It’s literally Lucky Charms marshmallows mixed in with frosted flakes.
The boxes have hit some shelves already, but General Mills says the cereal will be available at “major retailers nationwide” over the course of the month. It’s going to be joined by a couple other General Mills hybrids: Peanut Butter Chocolate Blasted Shreds and Cinnamon Toast Crunch Blasted Shreds. Both are basically sugared-up shredded wheat. Surprisingly, the new Lucky Charms Frosted Flakes contains the least sugar of the three kinds of cereal.
