KANSAS CITY — Ready-to-eat cereal manufacturers are innovating by the spoonful.

General Mills is adding two new options to the cereal aisle. New Fruity Lucky Charms feature fruit-flavored corn cereal pieces mixed with classic Lucky Charms marshmallows, while new Cinnamon Toast Crunch Churros cereal features bite-size churros dusted with cinnamon and sugar.

The Kellogg Co. has extended its Special K brand with the debut of Special K Protein Honey Almond Ancient Grains cereal, featuring 15 grams of protein per serving. The Honey Almond Ancient Grains ready-to-eat cereal includes flakes made from a mix of whole grains, including the ancient grains sorghum and black rice alongside wheat and rice. The cereal is finished with honey and crunchy almonds.

“When Special K hit shelves in the 1950s, it was the first cereal to feature key vitamins and nutrients, including protein,” said Christie Crouch, director of marketing for Special K. “Today, we continue to look for ways to innovate that stay true to that heritage and do more with both nutrition and taste. That’s why our new Protein cereal recipes include a nutrient bundle designed to help you get more from your protein.”

Post Holdings, Inc. has partnered with Hostess Brands, Inc. to introduce two new cereal offerings: Post Hostess Donettes cereal and Post Hostess Honey Bun cereal. The companies described new Post Hostess Donettes cereal as “the perfect tiny and sweet addition to your breakfast table.” The new cereal is a takeoff of Hostess powdered sugar Donettes. Meanwhile, Post Hostess Honey Bun cereal features the sweet taste of Hostess’s Honey Bun sweet goods.
