In the video, a person is seen decorating a cake with purple icing. The cake has a unique shape, resembling a mountain with a flat top and a zigzag pattern on the sides. The person uses a piping bag to apply the icing in a circular motion, starting from the center and moving outwards. The icing is a vibrant purple color, and the person applies it with precision, creating a smooth and even layer. The cake itself appears to be a rich, dark purple color, possibly indicating a flavor such as berry or chocolate. The background is blurred, but it seems to be a kitchen or baking area.
