Melt the chocolate wafers / candy melts in the microwave until smooth and free of lumps.
Cover a cookie sheet with parchment paper. Pour the melted chocolate onto the parchment paper and spread with a spoon. Allow to dry completely before moving on to the next step.
Melt ½ cup of white vanilla chips on the stove over medium heat. Stirring constantly.
Add red food dye and a small amount of lard to the white vanilla chips. Continue to stir. Keep adding red food dye until your chips reach a dark red color. Once you’ve reached the color of blood, remove the chips from the stove. Add more lard if needed to thin to desired consistency.
Dip a spoon into the melted chips and fling it onto the white bark. Keep doing this until you’ve reached your desired look.
While the candy is still wet, add some bone sprinkles. Press them down slightly to help them stick to the candy.
