In the video, a person is seen using a brush to apply a white substance onto a tray of cookies. The cookies are cut into triangular shapes and are arranged neatly on the tray. The person is using a black brush with a yellow handle to apply the white substance, which appears to be icing or glaze. The brush strokes are even and precise, ensuring that the icing is applied evenly across the surface of each cookie. The tray is placed on a countertop, and the background is blurred, but it appears to be a kitchen setting. The person's hand is visible, and they are wearing a ring on their finger. The video is shot in close-up, focusing on the tray of cookies and the person's hand as they apply the icing.
