National Cereal Day takes place on March 07, 2023. If you belong to the roundabout 50 percent Americans, who don't start their day with a bowl of cereal, this is the perfect day to do so anyway. Otherwise you could have cereal for a midnight snack. Cereal emerged as a healthy breakfast choice at the end of the 19th century. To celebrate Cereal Day with friends, you can also bake a cake which contains cereal. With about 5,000 different types of cereal you can use your imagination to create new recipes or just enjoy a different type every morning.
