Related Butter Ingredients
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 what 1 US cup of vegetable oil is in ounces.
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 what 1 US cup of olive oil is in ounces.
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 what 1 US cup of peanut butter is in ounces.
Margarine is a plant-oil spread designed to behave like butter, with a similar fat-to-water ratio and a near-identical weight (235 g vs 227 g per cup). Swap 1:1 by volume in cakes, cookies, and pastry; expect a slightly softer crumb and a less buttery flavour. See what 1 US cup of margarine is in ounces.
Shortening is 100% fat, so it is richer than butter (which is around 80% fat) and lighter per cup at 205 g vs 227 g. Swap by weight in cookies and pie crust for a flakier, sturdier result; expect to lose butter's flavour and add 2 to 3 tablespoons of water per cup to compensate for the missing moisture. See what 1 US cup of shortening is in ounces.
Ghee is butter with the water and milk solids cooked off, close in weight (218 g vs 227 g per cup) with a nuttier flavour and a higher smoke point. Swap 1:1 by volume; ghee browns faster. See our Ghee converter.
