The video shows a close-up of a cake being decorated. The cake is pink and has colorful sprinkles on the sides. A piping bag with pink frosting is used to create a swirl pattern on top of the cake. The frosting is applied in a circular motion, starting from the center and moving outwards. The piping bag is held steady as the frosting is piped, creating a smooth and even swirl pattern. The video ends with a close-up of the finished frosting swirl on top of the cake.
