Bake one recipe of your favorite cupcake flavor. While they're baking, make one recipe of your favorite white buttercream.
Divide frosting in half. Reserve first half to remain white.
Use black food coloring to tint the other half grey. Take a smaller portion (about 1/4 of the grey frosting) and add additional food coloring to make black frosting, or use premade black from the grocery store. We won't tell!
Apply thin layer of grey to each cupcake.
Using white frosting and #8 tip, pipe a U shape in the lower 2/3 of the cupcake. Add additional frosting to the bottom portion of the U to represent the elongated snout.
Using the grey frosting, use the #233 grey tip to cover any remaining grey with shaggy fur. Switch to the #352 leaf tip to make the ears.
Using the black frosting and #3 tip, make small black circles for eyes and nose, then draw in mouth.
