The video shows a close-up of a cake with red and white icing being swirled together to create a marble effect. The cake is on a plate, and a knife is being used to spread the icing. The red icing is being swirled into the white icing, creating a visually appealing pattern. The knife is moved in a circular motion, and the red icing is spread evenly throughout the white icing. The cake appears to be freshly made, and the icing is glossy and smooth. The video is shot in a well-lit room, and the focus is on the cake and the knife.
