What You Need: 1 cupcake; chocolate frosting; pastry bag and #233 metal tip; white or off-white frosting; pastry bag and small, round metal tip (#2 is good); 2 white M&Ms; 2 black M&Ms; black writing icing in a tube (or, use a black food-safe marker.)
How to Make It: Frost cupcake with a thin layer of chocolate frosting. Put chocolate icing in pastry bag affixed with #233 metal tip. Use tip to make long strands that overlap for a furry effect. Squeeze a dot of black writing icing onto white M&Ms for eyes and place on cupcake. Add black M&M nose. Use white icing and round tip to “draw” a mouth and/or teeth.
