Preheat oven to 350. Layer cooking spray on the bottom of a baking sheet. You can use foil but works fine without it also, however, spray first either way.
Next, Lay cereal flat across greased pan. Spray a layer of cooking spray on top of all the cereal. Sprinkle 1 tablespoon of sugar and 1 tablespoon of cinnamon across top of cereal. Bake for 10-15 mins. Flip the cereal over, and repeat this step. (spray, sprinkle, and bake again) for another 10-15 mins or until golden brown. Then, Remove from heat and let cool enough to handle.
Meanwhile, pour remaining sugar, cinnamon, and powdered sugar into a gallon ziplock bag. (If using smaller baggies just cut the ingredient amounts back/in half depending on the size of your baggies.) Scoop cereal into bag(s) and seal them without letting the air out. Now SHAKE SHAKE SHAKE! When your cereal is all coated you can transfer to different baggies or container(s) or let the air out and reseal. Or, Serve and Enjoy!
