Best Substitutes for Unsalted Butter
Unsalted butter provides 80% fat, 16% water, and 4% milk solids. These three components create texture, moisture, and flavor in cooking. The fat carries flavors and creates tender crumbs. The water turns to steam for lift in baking. The milk solids brown to create nutty complexity. Your substitute needs to match these roles based on what you're making. Creaming recipes need solid fat at 65F. Melted butter recipes accept liquid fats. Pastry needs the exact water content for flaky layers.
Best Overall Substitute
Salted butter at a 1:1 ratio, reducing any added salt in the recipe by 1/4 teaspoon per stick. It matches unsalted butter exactly except for 90mg of sodium per tablespoon. The texture, fat content, and baking behavior are identical. Just adjust the salt.
All Substitutes
Salted butter
1:1 by weightSalted butter contains the same 80% fat and 16% water as unsalted, plus 90mg sodium per tablespoon. The salt preserves the butter and adds flavor. In baking, reduce recipe salt by 1/4 teaspoon per stick (8 tablespoons) of salted butter used. For pastry, the salt slightly strengthens gluten development, creating marginally tougher crusts. In savory cooking, salted butter actually improves flavor depth.
Ghee
1:1 by weightGhee is butter with water and milk solids removed, leaving 99% pure butterfat. It has a 485F smoke point versus butter's 350F, making it superior for high-heat cooking. The nutty flavor from browning the milk solids during ghee production adds complexity. In baking, the lack of water means less steam, creating denser textures. Cookies spread more. Pie crusts are less flaky.
Coconut oil (refined)
1:1 by weight, chilled to butter consistencyRefined coconut oil contains 82% saturated fat, closest to butter's texture when solid. It melts at 76F, similar to butter's 90-95F range. The lack of water (0% versus butter's 16%) means adding 1 tablespoon milk per 1/2 cup coconut oil improves texture in cakes. Refined coconut oil has no coconut flavor. Virgin coconut oil adds subtle tropical notes that work in chocolate or vanilla recipes.
Vegan butter
1:1 by weightQuality vegan butters blend oils (palm, coconut, canola) with water to mimic butter's 80% fat content. Brands like Miyoko's or Earth Balance perform nearly identically to dairy butter in baking. They cream well, creating proper cookie spread and cake rise. The flavor is neutral to slightly nutty. Some brands contain more water, making pastries slightly less crisp. Check labels for palm oil if avoiding it.
Clarified butter
1:1 by weightClarified butter removes milk solids and water, leaving pure butterfat like ghee but without browning. It has a 450F smoke point and clean butter flavor. The lack of milk solids means no browning reactions, and the missing water (0% versus 16%) affects texture in baking. Cakes are denser. Cookies spread more. It excels in sauces because it won't break or separate like whole butter.
Olive oil (light)
3/4 cup oil per 1 cup butterLight olive oil has neutral flavor and 100% fat versus butter's 80%. Use 25% less volume because of higher fat density. It creates moister, denser textures since it lacks butter's water content. Cakes have a tender crumb but don't rise as much. Cookies spread significantly. The liquid state means it won't cream, so use only in melt-and-mix recipes or where melted butter is called for.
Lard
1:1 by weightLard contains 100% fat with no water, making it ideal for flaky pastries. It has a higher melting point (97-104F) than butter, creating superior pie crusts that hold their shape. The lack of milk solids means no browning flavor. Leaf lard (from around kidneys) has the mildest taste. Back lard has stronger pork flavor. Modern processed lard is often hydrogenated and inferior to fresh rendered lard.
Neutral oil (canola, vegetable)
3/4 cup oil per 1 cup butterNeutral oils provide 100% fat with no water or milk solids. Use 25% less volume than butter. They create moist, tender textures but can't replicate butter's flavor or creaming ability. Canola oil has a 400F smoke point, good for cooking. Vegetable oil (usually soybean) has a more neutral flavor. Both work only in melt-and-mix recipes where liquid fat is acceptable.
Applesauce
1/2 cup applesauce per 1 cup butterApplesauce provides moisture and binding with virtually no fat (0.2% versus butter's 80%). Use half the volume of butter called for. It creates dense, moist textures but lacks the richness and mouthfeel of fat. Baked goods are more cake-like and less tender. The natural pectin provides some structure. Unsweetened applesauce works best to control sugar levels. Combined with a small amount of oil (2 tablespoons per 1/2 cup applesauce), results improve significantly.
How to Adjust Your Recipe
Check your recipe method first. Creaming recipes beat butter with sugar to trap air, requiring solid fat at 65-68F. Liquid substitutes won't work. Melt-and-mix recipes accept any liquid fat substitute directly. For pastry, butter's 16% water content is critical for steam and flakiness.
When using oils, reduce oven temperature by 25F because oils conduct heat faster than butter. Add 1-2 tablespoons milk when using pure fats (ghee, coconut oil) to replace butter's water content in cakes. Salt adjustments matter with salted butter: reduce recipe salt by 1/4 teaspoon per stick used.
When Not to Substitute
Laminated pastries (croissants, puff pastry, Danish) need butter specifically. The water creates steam between layers, and the fat content must be exact for proper layering. Brown butter recipes can't be substituted because the Maillard reaction between milk solids and heat creates the entire flavor profile.
Buttercream frosting needs butter's specific melting point and creaming ability. Pound cakes rely on butter's exact fat-to-water ratio for their dense, fine texture. European-style breads like brioche need butter's plasticity for proper gluten development.
Frequently Asked Questions
Can I substitute margarine for unsalted butter in baking?
Yes, at 1:1 ratio, but results vary by brand. Stick margarine (80% fat) works better than tub versions (60-70% fat). Cookies spread more due to higher water content. Cakes may be slightly gummy. The flavor difference is noticeable, especially in butter-forward recipes like sugar cookies or pound cake.
How much coconut oil replaces 1 stick of unsalted butter?
Use 8 tablespoons (1/2 cup) coconut oil for 1 stick (8 tablespoons) butter at 1:1 ratio. Chill coconut oil to butter consistency for creaming recipes. Add 2 teaspoons milk to replace butter's water content in cakes. Refined coconut oil has no coconut flavor.
What's the difference between ghee and clarified butter as substitutes?
Both are pure butterfat with no water or milk solids, working at 1:1 ratios. Ghee has a nutty flavor from browning milk solids during production. Clarified butter tastes like pure butter. Both have high smoke points (450-485F) versus butter's 350F, making them superior for high-heat cooking.
Can I use olive oil instead of butter in chocolate cake?
Yes, use 3/4 cup light olive oil per 1 cup butter. The chocolate masks olive oil's flavor. The cake will be moister and denser with a tender crumb. Extra virgin olive oil adds slight fruity notes that pair well with chocolate. Avoid in vanilla or delicate flavored cakes.
Why do my cookies spread too much when I substitute oil for butter?
Oils are 100% fat versus butter's 80% fat and 16% water. The extra fat and lack of water structure causes spreading. Chill cookie dough 2 hours before baking. Use 3/4 the amount of oil, or add 2 tablespoons flour per 1/2 cup oil substituted to absorb excess fat.
