The video shows a close-up of a person's hand, covered in a clear plastic glove, as they fill a cupcake liner with a yellow batter. The person uses a spoon to scoop the batter and then presses it into the liner, ensuring it is evenly distributed. The cupcake liner is placed in a tray with several other cupcake liners, some of which already have batter in them. The tray is made of a shiny gold material, and the cupcake liners are white with a scalloped edge. The batter appears to be smooth and has a creamy consistency.
