Heat the candy melts as directed on the back of the bag as most brand vary. I usually heat mine on defrost mode for 1:30 and repeat this three times then stir well.
Place parchment paper on a small baking sheet. Pour some white candy melts and brush into a stripe with a back of a spoon. Do this leaving room in between. Pour out black candy melts and brush into a stripe with the back of a spoon in between the white stripes.
Shake out green sprinkles over the entire bark. Let dry for about 30 minutes. Once hard break apart into medium pieces for serving.
