The original recipe for this mix is from Quick Cooking Magazine. I'm posting the original recipe, I will note where I made changes to it.
Sweet Snack Mix
3 cups Honey Grahams cereal
1 cup miniature pretzels
1 cup salted peanuts ( I use cashews)
1 cup pecan halves
1 package (10 to 12 ounces) vanilla or white chips ( I use Wilton Brand white chocolate melting discs because they set up much faster)
In a large bowl, combine the cereal, pretzels and nuts; set aside. In a microwave safe bowl, heat the discs 30 seconds at a time, stirring after each interval until melted and smooth. Pour over cereal mixture. Stir to coat evenly. Spread mixture on wax paper until cooled and set. Break into pieces. If using the Wilton discs, you will need to work quickly as they set up fast.
