This crock pot party mix recipe couldn't be easier to make. And, unlike the new chex party mix recipes, which call for microwaving the butter and seasonings, then just tossing with the party mixture, this one gets the same toasty flavor you get by making chex party mix in the oven. Make this chex party mix recipe in the slow cooker a few hours before ready to serve it. Just stir the party mix every 45 minutes or so, to ensure that all of the pieces are evenly coated.
