Line a large baking sheet with parchment paper.
Layer on the chex cereal, pretzels, cheerios, M&Ms, and marshmallows.
Melt the candy melts, by microwaving on 30 second increments, stirring well between.
Drizzle half of the candy over the mixture, and then toss to coat.
Drizzle half of the remaining, and toss again.
Drizzle the rest of the almond bark, and let the candy set for about an hour.
Before serving, break the candy up into pieces.
