Add the chocolate bark, chocolate chips, sliced almonds, condensed milk, and coconut to the crockpot.
Set the slow cooker to low and let everything melt together for about an hour, stirring halfway through.
Once the chocolate is fully melted and smooth, stir again to make sure every bit of coconut and almond is evenly coated.
Line a baking sheet with muffin cup liners or parchment paper.
Using a small cookie scoop or tablespoon, drop generous portions of the candy mixture into each liner.
While the chocolate is still soft, top each cluster with a whole almond for that signature Almond Joy look.
Transfer the tray to the refrigerator and let the candies set for about an hour, or until firm.
