Copycat Cosmic Brownies are a rich and fudgy blast from the past! They are just like the ones you remember from childhood that are ultra dense with a deep chocolate flavor. They’re topped with chocolate ganache and finished with a sprinkle of colorful candies.
Summer is coming to a close and that means I need to start thinking about going back to school. I’ve been looking for some copycat recipes of favorite lunchbox treats and had a few in mind to work on.
One of the recipes I wanted to make were Copycat Cosmic Brownies. Not only are these brownies delicious, they have fun colored candies on top!
What are COsmic Brownies?
Cosmic Brownies are a popular lunchbox snack made by Little Debbie. These dense, fudgy chocolate brownies are topped with a layer of smooth chocolate icing and sprinkled with colorful candy-coated chocolate chips (sometimes called rainbow chips).
Now it’s not like I don’t have a ton of brownie recipes already. For a quick brownie I make Air Fryer Brownies with Pecans. When I want just a great frosted brownie I go for the Malted Milk Brownies. My favorite brownies, which I don’t make all that often, are Chocolate Chip Cookie Dough Brownies.
Did you ever have a Cosmic Brownie as a kid? They are made by Little Debbie and they were like gold in lunchboxes. If you had these in your lunchbox you could definitely trade for a treat you didn’t get often at home.
As I made the brownies I realized there was no baking powder in them and that they were going to be flat just like I remembered them. Not only were they flat but they were rich and really tasty.
Then the thick ganache on top with the sprinkles really made them look like the classic Cosmic Brownies. They tasted similar to classic Cosmic Brownie but more homemade and better. My husband and I enjoyed several of these.

Notes








Oh my this brings back some memories! I bet these are way better!!
They are really, really good.
What cute little brownies!
I have made homemade Cosmic brownies! They are so much better than the real thing. 🙂
I was obviously a deprived kid! I’ve never had these scrumptious looking brownies, but I know my whole family will go nuts over them when I make your recipe! Beautiful presentation and very fun!
If you’ve never had them you need to try them! They are yummy!
Yes, yes, a million times yes! I will be making these – saving them for the next time I see my brother. Definitely our childhood favorite lunchbox treat.
So glad to have met you and your husband in person last week! I hope you guys enjoyed yourself and learned lots.
You know, I’ve never seen these from Little Debbie but I really hadn’t looked. I’m intrigued by the omission of the baking powder. They look delicious!
So glad to have met you too! It was an amazing weekend! I think leaving out the baking powder in the brownies is what makes them thin, fudgy, and delicious!
I missed out on Cosmic brownies as a kid! SO glad I can make them after today!!!
I want one now 🙂
I haven’t thought about Cosmic Brownies since my son was in grade school. Oh boy, he loved these in his lunch box!
Your brownies look amazing, and I can’t wait to try your recipe! I know my son will love them, and of course, I will!!
Love those fun sprinkles and that thick layer of icing!
I loved cosmic brownies. I actually forgot about them until I saw your post. Little Debbie made it into my lunch box so many time when I was a little girl. Thanks for the memories.
Yup, sure have had one of these! What a nice treat for your hubby’s student!
