The video shows a person's hand using a brush to apply icing on cookies. The cookies are cut into triangular shapes and are arranged neatly on a baking tray. The icing is white and appears to be of a thick consistency. The person's hand moves methodically from one cookie to the next, ensuring that the icing is evenly distributed. The cookies have a golden-brown color, suggesting that they are freshly baked. The background is blurred, but it appears to be a kitchen setting.
