KANSAS CITY — The breakfast food category is booming with innovation, from English muffins to mini muffins to ready-to-eat cereal.

Flowers Foods, Inc. has expanded its Dave’s Killer Bread brand breakfast offerings with the launch of English muffins. The muffins, which are certified U.S.D.A.-organic and Non-GMO Project verified, are available in two varieties: Killer Classic and Rockin’ Grains.

The Killer Classic variety has six grams of protein and eight grams of whole grains per muffin and features five grains: quinoa, spelt, rye, millet and barley.

The Rockin’ Grains variety has 20 grams of whole grains per muffin, which Flowers Foods claims is the most whole grains of any organic English muffin on the market. The muffins feature flax, sunflower, sesame, millet and quinoa.

“Consumers are eating breakfast all day … not just in the morning,” said Cristina Watson, brand manager for Dave’s Killer Bread. “They want the convenience of breakfast foods combined with clean ingredients for snacking, second breakfast, lunch and dinner. That’s why D.K.B.’s English muffins deliver the classic taste consumers are looking for with organic, whole grain ingredients.”

New from Bimbo Bakeries USA are Entenmann’s Little Bites Churro Muffins. The limited-edition miniature muffins are dusted with cinnamon sugar and come in a box containing five pouches of four.

The Kellogg Co. has joined forces with Just Born Quality Confections to introduce Peeps cereal. The limited-edition variety features colorful marshmallow-flavored cereal pieces mixed with miniature marshmallows.

Post Consumer Brands has partnered with Mondelez International, Inc. to introduce Sour Patch Kids Flavored Cereal, inspired by the chewy sour candy. The cereal is made up of colorful Sour Patch Kid-shaped pieces with a sour coating and a sweet finish.
