About Oil and Butter Substitution

Substituting oil for butter or butter for oil in recipes requires understanding the fat content and moisture differences between these ingredients.

Key Conversion Facts
  • Butter is about 80% fat and 20% water: When substituting oil (which is 100% fat) for butter, you need less oil than butter.
  • General ratio: Use about 80% of the butter amount when substituting with oil.

  • Some recipes may require additional adjustments beyond just the fat quantity

Frequently Asked Questions (FAQ)

Why is oil multiplied by 1.25 to get butter?

Butter is only about 80% fat and contains water. To match the fat content of oil, you need more butter. The ratio used is: Butter = Oil × 1.25.

Why is butter multiplied by 0.8 to get oil?

Oil is 100% fat. So, when replacing butter with oil, you need less to match the fat content. The formula is: Oil = Butter × 0.8.

Will this affect the taste of my recipe?

Yes, butter has a distinct flavor and helps with structure in baked goods. Oil, while more neutral, often makes things moister. Keep this in mind when converting.
