Ghost’s protein cereal line is still young, but it is already pulling in big name cereal collabs. The latest move is a full Lucky Charms overhaul for the brand’s original Marshmallow Protein Cereal, turning an already nostalgic product into something that looks and eats like a licensed breakfast classic.
From “Marshmallows” To Lucky Charms
Ghost’s original Marshmallow Protein Cereal took a lighter, high protein take on sugary cereals. It brought:
17 grams of protein per 41 gram serving
16 grams of carbs with 10 grams of added sugar
5 grams of fat and 170 calories
A crunchy texture that held up in milk
The new version keeps that base formula but swaps in authentic Lucky Charms cereal elements. The updated box is a true Ghost x Lucky Charms crossover, not just a marshmallow flavored cereal with a wink at the classic.
What Changes In The New Cereal
Ghost is not reinventing the wheel nutritionally. The brand confirmed that the macros remain the same as the outgoing Marshmallow version. The real change is on the sensory side:
The core cereal pieces still deliver the protein and crunch
Real Lucky Charms style marshmallow shapes are mixed throughout
You get the full eight shape mix fans expect from the original cereal
That gives you the same macro friendly bowl with a much louder visual and flavor throwback.
Launch Details And Availability
Ghost is rolling out the Lucky Charms Protein Cereal in phases:
Direct launch on the Ghost website on the announced Monday drop
A larger specialty retail rollout across January
Limited but growing presence in mainstream grocery depending on partners
Like most Ghost collabs, this is expected to arrive in limited initial runs. If the Cinnamon Toast Crunch Protein Cereal launch is any indication, popular flavors can cycle in and out of stock quickly.
Why This Matters For Protein Cereal
The protein cereal space is starting to look crowded, with multiple brands promising more protein and less sugar than the cereals people grew up with. Ghost has two big advantages here:
Real partnerships with major cereal brands instead of generic knockoffs
Higher protein targets than many of the better for you players in the space
By turning its house Marshmallow flavor into an official Lucky Charms crossover, Ghost signals that this line is not a side experiment. It is a platform they plan to build on with more General Mills collabs and expanded retail distribution.
For anyone who grew up chasing the marshmallows at the bottom of the bowl, this is the grown up version that actually moves your protein intake forward instead of just your blood sugar.
