What Is a Substitute for Butter?

What's the best butter substitute?

Margarine is the closest 1-to-1 butter substitute because it was designed specifically to replace butter. Use 1 cup of margarine for 1 cup of butter. The behavior in baking is nearly identical, though the flavor is slightly different.

For dairy-free needs, vegan butter (Earth Balance, Miyoko's, or similar) is the closest 1-to-1 substitute. The texture and behavior in baking match butter so closely that most recipes work without any adjustment. For non-vegan substitutes, shortening (1-to-1) works in baking but lacks flavor; combine with butter extract (1/2 teaspoon per cup) for closer flavor.

Can you use oil instead of butter?

For baking: yes, with adjustments. Use 3/4 cup of liquid oil (vegetable, canola, or melted coconut oil) for every 1 cup of butter. The result is denser and slightly more moist than butter-based baking. For cookies that need to spread, oil works fine; for cookies that need to hold shape, butter or shortening is better.

Olive oil works as a butter substitute in some recipes (Mediterranean-style cakes, olive oil cake) where the flavor fits. For most American baking, neutral oils work better because they don't add their own flavor. Coconut oil (1-to-1 in solid form for creaming, melted 1-to-1 for liquid butter applications) is a popular vegan option.

What about applesauce or other fat-reducing substitutes?

Applesauce replaces butter in some baking applications to reduce fat. Use 3/4 cup of unsweetened applesauce per 1 cup of butter, but only replace half the butter (about 1/2 cup applesauce plus 1/2 cup butter) for best results. Full replacement makes baked goods denser and less rich.

Mashed banana, pumpkin puree, and Greek yogurt work similarly. Each substitutes for some of the butter while preserving moisture. For frostings, sauces, and pastry where butter is structural rather than just adding moisture, these substitutes don't work; they're best for cakes, muffins, and quick breads.

When does the butter substitute fail?

For croissants, puff pastry, and laminated doughs, butter is essential because the cold solid butter creates the layers. No substitute fully replicates this. Vegan butter comes closest; shortening works but produces less flavorful pastry.

For sauteing where butter's browning and flavor matter, oils work but the flavor changes noticeably. For French sauces (beurre blanc, hollandaise), butter is the defining ingredient and substitutes don't work. For everyday baking and cooking, most butter substitutes work fine and the flavor differences are subtle. For browned butter applications, only real butter browns properly; substitutes don't have the milk solids needed for the browning reaction.
