place slow cooker liner or parchment paper into slow cooker (I strongly recommend using one of these for this recipe)
add listed amount of all 4 cereals and cranberries
2 cups Cinnamon Chex Cereal, 2 cups Corn Chex Cereal, 2 cups Honey Nut Chex Cereal, 1 cup dried cranberries, 1 cup graham squares cereal
stir to mix
in a separate bowl, melt butter ( I use a microwave)
½ cup butter
add brown sugar, pumpkin pie spice and vanilla to butter and stir
¼ cup brown sugar, 1½ teaspoon pure vanilla extract, 1 tablespoon pumpkin pie spice
pour butter mixture over cereal mix and stir well to fully coat.
cook uncovered on HIGH for 2 hours. Stir mixture every 15 - 20 minutes. This is an important step - with out it, snack mix will burn on the bottom.
after 2 hours, remove ceramic pot from slow cooker and allow mixture to cool before serving. If you used a liner or parchment paper, you can remove your mixture from your slow cooker to cool faster. Careully use the sides of the liner or parchment paper as handles to lift the mixture out of the hot slow cooker.
Remove a few cups worth of mixture and hide it somewhere for yourself because the rest will go fast!
