Place the almond bark in the crock pot. Top with the chocolate chips and the peanuts. Cook on low for 1 hour.
Stir every 15-20 minutes to ensure that chocolate does not burn on the bottom of the crock pot.
Once all ingredients are melted, stir thoroughly to combine.
Use a spoon or a cookie scoop to scoop clusters onto a cookie sheet lined with wax paper or parchment paper. Put in the refrigerator or all them to sit at room temperature until the chocolate has completely set (usually 1-2 hours).
Store the clusters in an airtight container or ziplock bag in the refrigerator. Enjoy!
