3 Ingredient Nutella Brownie in a Mug (Microwave Mug Meals)

Save Recipe

From after-school snack time to anytime indulgence, my three ingredient Nutella recipe will yield you a perfect brownie in a mug.

Hi Bold Bakers!

We all know that dessert is the most important meal of the day so let’s get down to business with my Microwave Mug Nutella Brownie. If you’re a chocoholic like me, you appreciate a good chewy brownie. For a brownie this delicious, it’s incredible to learn that the recipe requires just three ingredients and takes just a minute to yield in the microwave.

How to Make a Brownie in a Mug

This easy brownie recipe is made with just a few ingredients: a bit of Nutella (store-bought or homemade nutella), a gently-whisked egg, and all-purpose flour. Like most baked goods, whisk your wet ingredients together first then add them to your dry. Once your batter is ready, your homemade brownie is ready for the microwave.

Microwaving your brownie in a mug will actually steam any liquid in your batter from the inside out rather than the outside in, meaning you’ll have as chewy of a brownie as its traditionally-baked predecessor. Cooking time given is based on my 1200W Panasonic Inverter Microwave so your timing might vary. I suggest checking it after 1 minute of baking and go from there. If your brownie is overcooked, it will dry out and harden. Your microwave brownie will be done once the top has just firmed.

This mug brownie is perfect for after-school snack time, great for sleepovers, and ready any time you want to indulge yourself. Don’t take my word for it, make it and taste for yourself. I know I’m not supposed to have favorites, but this is my favorite mug dessert and soon you’ll know why.

  1. Yana on June 10, 2018 at 4:36 am

    Dear Gemma,
    Made this with my sister with a few adjustments including a medium egg and 3tbsp of flour. Was a bit spongy but an delight. I love how you incorporated nutella (we have too much). Will be trying new recipe.
    Thank You

    • Gemma Stafford on June 11, 2018 at 5:24 am

      Hi Yana,
      Great! I am really happy to hear how you managed this recipe, well done you.
      Thank you for this kind review,
      Gemma 🙂

  2. Nanann on April 13, 2018 at 2:50 pm

    Yum! I tried this yesterday. I don’t have any suitable mugs, so I just used a small soup bowl. It turned out perfect – rich and decadent. I love that I can make small serves such as this when my grandchildren come to stay – I can give each one what they like without making a huge quantity that will go to waste.
    Thank you so much for this and all the other brilliant mug meals ideas – can’t wait to try them all

    • Gemma Stafford on April 13, 2018 at 6:23 pm

      I’m thrilled to hear that! This is actually one of my favorite mug meals.

      Gemma 🙂

  3. Esther on March 7, 2018 at 1:32 pm

    I added double of the recipe ingredients because my daughter bought extra large eggs by accident. Doubled the the time, came out FANTASTIC! Thank you! I could only eat half, it’s so.. Rich and delicious. Can’t wait to try my silicone molds for the microwave cake recipes you have. Love your website and how well you explain everything.

    • Gemma Stafford on March 8, 2018 at 3:46 am

      Hi there,
      Good news, thank you, well done to you and your daughter,
      Gemma 🙂

  4. Perry P. Perkins on February 5, 2018 at 1:19 pm

    Hey Gemma, LOVE this recipe.!

    I’m planning to demo this one tomorrow morning on AM Northwest (our local morning show), and I’d like to give you recipe credit and mention your blog, if that’s okay.

    Let me know!

    Thanks again,

      Hi Perry,

      I would really appreciate you crediting me, thanks for asking.

      • Aimée Callaghan on February 18, 2018 at 3:39 am

        Hi I made the brownies and they are amazing a bit bland but delicious and they really fill you up I personally like to add cream and raspberries

        • Gemma Stafford on February 18, 2018 at 4:06 am

          Hi Aimee,
          Great, well done you, and yes, additions help here, it is a base recipe really, that is a good point, thank you,
          Gemma 🙂

  5. Ayuki on February 2, 2018 at 1:15 am

    The brownie turned out really thick, and somehow sticky…? Did I add too much flour..?
    It tastes pretty fine tho..?

    • Ayuki on February 2, 2018 at 1:17 am

      2 tablespoons as in rounded or flat..? 😅

    • Gemma Stafford on February 2, 2018 at 2:37 am

      Hi there,
      I think you may have slightly over baked. Check it at 40 seconds, if it feels firm to the touch it is done, proceed in 10 second increments if it is not done.
      I usually say level tablespoons if this is what I mean, so not heaped, but rounded. This is actually true for most recipes, if you are requires to dd more it will say ‘heaped’.
      I hope this is of help,
      Gemma 🙂

      • Ayuki on February 2, 2018 at 7:47 pm

        Thank you so much!!
        I have another question, is it okay if I used plain flour instead of all purpose flour? 😛

        • Gemma Stafford on February 3, 2018 at 12:25 pm

          Yes sure plain flour is totally fine to use 🙂

  6. chel on January 12, 2018 at 10:21 pm

    Hi gemma!

