The video shows a person using a knife to spread blue frosting on a group of cupcakes. The cupcakes are placed on a white surface, and there is a single chocolate cupcake in the foreground. The person's hand is visible as they spread the frosting in a circular motion, covering the top of each cupcake. The frosting appears to be of a thick consistency, and the person is careful to ensure that it is evenly distributed. The blue frosting contrasts with the white surface and the chocolate cupcake, making the cupcakes look visually appealing.
