Cakes like this carrot cake or banana bread are different than most cakes in that they call for oil, rather than butter. While the oil doesn't contribute much flavor, especially if you use vegetable oil, it does allow you to serve the cakes cold without them hardening, as they would if they were made with butter. Grate the carrot on the finest holes of a box grater that won't turn it to mush, or use the finest grater attachment on your food processor.
