Dip Nutter Butters into the candy melts. Place on wax or parchment paper to dry (don't just put them directly on a cookie sheet, they will stick).
While cookies are still a little bit wet, place two candy eyes about 2/3 of the way down for the eyes (we want to leave room for the ears). Allow to dry for 20-30 minutes.
Once the cookies are dry, use the pink frosting to pipe loops for ears and a little heart below the candy eyes for the nose.
Use the black frosting to pipe whiskers and a mouth. If using a piping tip, I use a Wilton #1 or #2.
