Prepare your cupcakes according to the box directions. Most boxed cake mixes should include the directions for making cupcakes.

Allow cupcakes to cool completely before decorating.

Put some of the icing into a ziplock bag and seal shut. Snip a tiny corner off the bag to form a makeshift icing piping bag.

Ice the top of the cupcake - only cover about half of the surface area as the marshmallows will push it down the sides.

Put in your sheep head (instructions above in post).

Stick the marshmallows into the icing.

Let harden enough for the marshmallows to set before eating.
