*For a gluten-free mix, choose corn and rice Chex and use gluten-free pretzels.
Pro tip: I sometimes sprinkle in a few more peanuts (for more saltiness) and red and green M&Ms (for additional holiday color) to the cooled mix. And remember that you can customize the mix to any occasion by using the appropriate holiday M&Ms.
A few more things… I start out with the lesser amount of Chex (in my case 3 cups each Corn and Rice Chex) and then usually end up adding the final 2 cups once I am sure I have plenty of chocolate to coat the entire mixture. It is fine, of course, to have some pieces that are less coated that others. Helpful hint: When measuring the ingredients, be sure to use level cups in order to maintain the right ratio of dry ingredients to melted chocolate. Of course, you may absolutely adjust the amount of individual ingredients to taste. Just have a little extra white chocolate on hand if you plan to increase or add without subtracting elsewhere.
