One Minute Brownie Mug Cake
by Kirbie
Yes, that’s right. I created a brownie mug cake that takes only one minute to make in the microwave. I have to confess, I’m pretty thrilled. This is my favorite mug cake creation yet. And it is still super easy to make.
It’s super chocolatey like a brownie should be. This is more like the cake-type brownies rather than the chewy brownies, but it’s still so good. When it first came out of the oven, the brownie was quite fluffy, like a really good chocolate cake. After a minute or so, the batter turns denser, much more like a brownie because of the minimal amount of flour.
I made two, offered one to the FH. At first he refused. He’s gotten kind of sick of my mug cake creations. I insisted he take a bite and he didn’t regret it. He loved it and kept the brownie for himself.
Because brownies are denser, these don’t rise nearly as much and you don’t need an oversized mug unless you want to double the quantity. A regular mug will do.
There’s one extra step required to create these cakes, but it’s still super easy and clean up is still minimal.
- 2 oz semisweet chocolate chips or chopped chocolate
- 2 tbsp unsalted butter
- 1 egg
- 4 tbsp sugar
- 2 tbsp flour
Select two microwave-safe mugs. In each mug place one tbsp of butter and 1 oz of semisweet chocolate. Microwave each mug for 40 seconds (microwave them separately). Remove and stir until chocolate is completely melted with a small fork.
Add 2 tbsp sugar to each mug and stir. Beat egg in a small bowl, add half to each mug and mix. Add in 1 tbsp flour to each cup and mix until smooth.
Cook each brownie for 1 minute in the microwave (do each separately). Serve while warm.

Yum this look delicious and so easy!
It is super easy! I was writing up the post last night and ended up making another one because I was craving it so much from looking at my pictures. haha
Just the BEST says my 9yr old Granddaughter who made for our family of 4
OMG… this looks so good! I have been looking for a good mug brownie recipe and this looks great. Thank you!
I hope you enjoy it!
Canine Cologne mentioned that you had another version so I had to come check it out. Next time I want just a single serving of brownie, I’m so making this!
This is a bit dangerous. Now I can have brownies whenever I want.
I did what u said and for what ever reason it didn’t come out cake like .. it was just a blob .. what did I do wrong?!
I’m sorry to hear that. Without watching what you did, it’s hard for me to say. What do you mean by a blob? Did it cook thoroughly? Is it hard? I’m wondering if it is something with the microwave time. I’ve made this many times with no problems.
I tried it and it’s so good the only problem was I didn’t have any semi sweet chocolate so I used dark, and so it’s not that sweet but next time I will try it with the right kind
Oh, I think dark chocolate can work too, but maybe add a little more sugar to it. I’m glad you like it though!
I tried to make just one serving and i used a whole egg for one cup. it came out kind of blobby but kind of cakey after i put it in the microwave for another 3o secs. I also added a little more flour because i thought it would help with the egg. Maybe i’ll stick to the recipe next time.
I think a whole egg is a little too much for this recipe and you have to double everything. Perhaps you try putting it all into one oversized mug if you dont want to divide the egg
I’m so excited to try this, but I don’t think I have any chocolate chips or bars in my house. Do you think I’d be able to usse unsweetened cocoa powder instead?
Hmm I don’t thnk it would come out the same unfortunately. And i think the recipe would need to be changed up a lot too
Sorry not very good…..
That’s too bad
I tried with cocoa powder instead of chocolate chips. I should have added more liquid to compensate for the extra dry ingredients. It came out a bit dry and cakey (still edible for sure though). As a stroke of genius though, I put in a werther’s original and the area surrounding it was something special!
Hmm, I’ve never tried this with cocoa powder, so I imagine it wouldn’t come out exactly the same. If you’re looking for a cocoa powder recipe, try the flourless chocolate mug cake. https://kirbiecravings.com/2012/02/fancy-flourless-chocolate-mug-cake.html
Thought it was awesome! Me and my husband loved it! Why even comment if you didn’t like it? People are so weird. Just don’t make it. Duh!
I’m glad you liked it. =) I’m not fond of negative comments either.
Is it possible to substitute the egg for something else? I was telling a friend of mine the amazingness of this recipe, but due to religious believes, she doesn’t eat eggs. So is there any way to make this with out the egg or replace it with something else?
