This classic chiffon cake recipe is perfect for any occasion. Made with the Thermomix, it is light, fluffy, and has a delicate texture. The cake is made with a combination of cake flour, sugar, baking powder, salt, vegetable oil, egg yolks, water, and vanilla extract. The egg whites are whipped separately and then folded into the batter to give it its signature airy texture. This cake is perfect for serving with fresh fruit or whipped cream.