    I really love your Nutella Mug Brownie, I kinda nailed my first mug cake and I wanted to make a bunch of these. I am wondering, can you suggest a cheaper substitute for Nutella? 🙂

    • Gemma Stafford on January 13, 2018 at 4:58 am

      Hi there,
      ( here is a recipe to make your own chocolate hazelnut spread.
      I do not know where you live, but many supermarket groups make their own version of this too, at a considerable lower price, have a look around.
      I wish you well with your baking, well done so far,
      Gemma 🙂

    Hi Gemma
    Can I make this into a molten lava brownie? If so how long do I microwave it for ?

  10. Sonia Francis Thuraisamy on November 30, 2017 at 9:31 am

    Hello Gemma,

    Thank you for this beautiful recipe. I just wanted something sweet and not overly sweet and with Nutella.
    It turned out really the way I love a bit of cake consistency. It was really decadent.
    So easy to make and didn’t wait fully to cool down and ate it as it was sooo delicious. Sorry for not taking any pictures.
    Thank you for posting beautiful recipes!!!
    Thank you for doing an awesome job.
    Sonia 😊

    • Gemma Stafford on November 30, 2017 at 7:34 pm

      Hi Sonia,

      I have made these for a dinner party and people still talk about them 🙂

      Really glad you like my recipes. Thanks for being apart of the community.

  11. Catherine on November 17, 2017 at 12:18 pm

    Hi: Is it possible to microwave more than one at the same time. I am having a dinner party and would like to be able to make more than one at a time. Also, what do you think of creating them in a glass muffin-type pan? I ‘m sure they would be smaller; how would you adjust the ingredients?

    Thanks so much for your expertise.

    • Gemma Stafford on November 18, 2017 at 9:37 am

      Hi Catherine,
      I would not bake them like this!The way microwave energy distributes really mitigates against it.
      A few things would change, the time, and the position of the pan in the oven. If there were four, centered in the oven, it could work out well for you. I cannot tell you about the timing, you will have to check that as you go. When they feel firm to the touch they are baked. I think I would test this before your party,
      Gemma 🙂

  12. Charlotte on October 29, 2017 at 3:52 am

    Hi I would love to do this recipe because it sounds and looks amazing but I only have strong brown flour. Would it still work and if so how much would I use? Thank you. 😁

    • Gemma Stafford on October 30, 2017 at 6:27 am

      Hi Charlotte,
      Well!!! not so much!
      The gluten level of strong flour will affect the texture of the bake.
      You can reduce this by blending the flour with a little cornflour/cornstarch, which has no gluten, and balances it out. ( this recipe will help you,
      Gemma 🙂

  13. Amy on October 3, 2017 at 4:26 am

    oh my god this is the best mug cake ive ever made. I’m usually really skeptical about mug cakes because they always end up too dry and bland. However I read your comment about microwaving for 40 seconds and then at 10 second intervals and in combination with this recipe it worked out perfectly! I did add a little coconut milk just to make the mixture a little smoother which worked great 🙂

    • Gemma Stafford on October 3, 2017 at 5:26 am

      Hi Amy,
      Thank you so much for this review of this recipe. This really is about understanding how a microwave oven works, and you have it figured. well done you,
      Gemma 🙂

  14. Maimoona on September 30, 2017 at 1:44 am

    I tried this recpie last minute to surprise my sister on her birthday as my oven decided to break down. It turned out so well and we both enjoyed eating every single bit of it. This recipe is perfect to calm your midnight chocolate cravings. Delicious, easy and hassle free!!!
    Thank you

    • Gemma Stafford on September 30, 2017 at 5:06 am

      I’m delighted to hear that. This is one of my favorite 🙂


  15. Samira on September 30, 2017 at 12:23 am

    Hi I only have medium eggs how much nutella and flour do i add

    • Gemma Stafford on September 30, 2017 at 4:55 am

      Medium eggs are just fine Samira 🙂

  16. Samira on September 29, 2017 at 8:35 am

    Hi what do you mean by 1/4 cup plus a table spoon. How many table spoons is it.

