In your slow cooker place the almond bark and peanuts.
Cover and cook on low for 2-3 hours stirring often.
Once the chocolate is melted and smooth turn off the slow cooker and let the chocolate mixture cool until room temperature. You don’t want the chocolate to start to harden up but you don’t want it so warm it melts the M&Ms and marshmallows.
Stir the M&Ms and marshmallows into the chocolate mixture and stir gently until just combined.
Scoop 1 - 1 ½ tablespoon scoops onto parchment paper.
