In the video, a person is seen decorating a cupcake with white frosting. The cupcake is placed on a white plate with a scalloped edge. The person uses a piping bag with a star-shaped nozzle to apply the frosting in a circular motion, creating a swirl on top of the cupcake. The cupcake itself appears to be a golden-brown color and is topped with a red jam or jelly. The frosting is applied in a steady and controlled manner, resulting in a visually appealing and evenly distributed swirl. The video focuses solely on the cupcake and the decorating process, with no other objects or background distractions.
