i did this for my friends that had their engagement party on St. Patricks Day, and the groom is also irish. his last name is Jones- thats why there is a "J" in the middle of the shamrock. its a 1/4 sheet cake bottom. the shamrock is made from a Wilton deep mini hearts pan with extra batter put into a small loaf pan for the stalk. all icing is buttercream.
