In the video, a person is seen decorating a cupcake with white icing. The cupcake is red in color and is placed on a wooden table. The person is using a piping bag to apply the icing, starting from the center and moving towards the edges. The icing is applied in a circular motion, creating a swirl pattern on top of the cupcake. The person's hands are visible in the frame, and they are wearing a striped shirt. The background is blurred, but it appears to be a kitchen setting.