    • Gemma Stafford on September 30, 2017 at 5:16 am

      It’s 5 tablespoons Samira 🙂

  17. Vicky on September 19, 2017 at 7:06 pm

    Just tried this. Perfect for a quick snack to curb that sweet tooth. Reminds me of those T.V. dinner tray brownies.

    • Gemma Stafford on September 20, 2017 at 2:18 am

      Hi Vicky,
      I am really happy that you like this little recipe, I hope you try some of the others too!
      thank you for being with us,
      Gemma 🙂

  18. P.S. on September 18, 2017 at 10:14 am

    This one saved my day, I really wanted a chocolate dessert and I didn’t have enough ingredients to make a cake or something big. I tried other mug recipes on the internet before and they didn’t go well so I’m very happy that I gave yours a chance, they worked perfectly every time.

  19. Areeba on September 14, 2017 at 12:06 pm

    My brownie is spongy,it is not baking right. It is so hard to cut. What am I doing wrong?
    Please tell me

    • Gemma Stafford on September 14, 2017 at 4:18 pm

      Really? so one thing is go back over the recipe and make sure all the ingredient amounts were correct.

      Secondly, do you happen to beat the mix really hard? this is what could make it hard and spongy.

      I hope we can solve this because I haven’t heard this problem yet.

      • Areeba on September 17, 2017 at 11:13 am

        I did mix it for a long time because I just wanted it to be mixed well.
        Could it be about less heat ?

        • Gemma Stafford on September 18, 2017 at 2:07 am

          Hi Areeba,
          It could be about a shorter time! it may indeed be over-baked. This is a learning curve, and it is worth getting it right. Try again, bake at full power for 40 seconds, then check it, then in 10 second bursts until it feels firm to the touch on top. Not hard, just barely firm. Allow to stand for a minute or so to allow the heat to distribute. This should work well for you,
          Gemma 🙂

  24. Lux on August 6, 2017 at 7:58 am

    Thanks for sharing such an easy recipe!Btw, I was wondering if I could substitute the egg with banana. If so, how much should I add in? Hugs an kisses from India!

    • Gemma Stafford on August 7, 2017 at 2:38 am

      Hi lux,
      Thank you for your kind comment.
      Yes, I would choose applesauce/yogurt or flax egg, but you can try banana too. I suggest about 1/2 tablespoon for this recipe, it will not really harm the recipe, and you can adjust it if it is too strong for you,
      Gemma 🙂

      • Lux on August 7, 2017 at 6:33 am

        Thank you so much! ??

  25. Ella blare on August 4, 2017 at 1:09 pm

    This recipe is amazing but thar is glossy stuf that looks like egg white what should I do?

    • Gemma Stafford on August 5, 2017 at 2:03 am

      Hi Ella,
      I have no idea what this is. Did you bake it? Was it there after you baked it?
      Gemma 🙂

  26. Idika on August 2, 2017 at 5:42 pm

    Hi Gemma,
    Just wondering, can you make this eggless? I am vegan and I really want to try the recipe

    • Gemma Stafford on August 2, 2017 at 7:12 pm

      hum, so you can can but your end result might be a bit different. I would recommend banana or apple sauce.

      Do you have egg egg substitute chart? print it off so you can convert any recipe.

  27. Anna on July 24, 2017 at 11:52 am

    Amazing! Super quick and easy. I top mine with cookie butter ? So good!

    • Gemma Stafford on July 25, 2017 at 3:10 am

      Hi Anna,
      That is great, what a good idea, well done you,
      Gemma 🙂

  28. Haneen on June 24, 2017 at 3:14 am

    Love your videos and I really want to try this nutella brownie recipe. I just want to ask on what heating setting do you set up your microwave ?!

    • Gemma Stafford on June 25, 2017 at 1:36 am

      Hi Haneen,

      A high setting is perfect. Everyones microwave is different so just check you cake and make a call if you need more or less time to cook it 🙂

  29. HollyTheBoldBaker on June 11, 2017 at 4:27 am

    When I made it, I used all the correct measurements and cooked it on correct timing but when it came out, it was tasteless and it was very lumpy.. It looked as if the egg turned it into scrambled nutella egg..

