Begin by adding the white almond bark, semi-sweet chocolate chips, and broken pieces of German chocolate to the crockpot. Layer the salted peanuts, unsalted peanuts, and pecan halves on top of the chocolate.
Set the crockpot to LOW and secure the lid. Allow the mixture to cook gently for 1.5 to 2 hours, stirring every 30 minutes to ensure the chocolate melts evenly and the ingredients combine smoothly.
Once the chocolate is fully melted and the nut mixture is well coated, use a spoon or small cookie scoop to drop dollops of the candy mixture onto baking sheets lined with parchment paper.
While the chocolate is still soft, garnish the tops of each cluster with M&Ms, pressing them lightly to ensure they adhere.
Let the candy cool and set completely at room temperature for about 1 to 2 hours. If you’re short on time, place the baking sheets in the refrigerator to speed up the setting process.
Once the clusters are firm, transfer them to an airtight container. These festive treats are perfect for enjoying at home or gifting in decorative tins to spread holiday cheer.
