These homemade Frosted Rainbow Chip Brownies are topped with dark chocolate frosting and colorful chips making them so rich and delicious. This copycat recipe for Cosmic Brownies is the perfect snack for lunch boxes, after school snacks, or bake sales.
Our youngest son loves brownies and always wants to help me make them. The other night he got a box out of the cupboard and made them all by himself with some supervision from me.
Then he proceeded to eat quite a few before they even had a chance to cool off. Plain brownies are definitely his all time favorite dessert.
The next day on the way to school, he said that now that he knows how to make brownies, he is going to get up in the middle of the night and make his own pan. Sneaky little monster!
I admit that most of the time I like to reach for a box mix too. But ever since I made these Homemade Chocolate Chip Brownies, I have been converted to homemade brownie making. They are the perfect brownie to use for every chocolate craving you may have.
Although, there are still a few box brownie mixes in my cupboards that I will be using from time to time. Let’s not get too crazy excited about homemade all the time. After all, my baking motto is semi-homemade with flair!
These frosted brownies are definitely a favorite around my house. Although, my hubby took one look at them and wanted to know why I added rainbow chips to the entire pan of brownies.
He must be an alien or something because he hates any sort of sprinkles. That alien gene has been passed down to our kids because the boys always pick them off too.
A few years ago I made a pan of these Frosted Rainbow Chip Brownies for our life group AND a pan for a blog retreat.
The running joke from everyone in both groups was that I just unwrapped a package of Little Debbie Cosmic Brownies, put them on a plate, and brought those because these were too perfect looking.
The fun little colorful rainbow chips do totally make these look like those prepackaged childhood treats…except mine taste so much better. You have to check out my copycat Oatmeal Cream Pies recipe too. They are amazing!!!
These chewy frosted fudge brownies are the real deal. Homemade and absolutely delicious!!! Even with rainbow sprinkles!

It’s so great that your son is getting the baking bug from you! Nothing is better than a fresh pan of brownies. And they are crazy for not being into the rainbow chips. That makes brownies so much more fun!
He definitely is the baker out of the three of our kids, and he cracks me up with his love for brownies.
I’ve never seen rainbow chip sprinkles, Jocelyn, but I love them! They’re so bright. These brownies look amazing. I can’t wait to try them. 🙂
Thanks Erin. I buy the rainbow chip sprinkles at Michaels and JoAnn’s. Hope you can find them!
These look so moist and delicious!! Love those rainbow candies on top!
Thanks Rachel. These brownies are definitely delicious 🙂
You think kids would love the sprinkles! So funny!
I know, right? Bunch of crazies I’m living with here 🙂
I totally agree with your random Monday rules, Jocelyn! If only work didn’t get in the way! 🙂 These brownies look delicious! Love the rainbow chips on top. Pinned!
Work does tend to get in the way of things, doesn’t it? Thanks for sharing!
Such fun brownies! I love the rainbow chips 🙂
Thanks Amanda!!!
such a cheery brownie for a Monday morning!
I have a bag of those beautiful little rainbow chips waiting to go on top of some brownies! And I love your idea of a Monday. 🙂
Woo hoo! Sounds like some brownie fun is happening soon for you then 🙂
I agree with all those things. So why are my to-dos screaming at me???!!! Love these brownies girl, you know how I am with brownies!
Uuuggghhh I hear ya on the to-do list. I have a bunch of things that I need to get moving on!!! Let’s just do brownies instead, ok?
These brownies are making me smile! I love the fun rainbow chips on top and just look at how fudgy the brownie is!
Can I substitute sugar for no sugar , sugar?
Are you wondering if you can use a sugar substitute??? I have never made these brownies with anything other than regular granulated sugar. But I have been using Monkfruit sugar and I think that is one that can be used one for one in place of regular sugar. Stevia is another one, but that one you have to use half regular and half Stevia for it to bake right.
Jocelyn these are so cute!!
I wish my Monday list looked like that! I’m busy getting things in order to go out of town. Like cleaning, lol! I love these brownies-they remind of those Little Debbie like ones they sell at the store that are sooo good!
I know exactly what you mean. There is always so much to do before a trip. Haha! Yes, these do look like the packaged ones…everyone was teasing me about just unwrapping those and serving them to our group.
So I’ve followed every one of your Monday rules except for eat brownies. Time to change that!
Woo hoo! I’m glad you are on board with the Monday rules…better get that brownie though!!!
These do look perfect! And your son is way to funny! Sneaky is right!
You always have the cutest desserts! Love these!
Thank you so much 🙂
Ahhh, I love these! Let’s see, I drank lots of coffee and wore sweat pants all day – that counts, right? I could definitely go for brownies though!
Yup, that totally counts…but you need to get that brownie action happening 🙂
who hates sprinkles???????? These brownies do look delicious tho, I don’t think I have seen these sprinkles in any stores around here, I will have to search online.
I know, right? I bought the rainbow chip sprinkles at Michaels, and I think I have seen them at JoAnn’s too. There is also a link above where you can buy them from Amazon if you need 🙂
These look SO good!! Intense and fudgy, just the way I like my brownies!!
Now, you must know that rainbow is my favorite food group. These look like a homemade version of little debbie “Cosmic brownies” (yes, I have been known to partake)
I like your food groups 🙂 And yup, these are totally like those cosmic brownies, but better since they are homemade!!!
Definitely agree with you about every Monday needing some decadent brownies!! 🙂 I love these homemade ones, and the rainbow sprinkles make them look absolutely perfect!
Major love for these fudgy brownies!
That sounds like an ideal way to spend a Monday 🙂
The brownies look absolutely perfect! Love the rainbow chips!
Where did you find the rainbow chips? I’ve never seen those to buy….
Hi, Hali. I bought the rainbow chips at Michaels, and I think I have seen them at JoAnn’s too. There is also a link above if you can’t find them and want to order them on Amazon.
Why can’t those rules be for every day, not just a random Monday?? 😉 Love how fudgy and decadent these brownies look! Pinned!
I am totally down with these rules applying to every single day 🙂 Thanks for the pin love girlie!!!
Yum, these look delicious! Cosmic brownies were my favorite when I was a kid, I can’t wait to make this from scratch version!
What brand of cocoa powder did you use? I can’t seem to find dark chocolate in the store!
I used Hershey’s dark cocoa, and I think I found it at Walmart. Although I think most stores have it too.
These brownies with 1/2 cup heavy whipped cream and 1 cup chocolate chips (for frosting) Do you have to refrigerate ?
No, you do not need to refrigerate the brownies, unless you really want too. I hope you enjoy the treats!
