These rich and simple Rainbow Chip Brownies are chewy and fudgy made even sweeter with chocolate frosting spread on while the brownies are still warm! Topped with Rainbow Chips makes them adorable and colorful, like Cosmic Brownies only WAY better!

My kiddo loves Cosmic Brownies, possibly (even more than my homemade brownies recipe). You know, the ones by Little Debbie. I could have literally baked 3 pies, 2 cakes and a batch of sugar cookies and if there are Cosmic Brownies in our pantry my littles will bypass all the homemade goodness for strangely glossy brownies inside cellophane wrappers. They have magic in them for sure.
Clearly the obvious choice here is to not PURCHASE the Cosmic Brownies in the first place. Yes, duh, I get it…but I feel like Little Debbie is an essential part of the childhood experience. I mean Oatmeal Cream Pies and Star Crunch were regulars in my lunchbox and I think I turned out pretty normal-ish. So yes, they do make an appearance in our pantry from time to time only to be devoured by my alien children in a day and a half.
But since Little Debbie makes me feel like a Bitter Betty when my kids go for her treats over mine I decided to come up with my own Cosmic magic situation. Turns out the answer is frosting and Rainbow Chips. Isn’t it always?
These super simple brownies are a play on my kid’s favorite brownie recipe topped with a trillion little candy coated chips. I have to say all the colors make them pretty irresistible.
The brownie batter is simple. I use a mixer but you absolutely don’t have to…
Just spread the brownie batter in the pan and bake them up. They don’t take long.
Then make your quick frosting and spread that on the brownies when they’re warm. Trust me on this…the frosting will partially melt into the brownies and you’ll get omg deliciousness.
Then sprinkle rainbow chips all over. Do this immediately, so they stick to the frosting!
Let them cool and they slice up like a dream…
My kids totally approved.

There is something about those Cosmic Brownies because my kids love them too! I love that bright rainbow chips and use them every chance I get. Love the fun pop of color on the chocolate brownies!
Mmmm! Delicious and ultra colorful! Yummy yummy yummy!
My boys too, prefer packaged goodies to homemade goodness. Maybe it is the wrapper? There’s no way they would turn down something with frosting and colored chips. Thanks for the recipe.
