In the video, a person is seen decorating a chocolate cake with chocolate frosting and sprinkles. The cake is placed on a white surface, and the person uses a spoon to spread the frosting evenly over the cake. After that, they sprinkle pink and white sprinkles on top of the frosting. The cake appears to be a rectangular shape, and the frosting is a glossy, rich brown color. The sprinkles are small and round, adding a pop of color to the cake. The person's hand is visible as they work on the cake, and they seem to be taking care to ensure that the frosting and sprinkles are distributed evenly.
