The video shows a person's hands as they decorate a chocolate cake. The cake is placed on a white plate, and the person uses a piping bag to add chocolate frosting in a circular pattern around the edge of the cake. They then use a knife to spread the frosting evenly over the top of the cake. The cake is round and appears to be a rich, dark brown color. The person's hands are steady as they work, and the frosting is applied with precision. The video ends with the person smoothing out the frosting on the top of the cake.
