Any vegetable fat can be substituted with another. You can go from butter to Extra Virgin Olive Oil and back. All vegetable fats have the same amount of calories which is 9.3 cal/ml.

How to Substitute

Butter is made of milk solids and water, so we can’t do an even substitution. The simple guideline in amount conversion is that we use 25% less olive oil than the required butter in the recipe. For example 1 teaspoon butter will be ¾ of the teaspoon if olive oil is used.  If we try to substitute in an even amount, the final outcome will be greasy and “oily”.

If the recipe requires some kind of vegetable oil, we can substitute evenly.

So now you know that you can easily leave butter back in the fridge and use olive oil for:
