                Place white chocolate chips in a microwave-safe bowl. Heat in 25-second increments at 50% power, stirring well between each interval. Continue until most chips are melted, then stir until completely smooth. Be careful not to overheat. Once melted, stir in 1½ teaspoons of cinnamon.

                Transfer the coated cereal back to a bowl or spread it on a baking sheet lined with parchment paper. Allow it to cool for about 15 minutes before serving so the chocolate can set.
