The video shows a close-up of a person using a piping bag to apply white frosting to a cupcake. The cupcake is placed in a paper cup and has a chocolate piece on top. The person is using a green piping bag to apply the frosting in a circular motion, starting from the center and moving outwards. The frosting is applied in a smooth, even layer, covering the top of the cupcake. The person's hand is steady, and the frosting is applied with precision. The video ends before the frosting is completely applied.
