Butter to Oil Conversion Calculator

Use 3/4 cup (12 tablespoons) of oil to replace 1 cup of butter. This is because butter is about 80% fat and 20% water and milk solids, while oil is 100% fat. Using less oil compensates for this difference.

Oil works well in quick breads, muffins, cakes, and brownies. However, it won't work for recipes that rely on creaming butter with sugar for air (like butter cookies) or where solid fat creates flaky layers (like pie crust and puff pastry).

For baking, neutral oils like canola or vegetable oil work best. Coconut oil is good for a 1:1 swap in many recipes since it's solid at room temperature like butter. Olive oil adds flavor and works well in savory baking.
