This is the Best Ever Brownie Frosting, and I am not messing around. Rich and fudge-like, this frosting is insanely delicious! Get ready to lick the bowl clean.
This rich chocolate frosting is silky smooth and simple to make. Taking just 10 minutes to make, and it will add a layer of wow to your brownies that everyone will love.
My dad made this Best Ever Brownie Frosting recipe for as long as I can remember. I have never had a brownie that was better than my dad’s. When I got into college, I decided it was time to learn to make my dad’s brownies.
As I phoned my dad and asked for the frosting recipe, he was delighted that I wanted to make them. What surprised me, even more, was him telling me it could be made in a microwave – this gave me less of an opportunity to ruin it! So then, I asked about his brownie recipe – something unexpected happened. My father informed me he used a ready-made brownie mix?! Unbelievable!!! My dad used a brownie mix! WHAT???
Honestly, I was shocked; how could this be? Why, why on earth did I think they were homemade? Because they were my dad’s brownies. He said he always just used Ghiradelli brownie mixes and then made homemade frosting to give it that homemade taste. Well, it is the frosting that makes it oh, so amazing! His brownies, to me, are still the bomb and can’t be beaten.
Since then, I have used Ghiradelli brownie mixes just like my dad’s brownie frosting. I also use the same brownie mixes in my Fudge Brownie No-Bake Cheesecake; it’s one of my absolute favorite recipes.
I have continued to make my dad’s brownies throughout the year. And everyone loves this best-ever brownie frosting. So while I would top a chocolatey brownie with anything else, you could add sprinkles on top of this chocolate frosting; my girls sure love them this way.

There are lots of frosting options for brownies, but this Best Ever Brownie Frosting is my favorite because it’s easy to make and perfectly rich without overpowering the brownies. buttercream frosting or chocolate whipped cream also make delicious toppings.

I had to know where my dad got this recipe for brownie frosting, I mean, he is a fantastic cook, but he has never just made up a dessert recipe; he does make a lot of savory dishes, but sweet ones he always has a recipe.
I was not surprised when he said he got the recipe from Jean, one of our longtime family friends. Jean does have some of the best dessert recipes. I am utterly obsessed with her recipe for Pumpkin Bars.
Let me tell you this brownie frosting elevates your brownies in that it makes them irresistible. Trust me when I say you won’t have any self-restraint and end up licking the bowl clean – that’s what I do every single time!

Does this recipe make enough to frost a sheet pan (18x13x1-1/2″) of brownies or should I double it?
The recipe will be enough for you pan size. It is the pan size I use as well.

Does the frosting sort of harden so you can stack the brownies in a tin?
Yes, it will harden. Layer with parchment paper though. Enjoy! San
Made this for the first time this evening. I did not have buttermilk, but made my own by mixing milk and lemon juice (1 cup milk & 1 T lemon juice, set for 10 min) and measured amount needed. The icing poured so easily, but I had to spread and work quickly to cover my large double batch brownie pan before it set. All in all it looked really impressive! Better yet, it tasted delicious! My four teens loved it and their friends sang it’s praises. My husband loved it too! The icing really makes a simple box brownie seem like a professional treat. Thank you.
Hi, I may have missed it but how many boxes of brownie mix do you make for that size pan? And would you put the toppings on immediately after or would you let it sit for a while? Also do you put it on hot brownies or cooled?
Follow the instructions on the box for the pan size. Smaller pans will make thicker brownies, and a 9×13 pan will make thinner ones. I would let it cool while making the frosting, otherwise it may take longer to set the frosting.
This will be perfect for my next brownies, thank you so much!
I hope you enjoy it!
OH MY looks SO yummy!
Thanks!

Best Brownies ever! I have been cooking and baking for over 50 years. My friends and family say I am a very good cook. But these are the best and easiest brownies I’ve made. Thanks for sharing the recipe. Turned out just perfect. and I did’t have to use a mixer!
I am so glad you like them and that they turned out well for you! Thank you!
I sent brownies with this frosting to a school party. Big mistake. Now I have to send brownies to EVERY party! My son’s classmates and teachers beg him to bring brownies! It’s so delicious and a great way to make simple box brownie feel fancy.
I’m so glad the kids enjoyed it! It really is the best. Thank you!
I have made this several times since happening upon the most delicious & amazing brownie topping , turns out perfect every time ! Thank you so much for this recipe !
I’m so happy that you like it! It really is addictive. Thank you for reading!
This frosting is fantastic! I’ve used it on several batches of brownies and I even made a chocolate poke cake with it!
Where has this been my whole life. We loved every bite!
Looks impossible to resist! Everyone would definitely love this!
Oh wow! These brownies are insanely delicious!! My favorite treat!
Oh my goodness!! This sounds AMAAAZING!!
This is definitely the best addition to a brownie! It works with cakes too!
Delicious. Quick and easy to follow.
Can I freeze leftover frosting and then reheat it for later use?
Oh, I am really not sure, I have never tried that.
Great frosting recipe! Melting the butter really shortened the time to make frosting. Since it was already melted, I was able to frost my brownies when they were still warm. (I also added a little bit of espresso powder with the chocolate powder)
Absolutely amazing and so easy. We loved it!
this brownie frosting recipe sounds amazing!
That microwave aside made me smile because you keep the frosting from feeling fussy or intimidating. The little shock of your dad using a boxed mix makes the homemade frosting shine even more.
