Post has partnered again with Hostess Brands, L.L.C. to bring the Twinkies brand to the cereal aisle in late December. New Post Hostess Twinkies cereal replicates the taste and oblong shape of the golden-colored snack cakes and contains 180 calories and 16 grams of sugar per 1-cup serving.

We think fans will find that it not only tastes great with milk but also outside the bowl."
