In the video, a person is seen decorating a chocolate cake with white icing. The cake is placed on a white plate, and the person is using a piping bag to apply the icing in a circular motion around the cake. The cake appears to be a small, round chocolate cake, and the icing is being applied in a smooth, even layer. The person's hands are visible as they hold the piping bag and move it around the cake, creating a decorative pattern. The background is not clearly visible, but it seems to be a kitchen or a baking area.
