Blend everything in a blender until smooth. Pour mixture into 6 ice cream pop molds (amount may vary based on size of popsicle mold). Place in the freezer and freeze at least 4-6 hours, or until firm and set, (or overnight).
To coat bars in chocolate, microwave chocolate in a small bowl for 30-90 seconds, stirring every 30 seconds, until melted and smooth. Dip frozen peanut butter bars in chocolate and place on a piece of parchment paper (or non-stick foil). Sprinkle crushed peanuts over chocolate while it is still warm and stick bars back in freezer for about 5-10 minutes to allow chocolate to harden, and enjoy!
