Yes that’s right. I creates 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 more dense, 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.

      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

    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!

    • Kirbie replied: — December 21st, 2011 @ 10:15 pm

      This is a bit dangerous. Now I can have brownies whenever I want.

  4. Shannon Cavallaro — December 25, 2011 at 2:29 pm

    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?!

    • Kirbie replied: — December 25th, 2011 @ 10:59 pm

      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.

  5. Nicole LaVigueur — January 8, 2012 at 11:35 am

    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

    • Kirbie replied: — January 8th, 2012 @ 4:16 pm

      Oh, I think dark chocolate can work too, but maybe add a little more sugar to it. I’m glad you like it though!

  6. Glory — January 27, 2012 at 6:40 pm

    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.

    • Kirbie replied: — January 27th, 2012 @ 10:35 pm

      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

  7. Seema — February 12, 2012 at 5:27 am

    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?

    • Kirbie replied: — February 12th, 2012 @ 2:16 pm

      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

  8. Carrie — February 19, 2012 at 3:08 pm

    Sorry not very good…..

    • Kirbie replied: — February 20th, 2012 @ 10:28 am

      That’s too bad

  9. Janine — February 26, 2012 at 8:39 am

    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!

  10. Beth — March 1, 2012 at 6:11 pm

    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!

    • Kirbie replied: — March 2nd, 2012 @ 6:12 pm

      I’m glad you liked it. =) I’m not fond of negative comments either.

  11. Nicole — March 11, 2012 at 7:14 pm

    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?

    • Kirbie replied: — March 12th, 2012 @ 7:48 am

      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.

  12. Tess — May 16, 2012 at 4:02 pm

    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!

    • Kirbie replied: — May 17th, 2012 @ 10:50 am

      Aw, thank you for taking the time to tell me. Your kind words definitely made my day!

  13. Carrie N — June 26, 2012 at 9:32 am

    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.

    • Kirbie replied: — June 26th, 2012 @ 12:49 pm

      This is one of my favs. Probably this one and the flourless nutella one. I’m happy to hear you like them!

  14. Trisha — August 14, 2012 at 9:32 am

    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!

  15. Jessica — August 30, 2012 at 7:59 pm

    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! :)

    • Kirbie replied: — August 30th, 2012 @ 9:45 pm

      That’s so great to here! And I love that you’re in SD too!

  16. Alicia — September 3, 2012 at 5:26 pm

    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!

    • Kirbie replied: — September 4th, 2012 @ 8:27 am

      Nice!

  17. Colleen — October 26, 2012 at 3:24 pm

    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 :-)

    • Kirbie replied: — October 26th, 2012 @ 3:28 pm

      Nice! I didn’t even think of trying to make cream cheese swirled brownies in the microwave.

  18. Simran — November 4, 2012 at 4:15 am

    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! :D

    • Kirbie replied: — November 4th, 2012 @ 11:38 pm

      Hmm, not sure why only semi cooked, but glad you liked it!

  19. minahil — November 16, 2012 at 5:00 am

    OMG this was amazing, I tried it for the first time and my mom absolutely loved it, garnished it with Bounty and MnMs :D thank you so much for the recipe, i discovered your blog yesterday, love it!

    • Kirbie replied: — November 16th, 2012 @ 9:16 am

      That’s so great to hear! This is one of my favorites. It’s so dangerously easy.

  20. Ellie — January 6, 2013 at 9:43 pm

    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 :D so good!! Chocolate craving satisfied!!!

    • Kirbie replied: — January 7th, 2013 @ 10:23 am

      Nice! Ice cream sounds good

  21. April — January 16, 2013 at 3:59 pm

    I just made this using dark chocolate chips and I added pecans. It was so darn yummy! Thanks so much for sharing the recipe!

  22. Rachel — January 20, 2013 at 9:11 pm

    Any idea how many calories is in this?

  23. Kate — January 21, 2013 at 9:13 am

    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 :)

    • Kirbie replied: — January 21st, 2013 @ 9:29 am

      Sorry I’ve never tried baking it. I would imagine 350F, which is standard for brownies, but I don’t know how long.

  24. Jessica @ Jessiker Bakes — March 3, 2013 at 6:39 pm

    I just want you to know you’re awesome. This is amazing. Eating it now!

    • Kirbie replied: — March 3rd, 2013 @ 9:29 pm

      Aw, glad you like it!

  25. Minh — April 7, 2013 at 12:30 pm

    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!

    • Kirbie replied: — April 8th, 2013 @ 9:50 am

      Oooh, sounds great!

  26. Stephanie — June 4, 2013 at 5:08 pm

    OMG!!!! I only had dark chocolate chips but it still ROCKED! You are so awesome.

    • Kirbie replied: — June 5th, 2013 @ 9:17 am

      I’m so glad you enjoyed it!

  27. Hannah — July 5, 2013 at 2:43 pm

    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!

    • Kirbie replied: — July 6th, 2013 @ 6:16 am

      So glad I could help!

  28. crystal — July 26, 2013 at 8:29 pm

    it taste so good

  29. crystal — July 26, 2013 at 8:33 pm

    it taste better if you add 1 teaspoon or 2 wben it finish and mix it up. YUMMMMMMMMMM!!!!!!!!!!!!!!!!!!!!!!!

    • Kirbie replied: — July 27th, 2013 @ 4:04 pm

      a tsp of what? the batter?

  30. Eileen — October 3, 2013 at 5:46 pm

    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!

    • Kirbie replied: — October 3rd, 2013 @ 8:10 pm

      It sounds like it wasn’t mixed completely. If it’s completely mixed, you won’t able to see or taste any egg.

  31. khwan — December 26, 2013 at 12:32 am

    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 ^^

    • Kirbie replied: — December 26th, 2013 @ 10:28 am

      So glad you enjoy this!

  32. Erin — February 18, 2014 at 9:39 pm

    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!!!!

    • Kirbie replied: — February 19th, 2014 @ 12:38 am

      I will have to try this with gluten free flour next time!

  33. Kayla — February 21, 2014 at 7:39 pm

    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!!!

    • Kirbie replied: — February 23rd, 2014 @ 6:18 pm

      I’m so glad you and your husband are enjoying this recipe =)

  34. Michelle — April 11, 2014 at 10:02 pm

    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.

    • Kirbie replied: — April 11th, 2014 @ 11:01 pm

      I’m glad it came out well for u!

  35. Michelle — April 11, 2014 at 10:03 pm

    I mean for a single serving

  36. Minyi — December 6, 2014 at 10:15 am

    How many tsp of chocolate (aprox.) is 2 oz? 

    • Kirbie replied: — December 7th, 2014 @ 6:30 pm

      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
