I decorated this tiny cake this morning as an example for the class that I am doing tonight for the Mia Maids (14-15 year old girls at church). It took me 5 minutes and is the easiest way to get an impressive finish without worrying about smoothing out the frosting.
I thought it would be fun for them to not just have a free-for-all with frosting, but actually learn a technique that they could easily replicate.
Here is a quick video on how to ruffle a cake for anyone interested. You need a petal tip (103/104).
