The video shows a close-up of a person decorating chocolate cupcakes with green frosting. The person is using a piping bag with a star-shaped nozzle to create a swirl on top of each cupcake. The cupcakes are placed on a white plate, and the frosting is bright green in color. The person's hand is steady as they apply the frosting in a circular motion, creating a visually appealing design on each cupcake.
