I changed the recipe slightly. Because I wanted to make a double batch (most will go in the freezer) I didn't have a large enough microwaveable bowl. So, I used my super big stainless steel bowl and baked it in the oven, 250° for 45 minutes, stirring every 15 minutes. This is the way I make the Original Chex Mix recipe, it's from those pre-microwave days :)
Give it a try and let me know what you think!
