'd use butter—cream it with sugar, then add eggs and dry ingredients.
The catch is flavor. Unrefined (virgin) coconut oil tastes like coconut, which works in some cookies and clashes in others. Refined coconut oil has almost no coconut taste and is the better choice if you want the cookie to taste like the original recipe. Both types are solid at room temperature, so they behave like butter in your mixer. Refined coconut oil is easier to find in most grocery stores.
Applesauce and yogurt: for denser, moister cookies
Applesauce and plain yogurt replace half the butter by weight, not a full 1:1 swap. If a recipe calls for 1 cup (2 sticks) of butter, use 1 cup of applesauce or yogurt instead. You'll need to reduce other liquids in the recipe slightly because both add water.
These substitutes make cookies cake-like and dense because they add moisture without the fat structure that butter provides. They work well in recipes that already have a cake-like texture (oatmeal cookies, molasses cookies) or where you want a chewier result. They won't brown the way butter does, so the cookies will look paler. Both are nearly flavorless, so they won't change the taste profile the way coconut oil does.
Nut butters: for chewy, structured cookies
Peanut butter, almond butter, and other nut butters work at a 1:1 ratio and create cookies with a chewy texture and built-in structure. They cream with sugar almost as well as butter does, though the cookies will spread slightly more. The flavor is strong and obvious, so use them only in recipes where that flavor makes sense—peanut butter cookies, chocolate-peanut cookies, or almond-flavored recipes.
Nut butters are denser than butter, so cookies made with them will be thicker and chewier rather than tender and crumbly. If you use natural nut butter (the kind with oil on top), stir it well before measuring so the oil is evenly distributed. Creamy nut butter works more smoothly than chunky in most recipes.
Mashed banana: for chocolate and spice cookies
Mashed banana replaces half the butter by weight, the same ratio as applesauce. One ripe banana (about 1/2 cup mashed) replaces 1 cup of butter. The cookies will be denser and moister, and banana's natural sweetness means you may want to reduce the sugar in the recipe slightly.
Banana works best in chocolate cookies, spice cookies, or recipes where a slight fruity note fits the flavor. It doesn't work in vanilla or delicate-flavored cookies where the banana taste will be obvious and out of place. Like applesauce, mashed banana won't brown the way butter does, so expect a paler cookie.
Ghee: butter's clarified cousin
Ghee is butter with the milk solids removed, leaving only the fat. It works at a 1:1 ratio and browns beautifully because the milk solids that cause browning are concentrated. Ghee has a slightly nutty, caramelized flavor that's more pronounced than regular butter, so it changes the taste profile slightly—but most people find the change pleasant in cookies.
Ghee is solid at room temperature and creams with sugar the way butter does. It's more expensive than butter and less common in grocery stores, but if you have it on hand or use it regularly, it's an excellent substitute. The main drawback is availability and cost, not performance.
Frequently Asked Questions
Can I mix two substitutes together?
Yes. Mixing oil with applesauce, or using half coconut oil and half nut butter, lets you balance texture and flavor. Start with half the amount of each and adjust based on how the dough looks. This works especially well when you want some browning (from coconut oil or ghee) plus some moisture (from applesauce or yogurt).
Do I need to change the baking time?
Yes, sometimes. Oil-based cookies bake faster and spread more, so check them a minute or two earlier than the recipe says. Applesauce and yogurt cookies bake at about the same speed as the original. Nut butter cookies may bake slightly faster because they're denser. Start checking at the recipe's minimum time and add a minute if needed.
Why do my cookies spread too much with oil?
Oil doesn't trap air the way creamed butter does, so the dough has less structure. Chill the dough for 30 minutes before baking, use a cookie scoop to keep portions consistent, and space them farther apart on the baking sheet. If spreading is still a problem, switch to coconut oil or nut butter, which have more structure.
Will the cookies taste different?
Yes, unless you use refined coconut oil or ghee. Applesauce adds a subtle fruity note, yogurt adds slight tang, nut butters add their own flavor, and mashed banana adds sweetness and fruit flavor. Oil and refined coconut oil are nearly neutral. If you want the cookie to taste exactly like the original, refined coconut oil or ghee are your closest matches.
Can I use butter-flavored oil or margarine?
Margarine works at a 1:1 ratio and behaves like butter because it's formulated to, but it contains water and emulsifiers that change how cookies bake—they often spread more and brown less evenly. Butter-flavored oil is mostly vegetable oil with flavoring added, so it has the same spreading and browning issues as regular oil. Both are less reliable than the substitutes listed above.
