Pretty Purple Pansy Birthday Cake

This yummy cake is covered with "little purple pansies, touched with yellow gold."  And unlike the pretty pansies growing in the garden, these pansies are 100% edible (made of royal icing).  The moist, rich carrot cake is filled with carrots, pineapple, coconut, cinnamon, allspice, nutmeg, and toasted walnuts.  Tasty cream cheese icing fills and covers this yellow and purple birthday cake.  Deliciousness abounds!
