Spray the inside of your slow cooker with non-stick cooking spray to prevent sticking.
In the slow cooker, add the whole almonds, salted peanuts, and shredded coconut. Stir to combine.
Add both the milk chocolate chips and semi-sweet chocolate chips to the slow cooker. If you want a smoother texture, add the coconut oil. Cover and cook on low for 1-2 hours, stirring occasionally until the chocolate is fully melted.
Once the chocolate is melted, stir the mixture to ensure the nuts and coconut are evenly coated with the chocolate.
Using a spoon, scoop small amounts of the chocolate mixture and drop them onto a baking sheet lined with parchment paper. Form into clusters.
Refrigerate the clusters for 30 minutes to an hour, or until they are set and firm.
Once the clusters are fully chilled, enjoy your homemade Almond Joy Chocolate Clusters! Store any leftovers in an airtight container in the refrigerator for up to one week.
