In the video, a person is seen using a piping bag to apply yellow frosting onto a cupcake. The frosting is applied in a circular motion, starting from the outer edge and moving towards the center of the cupcake. The person then uses a spatula to smooth out the frosting, creating a neat and even layer on top of the cupcake. The cupcake is placed on a white plate, and there are other cupcakes visible in the background. The frosting appears to be of a creamy consistency, and the cupcake has a golden brown color, indicating it is freshly baked. The video provides a close-up view of the frosting process, allowing viewers to see the technique used to achieve a professional-looking finish.
