The video shows a close-up of a person's hand using a piping bag to apply white frosting onto a chocolate cake. The cake is round and has a crumbly texture. The frosting is applied in a circular motion, creating a pattern of white peaks on the top of the cake. The piping bag is held at an angle, and the frosting is applied in a consistent, swirling motion. The background is a plain white surface, and the lighting is bright, highlighting the contrast between the white frosting and the dark chocolate cake.
