The calculation
How much oil replaces 1/4 cup butter?
Butter is roughly 80% butterfat and 16% to 17% water, whereas vegetable and canola oils are 100% pure fat. When swapping butter for oil, applying a 1:1 volume swap adds 20% more fat and removes moisture.
Moisture compensation: At 1/4 cup butter, only 9 ml (under 2 teaspoons) of water is lost. No recipe liquid adjustments are necessary in pancakes, muffins, or sauces.