I honestly don’t know the answer to that. I’ve never made brownies or cakes without eggs before. There may be a way, but I haven’t tried it.
Try a flax egg. https://minimalistbaker.com/how-to-make-a-flax-egg/
Also if you like chewy brownies try brown sugar. It was great!
So Ive been searching your blog and I think I may just of fallen in love, what your doing is everything I want to do. It’s so creative and new and it’s really just the best. I just thought I would let you know that your blog is amazing, keep up the good work!
Aw, thank you for taking the time to tell me. Your kind words definitely made my day!
I know I am late to the game but I have to say these are amazing. I haven’t found one of your mug cakes that I haven’t liked but I think this is the best of the bunch. I think I will go so far as to say it’s better than regular brownies.
This is one of my favs. Probably this one and the flourless nutella one. I’m happy to hear you like them!
Instead of using butter, I used vegetable oil instead, and they turned out just as great! I’m going to try the Brownie Nutella Lava Cakes next!
This is my third Kirbie mug cake in the last week or so lol. I stumbled across your blog and am so happy I did – every recipe turns out great and absolutely perfect for a sweets craving. Also, I also live in SD, too! So thanks a bunch, neighbor! 🙂
That’s so great to here! And I love that you’re in SD too!
DELICIOUS! Worked perfectly, and just in the nick of time — we were craving a sweet treat, and I had nothing prepared! Disaster averted, and a new favorite late night treat found!
Nice!
Great base recipe! I was craving cream cheese swirl brownies, and I only wanted to make one serving, so what I did was melted a little more than a tbsp of chocolate chips with 1 tbsp butter, then added 1 1/2 tbsp sugar and half of the egg, then added 1 1/2 tbsp flour. I also added just a splash of vanilla extract and a dash of salt. With the other half of the egg, I added 1 oz cream cheese and 1/2 tbsp of sugar, mixed that well then swirled it in with the brownie mix. Microwaved for 2 min. INCREDIBLE! Thank you for the inspiration 🙂
Nice! I didn’t even think of trying to make cream cheese swirled brownies in the microwave.
I put everything in one oversized mug and microwaved for a minute and a half… It was semi cooked but still awesome!! Thanks a lot! 😀
Hmm, not sure why only semi cooked, but glad you liked it!
OMG this was amazing, I tried it for the first time and my mom absolutely loved it, garnished it with Bounty and MnMs 😀 thank you so much for the recipe, i discovered your blog yesterday, love it!
That’s so great to hear! This is one of my favorites. It’s so dangerously easy.
Tried this with ghiradelli chocolate chips, so good!! Though for me, I think next time oi I’ll reduce sugar cuz I like my warm brownies with a scoop of vanilla bean ice cream 😀 so good!! Chocolate craving satisfied!!!
Nice! Ice cream sounds good
I just made this using dark chocolate chips and I added pecans. It was so darn yummy! Thanks so much for sharing the recipe!
Any idea how many calories is in this?
There is a good calorie counter program https://caloriecount.about.com/cc/recipe_analysis.php
hey! it looks and sounds soooo good and easy, but there`s one problem – i have no microwawe.. ;( so mby you know in what temp and how long i should bake this? thanks 🙂
Sorry I’ve never tried baking it. I would imagine 350F, which is standard for brownies, but I don’t know how long.
I just want you to know you’re awesome. This is amazing. Eating it now!
Aw, glad you like it!
Did this today but with a twist! Instead of using semi-sweet chocolates, I used cinnamon chips and it was amazing. Especially when it’s topped with whipped cream and sprinkled cinnamon. Thanks for the recipe!
Oooh, sounds great!
OMG!!!! I only had dark chocolate chips but it still ROCKED! You are so awesome.
I’m so glad you enjoyed it!
Oh my, I was Googling recipes looking for a quick remedy to my chocolate craving – something smaller in portion than a whole batch of brownies – and am thoroughly delighted to find this. Thank you!
So glad I could help!
it taste so good
it taste better if you add 1 teaspoon or 2 wben it finish and mix it up. YUMMMMMMMMMM!!!!!!!!!!!!!!!!!!!!!!!
a tsp of what? the batter?
