For each jar, you will need to mix a topping. Mix cake mix and pumpkin pie spice, and add to the top of one jar. Drizzle with 2 tbsp melted butter and sprinkle on 1 tbsp nuts. Repeat with all four jars. Add lids to each jar and screw on tightly. Place jars in the top rack of your dishwasher. Be sure to turn on any high temp functions, and turn off any air dry functions. Let the dishwasher run a complete cycle then remove the jars. THEY WILL BE HOT! You can open the jars and serve the pumpkin pie directly from the jar. We love this recipe topped with a scoop of vanilla ice cream or some whipped cream. Enjoy!
