In the video, a person is seen decorating a star-shaped cookie with red icing. The person uses a piping bag with a red nozzle to outline the cookie with red icing. The cookie is placed on a piece of parchment paper, and the person's hands are visible as they hold the cookie steady while decorating it. The red icing is applied in a continuous line, starting from the center of the cookie and moving towards the edges, creating a border around the cookie. The person's movements are precise and steady, ensuring that the icing is applied evenly and smoothly. The video is shot in close-up, focusing on the cookie and the person's hands, with the background blurred out.
