But WHY Minneapolis-based General Mills is pulling three flavors of Cheerios from store shelves is not clear. According to Instagram's the_cerealqueen -- Kayla Simonson -- the General has axed three popular flavors of their Cheerios brand of cereals:What made these three Cheerios varieties unique and special? Simonson calls Chocolate Peanut Butter Cheerios "fantastic" and says they pack more flavor than rival Reese's Puffs -- also made by General Mills. Simonson calls Honey Nut Cheerios Medley Crunch "so underrated," praising the Honey Nut Cheerios, multi-grain flakes, and honey clusters of granola with almonds. And Simonson says she could maybe see why Honey Nut Minis were ended because of the popularity of the original Honey Nut Cheerios they competed with.
