In a large bowl, measure out cereal and set aside.
In a large ziploc bag, add powdered sugar and 2 teaspoon of pumpkin pie spice. Shake it around a little to incorporate.
In another bowl, melt candy melts (or white chocolate) in the microwave at 30 second intervals until melted and stir in 1 teaspoon of pumpkin pie spice. Pour mixture over cereal and gently mix very well until all cereal is completely coated with the chocolate.
Dump cereal mixture into the bag of spiced sugar, seal it up and shake vigorously until all of the cereal is thoroughly coated with the sugar mixture. You can go ahead and dump it in a bowl and enjoy right away, but I like to pour mine into a strainer and give it a little shake to remove the excess sugar. Add marshmallow creme pumpkins and serve.
