Light as air, wonderfully moist, and delicately rich, this classic chiffon cake is one of the most elegant cakes you can bake from scratch. It combines the lofty softness of angel food cake with the tender richness of a traditional butter cake, thanks to whipped egg whites and oil working together in the batter. Whether you're serving it plain with fresh berries and whipped cream or using it as the base for an impressive layer cake, this timeless recipe delivers a tall, fluffy cake with an incredibly soft crumb every single time.
