Add white almond bark, chocolate chips, and roasted peanuts to a 6-quart crock pot and stir to combine.
Cover and heat on LOW for 1.5-2 hours, stirring every 30 minutes, until the chocolate is completely melted.
Line a counter or baking sheet with wax paper or parchment paper. Use a 1½ tablespoon cookie scoop to drop spoonfuls of the mixture onto the paper.
Allow clusters to cool completely until hardened, about 1-2 hours at room temperature.
Notes
If using regular salted peanuts, put them in a fine mesh strainer and shake off some of the salt.These will keep in an airtight container at room temperature for up to 7 days. If the kitchen is warm, then store them in the refrigerator. They will stay firm and fresh for up to 2 weeks. Or freeze in a single layer and then transfer to a freezer bag. They will keep for up to 3 months.
