Line a cookie sheet with parchment or wax paper. Set aside.

In a large bowl, mix together the Chex cereal, Cheerios, and pretzels. 

Add the white chocolate melts or almond bark to a heat proof bowl. Set the bowl over a pot of barely simmering water and heat until the candy has completely melted and is smooth.

Remove the melted candy from the heat and pour over the cereal and pretzel mixture.  Using a rubber spatula, toss until all the dry ingredients are evenly coated in the melts. Pour the mixture out onto the paper lined cookie sheet. Use your spatula to spread out the cereal into an even layer.

Sprinkle on the M&Ms and sprinkles in an even layer, while the candy coating is still wet.

Allow the White Trash to sit at room temperature until candy coating has set, about 20-30 minutes. You can also pop this in the fridge for 5-10 minutes for a quicker set.

Once hardened, break it up into chunks and enjoy immediately or transfer the chunks into desired packaging to give as gifts!

White trash can be stored at room temperature in an airtight container for up to a week.
