For best results, crush the cereal just before using so it stays crisp, and avoid overmixing the batter after adding the flour to keep the cupcakes tender. Room-temperature ingredients help the batter emulsify and rise evenly, so pull butter, eggs, and milk out of the fridge 30 minutes ahead. If you need to make them in advance, bake the cupcakes a day early, store them covered at room temperature, and frost shortly before serving to prevent the cereal garnish from getting soggy. You can adjust the cinnamon level in both the batter and frosting to taste, and if your frosting becomes too soft while piping, chill it for 10 to 15 minutes to firm it back up.
