In a 6 quart or larger add all of the dry cereal, pretzels and nuts.
In a small mixing bowl, combine together the remaining ingredients and mix well. Pour over cereal in slow cooker and mix well using a rubber spatula.
Cook on HIGH heat UNCOVERED for 90 minutes, stirring the mixture every 15 minutes to prevent the cereal from burning on the bottom.
After 90 minutes, turn slow cooker to LOW and continue cooking for an additional 20 to 30 minutes, stirring every 5 to 10 minutes until the Chex Mix is crispy.
Spread Chex Mix on a parchment paper lined rimmed baking sheet and allow to cool to room temperature.
Store finished Chex Mix in airtight food storage containers for up to 2 weeks.
