The video shows a cake being decorated on a rotating stand. The cake is initially frosted with white icing on top, and then the sides are also frosted with white icing. The cake is then covered with more icing to create a smooth and even finish. The cake is rotated to ensure that all sides are evenly coated. The video is shot against a purple background, and the cake is placed on a white plate. The cake appears to be a round cake with multiple layers.
