● Cake toppings can be made out of stiff royal icing, and stored well in advance. You can make and store different shapes of colored and rolled fondant. Cupcake decoration can also be done with bows made from icing ribbons.
● Eyeballs can be made out of rolled white fondant. Make circles of blue fondant with a black spot in the center. Stick this to the white ball, and place it on top of the cupcake covered with light green fondant. Cut thin strips of red fondant in the shape of veins, and stick to the eyeball.
● Wedding cupcakes should be decorated, and perfectly placed in a cake stand. The popular decorations for weddings are natural or fondant flowers. You can replace flowers with heart-shaped candies or chocolates. You can simply top the cakes with butter cream icing (same color as of the bride's wedding dress), or make the initials of the bride and the groom.
There is no hard and fast rule regarding decoration of cupcakes for different occasions. You can always mix and match various designs, but the result should appear sensible. It is not sensible to serve a cupcake decorated with the shapes of witches during a baby shower party, whereas a cupcake with floral decoration will fit into almost every occasion.
