Substitute for Unsalted Butter: Best Swaps by Recipe

A substitute for unsalted butter depends on how the recipe uses it: unsalted margarine is the closest direct swap, while neutral oil works best when the butter is melted. Use the conversions below to replace 1 cup (227 g) of butter, and choose a swap that suits the texture your recipe needs.

Ingredients

Unsalted butter in the recipe: 1 cup (227 g), as the amount you are replacing
Unsalted stick margarine: 1 cup (227 g), for a close all-purpose, one-to-one substitute
Neutral oil, such as canola or avocado oil: ¾ cup (180 ml), for recipes that use melted butter
Refined coconut oil: 1 cup (218 g), for a solid-fat substitute; choose refined for a milder flavor
Ghee: 1 cup (215 g), for cooking or baking where a buttery flavor is welcome
Unsweetened applesauce: ½ cup (120 ml), to replace half the butter in some moist quick breads or muffins
Fine salt: ¼ teaspoon (1.5 g) per ½ cup (113 g) salted butter, only if using salted butter instead of unsalted

Instructions

Check how the butter is used. Read the method before choosing a swap. Butter that is melted into a batter is easier to replace than butter creamed with sugar, rubbed into pastry, or folded into a flaky dough. The recipe’s method is the best clue to whether it needs liquid fat, cool solid fat, or butter’s particular flavor.
Choose one replacement for each cup. For the closest one-to-one substitution, use 1 cup (227 g) unsalted stick margarine. If the recipe calls for melted butter, use ¾ cup (180 ml) neutral oil instead. If it needs solid fat, use 1 cup (218 g) refined coconut oil, softened but not liquid. These are alternatives, not ingredients to combine.
Adjust the salt only if needed. If salted butter is your only option, use the same amount by volume and reduce the recipe’s added salt by about ¼ teaspoon (1.5 g) for each ½ cup (113 g) of salted butter. Salt levels vary among brands, so check the label and be conservative when the recipe already has salty ingredients.
Mix it in the way the recipe directs. Melt oil gently if the method calls for melted butter, but do not try to cream liquid oil with sugar. For solid margarine or coconut oil, follow the recipe’s temperature and mixing instructions. A substitute can change the dough or batter’s feel, so avoid adding extra flour or liquid unless it is clearly necessary.
Make a small trial when texture is critical. If you are baking an important cake, cookie, or pastry, test a half batch or a few cookies first. Note that the result may spread, brown, or taste different. This quick conversion guide takes about 2 minutes to use; any baking time belongs to the original recipe.

Tips

Use stick margarine, not a tub spread, for baking. Stick margarine is usually formulated to behave more like butter. Soft tub spreads often contain more water and less fat, so a one-to-one swap can make cookies spread, cakes bake up differently, or pastry turn soft. Read the package rather than assuming all margarine is interchangeable.
Do not use oil for every job. Oil can be a practical swap in muffins, quick breads, and some cakes that call for melted butter. It cannot trap air when creamed with sugar, and it does not form the same flaky layers as cold butter in biscuits or pie crust. For those methods, use a solid substitute or choose a recipe developed for oil.
Keep temperature in mind. Coconut oil melts at a relatively low temperature. If it is too warm when you cream it, it may not hold air; if it is too cold, it can be hard to mix. Use it softened and pliable, not hot or fully liquid, when a recipe calls for creaming.
Expect some flavor and color differences. Neutral oil is less buttery, while coconut oil may contribute a coconut note unless it is refined. Many butter substitutes also brown differently from butter. Start checking baked goods near the earliest time given in the original recipe, and rely on doneness cues rather than color alone.

Serving Suggestions

This conversion is a starting point for adapting the dish already on your menu, rather than a finished dish to serve by itself. Use neutral oil in a simple snack cake, banana bread, or muffin batter when the original method adds melted butter to the wet ingredients. The baked result is usually tender, but it will have less of butter’s rich aroma. A flavored glaze, fruit, or a light dusting of sugar can suit those bakes without masking them.

For stovetop cooking, a measured amount of oil can replace butter for sautéing vegetables, cooking eggs, or greasing a pan. Add only enough to coat the pan at first; recipes sometimes use butter for flavor as well as to prevent sticking. If you want a buttery taste, a small amount of ghee or a dairy-free butter alternative can be added near the end of cooking. Taste before adding salt, especially if the other ingredients are seasoned.

