How to make cosmic brownies?

This question has been in my mind for about a week now!

I’ll tell why I had to come up with my own homemade cosmic brownies version, but let me just say these are really chocolatey and not too sweet! And the chocolate frosting is absolutely delicious!

Full disclosure, I’ve never had a cosmic brownie! I’ve never even heard of them until recently!

So, why am I suddenly interested in cosmic brownies?

I was watching a video by my fellow YouTuber The Vintage Vegetarian where he reviewed them. And they looked absolutely delicious!

The Vintage Vegetarian: Little Debbie’s Cosmic Brownies Food Review!

So, why not buy them and be done with it?

Well, I live in Portugal, and we can’t buy them here! So, I had to make my own!

Are my brownies even close to the original? I have no way of knowing, but they are delicious brownies, and that’s enough for me!

What are cosmic brownies?

Cosmic Brownies are rich, fudgy and dense chocolate brownies, topped with chocolate frosting and rainbow sprinkles. They were popularized by the Little Debbie Company.

Some notes on how I make homemade cosmic brownies

If you know me, you know my lazy approach to baking: if possible, everything in one bowl and mix.

But, by all means, if you insist, mix the dry ingredients separately and add them to the wet!

I use all brown sugar, but you could use half brown and half granulated! They’ll probably be sweeter!

If you manage to pay enough attention, don’t overcook the brownies. If you do, don’t worry, you’ll still have a delicious chocolate cake.

I don’t have any sprinkles, I usually have no use for them! But I had some rainbow candy my father brought me from turkey, so I smashed it with a rolling pin and pretended they were sprinkles! Cooking is improvising!

Ideally, you should refrigerate the brownies before cutting, but I won’t judge you if you don’t, I know I didn’t (as you may see in the pictures)!

That being said, they are actually better when you keep them in the fridge for a bit!
