To the bowl of your slow cooker, add the Planter's Winter Spiced Mix, the mixed nuts from the Planter's Holiday Collection Tin, rice squares cereal, corn squares cereal, pretzels, and toasted o's cereal.
In a heavy bottomed sauce pan, melt the butter over low heat. Once melted, whisk in the brown sugar, honey, cinnamon, cloves, ginger, nutmeg, salt and cayenne pepper until smooth and combined. Let cook for 2-3 minutes and then remove from heat.
Pour the sauce over the snack mix, and stir thoroughly until the snack mix is evenly coated.
Cook on low for 3 hours, stirring every hour, so that the mix does not burn.
Once cooked, pour the snack mix into an even layer onto a large baking sheet. Let dry and cool completely. Serve or store in an airtight container for 2 weeks.
