To get it to look so perfect like that takes a special tool called a tip (or sometimes icer tubes). The tip goes on the edge of special frosting bag and as you squeeze the forsting out through it different tips force the frosting into different shapes.
Frostings you can buy in the store will work for this, but you could also google any old frosting recipe you'd like and use it with a tip to get that look. [ Razhie's advice column | Ask Razhie A Question ]
