In the video, a person is seen decorating a cake with blue frosting. The cake is shaped like a monkey and is placed on a white plate. The person uses a piping bag to apply the frosting, starting from the top of the cake and moving downwards. The frosting is applied in a circular motion, creating a textured effect on the cake. The person's hand is visible in the frame, holding the piping bag and applying the frosting with precision. The blue frosting contrasts nicely with the white plate, making the cake stand out. The video is shot in a well-lit room, and the focus is solely on the cake and the decorating process.
