Place white sugar and cinnamon in a gallon-sized ziptop bag. Shake to combine and set aside.
1/2 cup White Sugar, 2-3 Tablespoons Cinnamon
Measure Chex cereal into a large mixing bowl. Set aside.
4 cups Chex cereal
Place white chocolate chips in a small microwave-safe bowl and melt for 25 seconds. Stir and reheat as needed. (You can also add a bit of coconut oil or shortening to make the mixture more melty.)
1 cup White Chocolate Chips or White Chocolate Wafers
Pour the melted white chocolate chips over the Chex cereal and stir to coat.
Scoop the Chex cereal into the bag with the cinnamon sugar mixture, then seal and shake to coat the cereal completely.
Pour the cinnamon sugar-coated cereal onto a cookie sheet and allow the white chocolate to set completely, approximately 30 minutes, before storing or serving.
