Place the peanuts into the bottom of the slow cooker.
Cover the peanuts with the peanut butter chips.
Add the semi sweet and milk chocolate chips.
Layer the white chocolate bark or wafers on the top.
Place the lid on the crockpot, and cook on low for 1 hour.
Remove the lid, stir the mixture well and place the lid back on to cook on low for another 30 minutes.
Stir the mixture again, and use a tablespoon to drop clusters of the mixture on pieces of parchment paper.
Allow the candy clusters to harden and set for several hours.
Serve immediately or store in an airtight container. Candies can also be frozen for future use.
