The video shows a close-up of a person using a piping bag to apply white frosting onto the top of a carrot cake muffin. The muffin is placed on a cooling rack, and there are several other muffins visible in the background. The frosting is applied in a circular motion, creating a swirl on top of the muffin. The muffin has a golden brown color and is studded with chunks of carrot and nuts. The piping bag is made of metal and has a nozzle at the end.
