Converting Between Oil and Butter in Cooking and Baking
Converting between oil and butter is a common need in cooking and baking, especially when you're looking to substitute one for the other based on dietary preferences, availability, or desired texture and flavor in the final dish.
Why Convert Between Oil and Butter?
There are several reasons you might want to convert between these two fats:
- Dietary restrictions: You might be looking to avoid animal products or reduce saturated fats.
- Texture differences: Oil tends to make cakes more moist, while butter provides more structure and flavor.
- Ingredient availability: You may simply not have one ingredient on hand and need to substitute.
- Health considerations: Different types of oils and butter have varying nutritional profiles.
Conversion Basics
The basic conversion rule is:
- Oil to Butter: For 1 cup of oil, use 1.25 cups of butter (or about 2.5 sticks)
- Butter to Oil: For 1 cup of butter, use 0.8 cups of oil (slightly less than 1 cup)
These ratios work because butter contains water and milk solids (about 20% of its volume), while oil is 100% fat.
Impact on Your Recipe
When substituting one for the other, keep these factors in mind:
- Flavor: Butter adds a distinct flavor that oil lacks. If this flavor is important to your recipe, consider using a flavorful oil like coconut oil or adding a pinch of salt.
- Texture: Recipes with butter tend to be more structured and can be flakier (like pastries), while oil creates more moisture and tenderness.
- Creaming: Some recipes rely on creaming butter with sugar to incorporate air. Oil cannot be creamed, so recipes may need to be adjusted.
- Melting point: Butter has a higher melting point than most oils, which affects how baked goods set.
Best Practices for Substitution
For best results when substituting:
- Consider the recipe type - some are more forgiving than others
- For delicate baked goods like pastries, substitution may significantly change the outcome
- In cakes and quick breads, substitutions generally work well
- For cooking (sautéing, frying), substitutions are usually straightforward
- When replacing butter with oil, you may need to reduce other liquids slightly

Frequently Asked Questions
While you can technically substitute oil for butter in most recipes, the results will vary. The substitution works best in recipes where butter is melted, like in brownies or quick breads. For recipes that rely on the solid structure of butter (like pie crusts, croissants, or cookies), the substitution may significantly change the texture and final result. Cakes tend to work well with either fat.
The standard conversion is to use about 80% oil when replacing butter. So if a recipe calls for 1 cup of butter, you would use about 4/5 cup (or 0.8 cups) of oil. This is because butter contains about 20% water and milk solids, while oil is 100% fat.
The best oil to use depends on the recipe:
- Neutral oils (like vegetable, canola, or grapeseed): Best for most baking as they don't add much flavor
- Olive oil: Works well in savory dishes and some rustic baked goods, but has a distinct flavor
- Coconut oil: A good option for recipes where you want solid fat at room temperature
- Avocado oil: Works well for high-heat cooking and has a mild flavor
Yes, there will likely be some flavor differences. Butter contributes a rich, distinct flavor that oil doesn't provide. If you're substituting, consider the flavor profile of your recipe. For butter-forward recipes like shortbread cookies, the difference will be more noticeable than in heavily spiced recipes like carrot cake where other flavors dominate.
Oil tends to make baked goods more moist and tender, while butter provides more structure and can create flakiness in certain recipes. Cakes made with oil often stay moist longer and have a softer crumb, while butter-based cakes might have a more structured crumb but can dry out faster. Cookies made with oil tend to spread more and be softer rather than crisp.
Yes, you can substitute butter for oil in many recipes. Use about 1.25 cups of butter for 1 cup of oil. Melt the butter first and allow it to cool slightly before adding to your recipe. This substitution works well in quick breads, muffins, and some cakes, but may change the texture slightly, often making them less moist but adding richness and flavor.
Generally, the baking time and temperature remain the same when substituting oil for butter. However, oil-based batters might cook slightly faster because they don't contain the water found in butter. It's always a good idea to check for doneness a few minutes before the recipe suggests when making substitutions.
This is one of the trickier substitutions because oil cannot be creamed with sugar the way butter can. When a recipe relies on the creaming method, consider these options: 1) Whisk the sugar and oil vigorously to incorporate some air, 2) Beat the eggs and sugar first to create volume, then add the oil, or 3) Look for an alternative recipe that uses oil as the original fat. The texture of the final product will likely be different than if you had used butter.
