Well, I finally decided to give them a try for our trip. Here is the actual recipe, as provided on the Chex website. Only problem was, I did not have vanilla chips and I didn't have a lemon for the zest. So of course, I improvised - a trait I have learned from my Mom who has always used a recipe as a guide! {love you mom}
I substituted a bag of yellow vanilla candy melts for the vanilla chips and lime zest in place of the lemon zest. I used some bottled lemon juice as well as some lemon extract as well. My other alteration was I used the entire box of Rice Chex as it was only slightly more than the 9 cups.
They were yummy! Can't wait to snack on them in the car on our way to California!
