Related to Butter
Margarine
Margarine is built to behave like butter, with a similar fat-to-water ratio and a near-identical weight (235 g vs 227 g per cup). Expect a slightly softer crumb and a less buttery flavour. See our Margarine converter.
Shortening
Shortening is 100% fat against butter's 80%, so add water to make up the missing moisture. Result is flakier in pie crust and sturdier in cookies, but you lose butter's flavour. See our Shortening converter.
Ghee
Ghee is butter with the water and milk solids cooked off, so it swaps in 1:1 by volume and adds a nutty depth. It is slightly lighter per cup (218 g vs 227 g) and has a much higher smoke point, making it the better choice for frying and high-heat roasting. See our Ghee converter.
Vegetable Oil
Vegetable oil is a pourable liquid fat that keeps bakes moist for longer than butter, though it skips butter's flavour and the air you beat in when creaming. Use roughly 7/8 cup of oil per cup of butter, and our butter to oil converter works out the exact amount. See our Vegetable Oil converter.
Olive Oil
Olive oil swaps in for melted butter in many cakes and breads, adding moisture and a savoury depth. It is lighter by cup than butter (216 g vs 227 g), so weigh when substituting and reduce the quantity slightly to avoid a greasy crumb. See our Olive Oil converter.
Peanut Butter
Peanut butter swaps in for butter in cookies and no-bake bars, adding a nutty flavour and dense texture. It is heavier than butter (268 g vs 227 g per cup), so weigh when substituting and expect a richer, less flaky result. See our Peanut Butter converter.
