I got some ideas from this site and came up with my own version for a friend's baby shower. The cake is the Mermaid Bakery butter cake recipe and the frosting is extra special buttercream, the towel, blanket, accessories and bubbles are gumpaste - my first time working with it and found it easier to work with than fondant. Duckies are storebought white chocolate that I found in the Easter candy. Really enjoyed making this cake, and everyone loved it!
