We had the family in on Saturday for a Corned Beef and Cabbage meal. The kids always look forward to a cake and, of course, love the decorations. This is a 1/4 sheet dark chocolate which I divided into 20 squares. Iced and decorated in buttercreme. I outlined each square with a #32 tip, with a rosette in the center. I overpiped the outline in a swirley motion with a #3 tip, and then sprinkled a few green and white jimmies over the entire cake. Each rosette was toped with a little sugar shamrock. Very easy to cut and the kids get to keep their decorations in tact for "just a little longer".
