Line a large baking sheet with parchment paper.
In a large mixing bowl, combine the Rice Chex cereal, plain Cheerios, mini pretzels, M&M’s, and peanuts.
Stir gently to distribute the ingredients evenly.
Break the white almond bark into small pieces.
Place the almond bark pieces in a medium saucepan over low heat.
Stir continuously until the almond bark is fully melted and smooth.
Remove the melted almond bark from the heat.
Pour the melted almond bark over the cereal, pretzel, candy, and peanut mixture.
Stir gently until all ingredients are evenly coated.
Transfer the coated mixture to the prepared baking sheet.
Spread the mixture into an even layer.
Allow the mixture to cool completely until the almond bark is fully set.
Once firm, break the mixture into pieces or clusters.
Serve immediately or store in an airtight container.
