REVIEW: Kellogg’s Little Debbie Cosmic Brownie Cereal

What is Kellogg’s Little Debbie Cosmic Brownie Cereal?

It seems like everything is getting a reboot these days. Maybe it’s your favorite old movie, maybe it’s a nostalgic toy… or maybe, just maybe, it’s a beloved childhood treat. If you’re excited for option three, then we have news for you. Little Debbie, maker of the classic Cosmic Brownies, is teaming up with Kellogg’s on a new Little Debbie Cosmic Brownies cereal. It’s mini brownie squares complete with rainbow pieces to look like the original.

How is it?

As I opened the bag, I first noted this: If you were conducting a blind sniff test, I’d think this was a bag of Cocoa Puffs. It’s a strong whiff of chocolate. Now, obviously, I had to buy a box of the original Cosmic Brownies for true comparison. (I was surprised to find out that my husband had NEVER tried the brownies, which makes me wonder how sad his sack lunches were growing up…) I tried the brownie and immediately followed it with the cereal.

While the texture of the actual brownie is very fudgy and soft, what you’re getting here is a standard, crunchy cereal that feels like anything else you find on grocery shelves. You might as well close your eyes and play eeny, meeny, miny, mo with a handful of chocolate-based cereals, and you wouldn’t know this was supposed to mimic the brownie.

I noticed a strong cocoa taste that is sweet without being TOO sweet, which I liked. The nutrition facts back it up – only 14 grams of sugar in a serving. Sadly, the rainbow pieces are so small that they added no impact or flavor to the cereal.

In terms of rating – while it doesn’t taste exactly like the original brownie, it still tasted pretty good for a fun cereal. I knocked points off for the comparison, but not for the taste alone when you separate that concept.

Anything else you need to know?

Definitely add milk if you do want it to have any semblance to the brownie. A splash of milk helps soften the cereal and bring out the fudgier taste I was desiring. Unfortunately, the flavor stayed mostly with the cereal, so the milk at the bottom of the bowl ended up being not very chocolatey.


If you like chocolate cereal, Kellogg’s Little Debbie Cosmic Brownies is worth a try. But if you’re coming for a replica of the original, you might be disappointed.

  1. These look like Fun with a capital F even if they didn’t quite nail the replication. It is disappointing to hear that they didn’t create epic chocolate milk but sound like they’d make a great snack.

    Thank you for enlightening your husband on the joys of the Cosmic Brownie.

  2. I don’t know. These looked pretty unimpressive in general. Most of the snack cake cereals really weren’t great in general. I had higher hopes for the Little Debbie Oatmeal Pie cereal, but even that was “meh”.

    I feel like it’s been so long now that I’ve tried a new cereal I’ve fallen in love with and can eat a whole box in a sitting. That’s probably a good thing, but even still, no new recent releases have wowed me in recent years.

    Tropical Froot Loops, Cotton Candy Cap’n Crunch, Orange Creamsicle Cap’n Crunch, and maybe one other I’m forgetting were like the best releases in recent years in my opinion.

    Looking forward to Caramel Corn Pops coming out soon and the new Ghostbuster’s Afterlife Cereal hitting the market soon. The Frosted Flakes with the Cinnamon balls were decent, but not great.

  3. 10/10 review, great read. This review literally had everything I need to know, thanks!!
