The video shows a person decorating a cake with walnuts. The cake has multiple layers and is covered with white frosting. The person is seen sprinkling walnuts on top of the cake, starting from the center and moving towards the edges. The walnuts are chopped into small pieces and are light brown in color. The person's hand is visible as they sprinkle the walnuts, and they are wearing a ring on their finger. The cake is placed on a white plate, and the background is blurred, but it appears to be a kitchen setting.