    • Gemma Stafford on June 12, 2017 at 2:22 am

      Hi Holly,
      I think you need to go back to the recipe, take another look at it, see if you can see what went wrong. Stop the cooking a little short of the time and check if it is baked. Press oyur finger to the top of the cake, if it feels firm to the touch, it is done.
      On your second query, yes, you can chop up a semi-sweet/dark/70% ish chocolate, I do this all of the time really,
      Gemma 🙂
      Gemma 🙂

  30. Sandy Chen on May 3, 2017 at 5:46 pm

  32. Madiha on April 14, 2017 at 12:37 pm

    Hi Gemma
    Love your videos can you plz do some baking on stovetop i don’t have oven and my son wants me to do baking

    • Gemma Stafford on April 15, 2017 at 4:31 am

      This is a great suggestion Madiha!
      Where I grew up in Ireland, baking was done in a bastible pot, over a fire, in the old days.
      I never did this but it is entirely possible, and is still done this way in many places. I will add this to my list,
      Gemma 🙂

      • Madiha on April 16, 2017 at 4:42 am

        Thanks Gemma for considering my idea
        As i live in Pakistan and I tried your homemade whipping cream but after adding gelatin the milk did not set to give the desired consistency

        • Gemma Stafford on April 17, 2017 at 2:21 am

          Ah Madiha,
          i am sorry that this did not work for you. This is a set milk/milk jelly. it is useful for some things, such a cheesecakes, but is not a real cream. I am trying to come up with a better alternative, but it is difficult,
          Gemma 🙂

  33. Sufyan Majeed on March 26, 2017 at 2:38 am

    Can you make a garlic bread in a mug and a nutella stuffed ponchik in a mug which is an armenian doughnut stuffed with nutella and it is the bestseller of art gallery in LA.

    • Gemma Stafford on March 26, 2017 at 3:27 am

      Hi there,
      Thank you for this suggestion, I have added this to my list, and will be trying the Ponchik soon to see what I can do with that recipe,
      Gemma 🙂

  34. Sufyan Majeed on March 24, 2017 at 1:32 am

    Hi Gemma,
    Can you make a homemade twinkie in a mug and a japanese fluffy cheesecake in a mug and a magic cake in a mug?

    • Gemma Stafford on March 24, 2017 at 2:43 am

      Haha1 Yes, I will need to think about these, I will add them to my list,
      Gemma 🙂

  35. Sufyan Majeed on March 23, 2017 at 7:30 am

    Hi Gemma,
    Can you make a pound cake in a mug?

    • Gemma Stafford on March 25, 2017 at 4:03 am

      Hi there,
      In theory yes! A number of the mug recipes are approximately this mix. Check them out, proportions will matter greatly,
      Gemma 🙂

  36. Cassendra on February 20, 2017 at 7:34 am

    Hi Gemma!
    When I first baked this I followed the time order in your recipe box. I checked it, and the cake felt really gelatin. So I baked it for 1 more minute. Then it was too dry.
    My mom told me to add milk and it turned out delicious. Can we add milk to the rest of your three ingredient mug cake recipes?

    • Gemma Stafford on February 20, 2017 at 11:38 am

      Yes, for most of these recipes you can change the liquid, it will make it little richer.
      If oyu stand the mug cake for one minute after baking it will firm up, experiment with this too, it is part of the cooking process 🙂

      • Cassendra on February 25, 2017 at 11:23 am

        Okay thanks!
        P.S: I love you and your microwavable mug meals!

        • Gemma Stafford on February 26, 2017 at 6:17 am

          Thank you Cassendra, it is good to have you with us,
          Gemma 🙂

  37. Arvind on February 9, 2017 at 8:42 pm

    Made only one serving to try and both my 5 year old and 2 year lived it. My husband and I only got a couple of bites. Thank you for such any easy weeknight dessert for my family.

    • Gemma Stafford on February 13, 2017 at 11:59 am

      YEA! this is what I love to hear, good job you, thank oyu for letting me know,
      Gemma 🙂

  38. Audi on February 3, 2017 at 3:57 am

    I tried this today (with cake flour instead of all-purpose) & it turned out amazing! It wasn’t overly sweet, with the Nutella taste still shining through. The brownie did have more of a cake consistency, but it was soft and fluffy so I’m not complaining one bit.
    I’m super impressed – it’s really hard to find a good chocolate mug cake recipe, and this one has definitely become my favourite! It’s a quick (and delicious) fix for a chocolate craving & I highly recommend it!! Thank you xx

    • Gemma Stafford on February 3, 2017 at 10:49 am

      Hi Audi,
      That is great, I am really happy to hear that. Getting these recipes to suit what you have in your kitchen is really what it is all about, well done you,
      Gemma 🙂

  39. Prachi jain on January 25, 2017 at 10:19 pm

    In the one minute mug brownie recipe with what can i replace banana with and mention with quantity pls…

    • Gemma Stafford on January 27, 2017 at 1:56 am

      Well really I am not sure what you are trying to achieve! Is it that you do not like banana? if so it is best to choose a different recipe, there are many here on the website, the hot chocolate on may be good for you,
      Gemma 🙂