I tried this, and it came out a little strangely; there were bits of cooked egg weirdly strewn throughout. I think I may have added the egg before the sugar on accident; could this be the cause? Thanks!
It sounds like it wasn’t mixed completely. If it’s completely mixed, you won’t able to see or taste any egg.
Your recipe is fabulous!! My brownie mug cake is like a one that made by the oven!!
I have made brownie by using the microwave many times, but the texture is not good.
Thanks do much for your recipe.
PS. I have planned to make brownie cheesecake, I will use your recipe for brownie-base, hope it work ^^
So glad you enjoy this!
I just tried making this with gluten free all-purpose flour and vanilla and all I have to say is…FABULOUS! It was so good I almost forgot I was gluten free! Thank you!!!!
I will have to try this with gluten free flour next time!
I make this cake WAY too often! The hubby wanted something sweet after he got home late from work…this always does the trick! What a great recipe!!!
I’m so glad you and your husband are enjoying this recipe =)
Being more of a chocolate fiend than sweets, I make this with 70% dark chocolate, 1.5 Tbsp sugar, and add splash of vanilla and salt and it comes out and it comes out dangerously good and easy.
I’m glad it came out well for u!
I mean for a single serving
How many tsp of chocolate (aprox.) is 2 oz?
Not sure..also I don’t think you’re going to get a very accurate measurement using tsp with chocolate chips, especially with their irregular shape, which is why I always weigh it out
I absolutely adore this recipe. I have a serious cinnamon addiction, though, so I substituted half of the chocolate for cinnamon morsels. The result was glorious, especially after I added more on top of the hot brownie.
I’m glad you enjoy it so much!
Thank you, thank you, thank you!! I’ve been searching for microwave mug cake recipes that don’t taste rubbery or just plain bad. This one was awesome! The texture and taste were absolutely perfect! This has just become my go to recipe for late night cravings!
You’re welcome! I hope you try out some of my others!
I made one jumbo brownie in a large mug and it is way too deadly. Someone save me! This is amazing!
so glad you like it!
This was perfect! So yummy and convenient!
so glad you liked it!
This webpage IS SO OVERLOADED WITH ADS it is difficult for my computer and I have a top notch laptop…urrr…. However, this recipe was the best I have found so far!! LOVE IT~
what web browser are you using? i dont have a top notch laptop and i dont have issues with it loading any slower than other blog sites.
Seeing as I made this at 2 am, with nobody to share it with (Bummer…NOT!), I used a bowl for the double serving ( took 2min instead of 1 no biggie) and having no semisweet chocolate (not a fan of semisweet chocolate) I used a regular milk chocolate bar i had, kept everything else the same and it turned out AMAZING!!!
So glad you enjoyed this! I think it’s much better for one person than having to share!
Can I use brown sugar and mix it with the white?
I recommend making the recipe as is and then you can try diff versions and see how it compares. brown sugar will change the texture of the brownie.
Lovely basic recipe it supresses my midnight snack craving. I added .5 oz more chocolate than the recipe but I figured it would be harmless. I’m not sure if I didn’t cook it long enough or it was the extra chocolate but I think next time I’ll add a little more flour and maybe some vanilla.
Adding more melted chocolate to the recipe would require you to adjust the flour as well.
Sitting here with a sweet tooth, searching for something with minimal ingredients and happened upon this. I’ve never made a mug cake, or brownie. Such a pleasant surprise, this was! Near the bottom, it’s just like a lava cake. Thanks Kirbie 🙂
Yay, so glad you enjoyed this!
loved this recipe! made it at home in only 5 minutes! the texture was a little spongy, but i think that was only because i added too much egg to my mug. other than that, tasty and easy!
xoxo, Sophia
adding too much egg would make the texture more spongy. But I’m glad you liked it!
This recipe is sooooo awesome.
I made the brownie and it tastes so good.
I love it.
Thank you for such a wonderful recipe
I’m so glad you loved it. It’s one of my favorites!
Literally all the perfect quality of a brownie done in less than a quarter of the time it would take to make brownies from the box. Plus, i’m not stuck with a whole batch justin waiting to be eaten day by day. Soft, chewy, and chocolatey.. so yummy. i wish i came across your website when i was pregnant because your recipes would’ve been my go-tos!!!
I’m so glad you enjoyed it! It’s one of my favorites!
