Corn Flakes – the best-selling breakfast cereal in the United States. You know them. You love them. But do you know how they were created? Check out this article to learn the surprising story behind the accidental invention of this iconic Kellogg’s product.
As with many notable inventions, Kellogg’s Corn Flakes were created partially by accident. Though the product may not be what the Kellogg brothers were intending to make at the time, their stroke of culinary luck led to the advent of The Kellogg Company and America’s best-selling breakfast cereal.
The Kellogg Brothers’ Battle Creek Sanitarium
Before the Kellogg name was associated with cereal and snacks, Dr. John Harvey Kellogg and his brother Will Kieth (WK) Kellogg were well-known as the operators of the Battle Creek Sanitarium. This so-called “health spa” catered to helping clients tend to a variety of ailments. Treatments included hot and cold water baths, hydro-therapy, electric-current therapy, light therapy, as well as exercise and massage regimens.
The basis of these treatments was inspired by the brothers’ commitment to their faith in the Seventh Day Adventist fundamentalist church. One of the main principles of the religion entailed maintaining the purity of one’s bodily temple. For the Kellogg’s, this meant adhering to a strict “healthy” diet including lots of water and vegetables and discluding substances like alcohol and caffeine.
How Were Corn Flakes Accidentally Discovered?
To support their ideal diets, the brothers started concocting different healthful foods that they and their patients could eat regularly. The goal was to avoid fat, grease, salt, and spices and focus on simple ingredients that were good for the digestive system. So, Dr. John began experimenting by mixing and baking flour, oats, and cornmeal.
As the legend goes, it was during one of these afternoons of cooking that the Kellogg brothers were called away from their kitchen in the midst of mixing a batch of wheat-based cereal and later returned to see that the dough had fermented. When they rolled the dough into thin sheets and baked it, they were positively surprised to find that it turned into perfect crispy and tasty flakes. Over the years, WK continued experimenting with the recipe and eventually found that corn created even more delicious and crunchy flakes than wheat.
How Did Adding Sugar Lead to the Kellogg Cereal Company?
Adding sugar to Corn Flakes led to the formation of The Kellogg Cereal Company due to a dispute between the Kellogg brothers. WK Kellogg began adding sugar to the cereal to enhance palatability, a move strongly opposed by his brother, Dr. John Harvey Kellogg. This conflict escalated into a legal battle, after which WK purchased the rights to the Kellogg name and founded The Kellogg Cereal Company in 1906, capitalizing on the Industrial Revolution's demand for quick breakfast options. The company then introduced innovative marketing strategies, including promotional prizes and the iconic Cornelius Rooster mascot, solidifying Corn Flakes' status as a best-selling cereal despite its departure from its original health food design.

To settle the dispute, WK purchased the rights to use the Kellogg name from his brother after a long legal battle and subsequently founded The Kellogg Cereal Company. The product soon came to boast several “firsts” in the cereal world, including offering the “Funny Jungleland Moving Pictures Booklet” as a prize to encourage sales, and introducing Cornelius (Corny) Rooster as a mascot. Though the Corn Flakes we know today aren’t exactly the health food they were initially designed to be, their success as one of the most iconic and best-selling cereals in the US proves that they were an invention the breakfast world is certainly thankful for.
