In microwave, melt chocolate wafers with mint candy together for one minute, stir and continue melting in 30 second intervals until smooth (mine took a total of 2 minutes).

In a large mixing bowl, combine cereal with melted chocolate. Fold with a large wooden spoon until all cereal is coated.

In a large, gallon-sized Ziploc bag, add powdered sugar. Spoon in chocolate cereal mixture. Seal bag and shake until powdered sugar is coating all the cereal completely. Pour onto a large piece of wax paper and allow chocolate to set (about 20 minutes). Combine candies with Chex and store in an airtight container. Enjoy!
