Prep your parchment paper before starting- you can either lay it out on the counter or cover 3 large baking sheets and set aside.
Combine pretzels, cheerios, corn chex, peanuts, and m&m’s into a VERY large bowl. If you don't have a big enough bowl, use two and put equal amounts of each ingredient in both bowls.
In a microwave-safe bowl, microwave chips and oil on medium-high for 1 minute. Stir, and then continue to microwave in 10-second intervals (mixing in between each) until completely melted and smooth. Be careful not to burn the chocolate.
Quickly pour the white chocolate over cereal mixture and immediatly mix to coat everything with a rubber spatula or clean hands.
Once coated, spread the chex mix out in an even layer on the prepared parchment paper and let it cool completely. Break apart and store in an airtight container.
Change the theme for different holidays- use green & red m&ms for Christmas, red white and blue for 4th of July. You can even add 3-4 tbsp of colored sprinkles to make it extra festive.
Use the biggest bowl you can find- sometimes I have to split this up into 2 bowls if I don't have one big enough.
Use your hands- I find that mixing the white chocolate into the chex mix works best if you use your hands vs. a spatula. Gives you a nice even coat, so don't be afraid to get your hands a little dirty!
Use parchment or wax paper- this is the easiest to use if you don't want your white chocolate to cool and stick to whatever you put it on.
Cut this recipe in half- this makes A LOT of chex mix, so if you don't want a ton leftover just cut the recipe in half (although you won't regret leftover, I promise).
Storing and freezing:
Store in an airtight container or ziplock bags. I think this is best stored in the FREEZER, it stays fresh and lasts up to 4 weeks… if you keep it around for more than a day that is.
