Why measuring vegetable oil by cup goes wrong
Neutral vegetable oils — canola, sunflower, refined safflower, soybean — all weigh within 2 grams of each other at about 218 grams per cup. They behave the same in baked goods: more tender crumb than butter (no water content to evaporate), less flavor, slightly heavier mouthfeel.
Practical tips for working with vegetable oil
Oil-based cakes stay moist longer than butter-based cakes because oil stays liquid at room temperature while butter solidifies. That's a meaningful win for a birthday cake that needs to look good two days after baking. Carrot cake, banana bread, and many chocolate cakes lean on oil for exactly this reason.
Note from this ingredient's record: Neutral oils (canola, sunflower, refined sunflower) all hover within 2 g per cup. Cold-pressed oils that smell strongly of seed are not neutral and will flavor a cake.
