Combine the sugar and cinnamon in a gallon-sized ziptop bag. Shake to incorporate and set aside.
½ Cup (100 g) Sugar, 2-3 Tablespoons (2 Tablespoons) Cinnamon
Measure Chex cereal into a large mixing bowl.
4 Cups (248 g) Chex cereal
In a small microwave-safe bowl melt the white chocolate chips for 25 seconds in the microwave. Stir and reheat as needed.
1 Cup (180 g) White Chocolate Chips or White Chocolate Wafers
Pour the melted white chocolate chips over the Chex cereal.
Carefully stir to coat the cereal, trying not to crush the cereal.
Scoop the Chex cereal into the bag with the cinnamon sugar mixture, then close and shake to coat the cereal completely.
Pour the cinnamon sugar-coated muddy buddies onto a cookie sheet in a single layer and allow the white chocolate to set completely, approximately 30 minutes, before storing or serving.
