How It Works
Butter can be replaced with various fats and other ingredients depending on dietary needs and desired texture. The conversion ratio differs for each substitute because of varying fat and moisture content.
The basic rule:
- Vegetable/canola oil: use 75% of the butter amount (by volume). Butter is ~80% fat + 20% water/milk solids; oil is 100% fat.
- Coconut oil: use a 1:1 ratio (same amount). Melt it first for liquid recipes, or use solid for creaming.
- Applesauce or Greek yogurt: use 50% of the butter amount for partial substitution, or 100% for full sub with texture changes.
Oil substitutions work best in quick breads, muffins, and cakes. For cookies where butter flavor and texture are critical, coconut oil is the closest substitute. Applesauce and yogurt reduce fat and calories but change texture — items will be denser and more moist.
Tips & Considerations

Frequently Asked Questions
Why use only 75% oil when replacing butter?
Butter is about 80% fat and 20% water and milk solids. Oil is 100% fat. Using the same volume of oil would add too much fat. The 75% ratio keeps the fat content equivalent while accounting for the missing moisture (you may want to add 1 tbsp water per ¼ cup butter replaced).
Can I replace butter with olive oil?
Yes, using the same 75% ratio. Extra-virgin olive oil has a strong flavor that works well in savory baking, some cakes, and Mediterranean recipes. For delicate pastries, use light/mild olive oil or another neutral oil like canola or vegetable.
Will applesauce make my baking taste like apples?
Unsweetened applesauce has a very mild flavor that is mostly undetectable in chocolate, spice, and fruit-flavored baked goods. In vanilla or plain recipes, you might notice a slight fruity undertone. Start by replacing only half the butter with applesauce.
Is coconut oil a healthy butter substitute?
Coconut oil has similar saturated fat content to butter, so it is not necessarily healthier. However, it is dairy-free, making it suitable for vegan baking. It adds a subtle coconut flavor. Refined coconut oil has less coconut taste than virgin.
Can I use these substitutes in cookie recipes?
Oil makes cookies softer and chewier but they spread more. Coconut oil works best for similar texture to butter cookies. Applesauce makes cookies cake-like and less crispy. For best results in cookies, only substitute half the butter.
How do I convert butter sticks to other measurements?
One stick of butter = ½ cup = 8 tablespoons = 113 grams = 4 ounces. A standard US butter package contains 4 sticks (2 cups / 454g / 1 pound). Most stick wrappers have tablespoon markings for easy measuring.
