These chocolate brownies covered in rainbow sprinkles bring back memories! I have fond memories of picking out the weekly grocery store snack when I was a kid, most often reaching for a box of Little Debbie Cosmic Brownies! What wasn’t to love about these brownies? They were chocolate! They were soft! They had rainbow sprinkles! They had “Cosmic” in the title! They were so cool!
Whenever I’m in the grocery store now and I walk by the display of Little Debbie pastries, my eyes always dart to quickly find the Cosmic Brownies. I usually smile quickly and move along. This time though, I decided I was going to make my favorite childhood brownies! Enjoy these Homemade Copycat Little Debbie Cosmic Brownies!

2 things always call out to me when you see a cosmic brownie: the frosting and the sprinkles! Let’s talk frosting first!
Little Debbie brownies always have a shiny, rich layer of chocolate fudge frosting on top. We’re making a similar frosting for this recipe that’s going to be just as shiny as the packaged brownies! When you pour the frosting on the brownies let it sit for a few minutes to set completely. You can even put them in the refrigerator for a few minutes to set them quicker!
The other thing that makes Little Debbie Cosmic Brownies special is the sprinkles! I used cosmic ball sprinkles on them, as well as added rainbow sprinkles for my own personal touch! The ball sprinkles are a little hard to find, but if you have a baking store they will most likely have them! Amazon of course has them. If all else fails, you could use Sixlets candies!
Can you put sprinkles in the oven? I recommend not adding the sprinkles on these brownies until after you pull them from the oven – this will result in much brighter colors and prevent your sprinkles from melting!
How many calories are these Little Debbie Cosmic Brownies?

Hi, just wondering how the recipe turned out? Similar to the original? Thanks!
Yes they were
These looks so thick and rich. My daughter was just asking me to make brownies and I know she will love the fun toppings too.
I made these brownies last night with my kids help and they turned out so good! I didn’t have the right sprinkles that cosmic brownies use but I used regular rainbow sprinkles from the store. Thank you!
Is it baking powder or baking soda ?
Hey Lorraine, it’s baking powder. Enjoy the brownies!
My frosting is very thick. I don’t think I can spread it on the brownies. What should I do?!
Never mind! All I had to do was add a little bit more melted butter and it spread on perfectly!
Great to hear! Hope you enjoyed the brownies Opal!
