WHY YOU SHOULD MAKE THIS RECIPE
- It’s made with just 4 simple ingredients you can find in your pantry or at any grocery store.
- This chocolate frosting for brownies takes just 5 minutes to whip up with the help of your microwave and a whisk.
- It truly takes a simple brownie recipe to the next level offering richness and decadence.
- It’s perfect for brownie lovers of all ages!
INGREDIENTS NEEDED
- Unsalted Butter – Makes up the creamy base of this recipe and gives the frosting its rich buttery flavor.
- Cocoa Powder – Gives the brownie icing its chocolate taste and natural brown coloring.
- Confectioners Sugar – This fine sugar blends in easily with the rest of the ingredients making it thick and smooth.
- Milk – Helps thin out the frosting to the perfect consistency while keeping it creamy.
HOW TO MAKE BROWNIE FROSTING in 5 minutes
- Prepare the butter: Add the butter to a microwavable safe bowl. Melt in 30-second intervals in the microwave until no solids remain.
- Mix the frosting: To the melted butter, add the cocoa powder and whisk until it’s incorporated into the butter. Then, add the powdered sugar and milk and whisk until a smooth frosting is formed.
- Frost: Use it to frost cooled brownies immediately. The frosting will harden on the top as it sets leaving a creamy texture underneath.
Cutting and Serving
Wait 5-10 minutes before cutting the brownies after frosting so that the icing hardens and you can make clean cuts.
The best way to cut brownies is to use a large sharp knife. Dip it in hot water, then wipe off the excess and slice the brownies. Clean the knife and repeat with the water. The residual warmth of the knife from the hot water will make nice clean cuts!
TIPS FOR RECIPE SUCCESS
- Use an offset spatula or the back of a spoon to smooth the frosting on brownies
- When melting the butter, make sure it’s not too hot. Use 30-second intervals in the microwave and whisk in between each interval.
- If your brownie frosting is too thick, add a little more milk until it reaches the desired consistency.
- If your brownie frosting is too thin, add a little more cocoa powder or confectioners sugar until it reaches the desired consistency.
- Be sure to use unsalted butter in this recipe so the brownie frosting doesn’t end up too salty.
- When frosting your brownies, make sure they are fully cooled before frosting. This will ensure that the frosting doesn’t melt off of the brownie from the heat.
STORAGE
Because this frosting hardens quickly, it needs to be used immediately. I do not recommend making this in advance.
You can store the brownies once frosted in an air tight container.

I’m making your 30 minute fudgy one-bowl brownies for the first time tomorrow. Am doubling it cuz I need more. Going to also make your 5 minute decadent brownie frosting. Wondering how big of a bowl I will need to double it?
Will rate after I make them but both recipes sound delicious & easy.
Hi Kelley! For both a double batch of the brownies and frosting you’ll need a large bowl. The frosting needs a large one because of all the powdered sugar but it will all melt once you add the cream to it. To make sure its super smooth I would also sift the powdered sugar. Can’t wait to hear how it comes out!
Ok they’re in the oven. You would think I never made anything from scratch before. Had a few mishaps as I was mixing. I did write down all the doubled amounts. Only put in 3 eggs but remembered after the dry ingredients went in. Used my hand mixer to get it all mixed in plus I didn’t have kosher salt so used regular table salt. The batter looked thicker & not as dark as yours in the video. So we’ll see. I may be buying brownies in the morning to take to this meal several of us are providing for a family after a memorial service. In general I never do a new recipe for an event. I think doubling it made it harder to manage the heavy bowl of batter. I of course will have to taste one after they cool before I do the frosting. They may not be worthy of frosting 😜
I hope it all worked out Kelley! I have doubled these before and it was totally fine. It is harder to manage liek you said with double the batter but it just means double the yummy-ness 😝
I also forgot to ask about increasing the bake time 😩
They clearly aren’t done in the middle at 25 min. Will do 10 more & check. 5min after that etc
I hope they came out ok!!!
They did turn out. I wasn’t careful enough when lifting them out with the parchment paper & had a diagonal break towards one end. Went ahead & iced & was able to cut & salvage all but a couple.
They were not
symmetrical but more organic in shape. If I could figure out how to add a picture I would.
I did love the crunchy top & fudgy center. Loved the chocolate flavor of both brownie & frosting. Will be making again 😋
Glad you liked them! They need to be totally cooled before lifting them out. Next time I would even put them in the fridge to chill before lifting them out, they will hold their shape better!
This is a excellent frosting for just about anything, soo easy & yummy. Thank you for
Thank you Leslie!! So glad enjoyed it!! SO appreciate your 5 star rating and review!
