For best flavor, be sure the cider is well reduced and cooled before adding it to the batter or frosting, as this concentrates the apple taste and prevents curdling; use room-temperature butter, eggs, and milk so the batter emulsifies smoothly and rises evenly; avoid overmixing once the dry ingredients are added to keep the cupcakes tender; if the frosting seems too soft, chill it for 10 to 15 minutes before piping, and store finished cupcakes in an airtight container in the refrigerator for up to three days, letting them come to room temperature before serving.