Variations

For a dairy-free swap: Use a dairy-free stick baking block in the same amount as the unsalted butter, provided the label says it is suitable for baking. Products differ in salt and water content, so the result may not be identical. A neutral oil can work in recipes designed for melted fat, but it is not a dependable replacement for creamed butter or pastry butter.

For a buttery flavor: Ghee has a concentrated buttery taste and can replace butter in many sautéed dishes and some bakes. Because it is clarified, it contains less water than regular butter, so delicate baking recipes may come out drier or more crumbly. For a closer baking match, stick margarine is generally more predictable.

For a lighter-textured quick bread: Replace half the butter with unsweetened applesauce, keeping the other half as butter, margarine, or oil. This can make the crumb softer and more moist, but it also reduces richness and may make the center seem dense or gummy if used in excess. It is best reserved for muffins and quick breads, not cookies, pie crusts, or recipes that depend on creaming.

For a recipe that uses salted butter: You can use unsalted butter in equal quantity and add salt to the recipe, but follow the recipe’s listed salt amount rather than adding an arbitrary extra pinch. This page focuses on replacing unsalted butter; the reverse swap is mostly a matter of accounting for salt, and brands vary in how salty their butter tastes.

Storage and Reheating

This is a conversion guide, so there is no prepared butter substitute to store. Keep margarine, coconut oil, and ghee according to their package directions, using a clean utensil and closing the container after each use. Do not mix oil with water or another liquid in advance and leave the mixture on the counter: it will not form a stable butter-like emulsion and can separate.

If you use a substitute in a cooked dish, refrigerate leftovers within 2 hours. Most cooked leftovers keep for 3–4 days in a covered container in the refrigerator. Reheat portions until steaming hot; for dishes that require a temperature check, USDA FSIS advises reheating leftovers to 165°F (74°C). For baked goods, follow the original recipe’s storage advice, since fillings and toppings can change how long they keep. Freeze suitable baked goods in airtight packaging if you need to store them longer, and thaw them in the refrigerator or at room temperature as appropriate.

Frequently Asked Questions

What is the best substitute for unsalted butter in baking?
Unsalted stick margarine is usually the closest one-to-one option for general baking because it is solid and often formulated for similar use. For recipes that call for melted butter, ¾ cup (180 ml) neutral oil can replace 1 cup (227 g) butter, though the flavor and texture will change. Check whether the recipe creams, melts, or chills the butter before choosing.

Can I replace unsalted butter with oil at a one-to-one ratio?
Usually not. Oil is pure fat, while butter contains water and milk solids, and it stays liquid rather than becoming firm when cool. A practical starting point for recipes using melted butter is ¾ cup (180 ml) oil for each cup (227 g) butter. That conversion is not a universal fix for cookies, frosting, laminated pastry, or recipes that rely on creaming.

Can I use salted butter instead?
Yes. Replace unsalted butter with the same amount of salted butter, then reduce the recipe’s added salt by roughly ¼ teaspoon (1.5 g) for each ½ cup (113 g) butter. Since salt levels differ by product and recipe, use the package label and taste savory mixtures before adding more salt. In baking, make the adjustment before mixing.

Is margarine the same as butter for cookies?
Not exactly, but unsalted stick margarine is often a workable one-to-one swap. Cookies may spread differently, brown less, or have a less buttery taste. Tub spreads are less reliable because their water content and softness can differ substantially. For a recipe that depends on chilling the dough or creaming butter and sugar, use a solid baking product and follow the original chilling instructions.

Can applesauce replace butter in any recipe?
No. Applesauce is a moist fruit purée, not a fat with the same structure as butter. It can replace part of the butter in some muffins and quick breads, but it may make cookies, pastry, and cakes that depend on creaming too soft or dense. Start by replacing only half the butter, and expect a different flavor and crumb.

What should I use if I need a dairy-free substitute?
Choose a dairy-free baking stick or block and check that it is intended for baking; some soft spreads contain more water and are better suited to topping than to dough. For recipes using melted butter, neutral oil may also work. Coconut oil is another dairy-free solid fat, though it can add flavor and behaves differently from butter as it warms.
