Butter to Oil Converter

Swap butter for oil in any recipe. Pick how much butter the recipe calls for and the converter works out the exact amount of vegetable or olive oil to use, in cups, grams, ounces, tablespoons, or teaspoons. Handy when:

  • Dairy-free or vegan baking: oil keeps the bake dairy free without needing a vegan butter substitute.
  • You ran out of butter: most kitchens have oil on hand even when the butter dish is empty.
  • You want a moister bake: oil contains no water, so cakes, muffins, and brownies stay soft for longer.
  • Scaling a recipe: punch in any quantity and get the oil amount in the unit you want to measure with.

Convert Butter to Oil

The rule of thumb: replace butter with 3/4 as much oil as the amount of butter. So 1 cup of butter becomes 3/4 cup of oil.

Why Substitute Butter with Oil?

Run out of butter? Cooking dairy-free? Or want a moister bake? Oil is a great substitute. Oil contains no water, so it keeps cakes and muffins softer for longer than butter does.

Which Oil Should I Use?

Go with vegetable oilif you want a neutral result. It won't change the flavour of your bake at all. Olive oil works beautifully in lemon cakes, chocolate bakes, and anything savoury, but it can be a little strong in more delicate recipes.

Frequently Asked Questions

How much oil do I substitute for butter?
Use 3/4 as much oil as the amount of butter. For example, 1 cup of butter becomes 3/4 cup of oil. The ratio works in any unit, so 200 g of butter becomes 150 g of oil. Use the converter above to calculate the exact amount for any quantity. Open butter converter
Can I use olive oil instead of vegetable oil?
Yes. Both vegetable oil and olive oil work as butter substitutes using the same 3/4 ratio. Vegetable oil has a neutral flavour, making it ideal for most baking. Olive oil adds a mild, slightly fruity flavour that suits savoury bakes, lemon cakes, and chocolate bakes. Open olive oil converter
Does melted butter measure the same as oil?
No. Melted butter still contains water and milk solids, so swapping it for oil at a 1:1 ratio leaves a recipe with too much fat and not enough liquid. Use the 3/4 oil ratio when substituting for either solid or melted butter; it accounts for the water content butter brings to the bake. Open butter converter
Can I use coconut oil instead of butter?
Yes. Melted (liquid) coconut oil behaves like vegetable oil, so use the same 3/4 ratio. Solid coconut oil behaves more like butter and can be swapped at 1:1 in cookies and pastry where you want a firmer crumb. Refined coconut oil is flavour-neutral; virgin coconut oil adds a coconut note to the bake.
