I made this cake and a dozen coordinating cupcakes for a baby shower with a rubber ducky theme. It was a 6" round yellow cake with lemon curd filling (YUM), frosted with vanilla buttercream. The ducky design on the top is made of fondant. The ducky cupcakes are also yellow cake with lemon curd inside. The head is a donut hole and the tail is a marshmallow (cut on the diagonal.) After constructing the "skeleton" of each duck, I dipped them in melted yellow frosting and then added fondant eyes and beaks. How cute are they????
