The video shows a person decorating a Christmas tree-shaped cupcake. The cupcake is covered in green frosting and decorated with red and white candy pieces. The person is seen adding a white frosting base at the bottom of the cupcake and then placing the green frosting on top to form the shape of a Christmas tree. They then add red and white candy pieces to the tree to mimic ornaments. The video ends with the person holding the finished cupcake in their hand.
