Cover two baking sheets with parchment paper or silicone baking mats
In a Ziploc bag crush the peppermints using a hammer or meat mallet
In a very large bowl combine the two Chex cereals, bugles, and pretzels. Use two large spoons and gently mix so as not to break up the pieces too much.
Remove half of the cereal mixture and set aside leaving the remaining half in the very large bowl. You are going to work in two batches.
Melt one package of the CandiQuik according to package instructions.
Have your M&Ms, crushed peppermints and sprinkles ready.
Drizzle about one-fourth of the melted CandiQuick over the cereal. Quickly sprinkle M&Ms, peppermints and candy sprinkles (1 tablespoon at a time) over the cereal. Mix gently using two large spoons.
Repeat this step two to three times pouring the melted CandiQuik and then quickly sprinkling M&Ms, peppermints, and sprinkles, then mixing. Do this until you have used all of one package of CandiQuik and half of the M&Ms, peppermints, and sprinkles.
Dump this batch onto your prepared baking sheet letting it completely cool.
Repeat the above steps for the second batch.
