Microwave Mug Cakes – #1 Dark Chocolate

I love the concept of a microwave mug cake – stir a few pantry ingredients in a mug, zap in the microwave for a minute and then ta da! (Nearly) instant pudding for one! It was a lot of fun thinking of different flavours of mug cakes and of course, taste testing each of them.

Just quickly, how cute are these mugs?! I picked them up from Woolworths the other day, down from $4 to $2 each – bargain!

The first mug cake in this series is the classic dark chocolate mug cake. I regularly make a giant dark chocolate pudding in the cooler months, and there is nothing more comforting on a wintery night. But it’s 8 servings and let’s be honest I don’t need ALL those calories. So a single serving basic choc pudding is perfect! I also love this recipe as I can get my chocolate fix even when I don’t have chocolate in the house – cocoa powder solves that problem!


♥ Choc Peanut Butter Mug Cake – drop a tablespoon of peanut butter into the middle of the mug before cooking for a delicious peanutty surprise.

♥ Double Choc Mug Cake – if you have cooking chocolate buttons lying around, put a few on top of your pudding mixture. They will sink as it cooks, giving you a wonderful molten chocolate filling.

♥ Vegan Mug Cake – Substitute butter for vegetable oil, milk for soy or almond milk and omit the egg. Serve with vegan icecream or it’s delicious with just a dusting of icing sugar!

♥ Bounty Coconut Mug Cake – Add in a tablespoon of shredded or desiccated coconut and mix into the batter. Stick a fun size Bounty, or 2 squares of Lindt Coconut, into the middle of the batter for an extra coconut filling!

    I LOVE this recipe!!! And it’s not dry like the other microwave mug cakes I’ve had. Very well done. And I’m looking forward to the other recipes.

      Yes I love how moist it is Tammi! Microwaving it for 1 minute on medium makes it cooked but still gooey on the inside… heaven!

    Awesome recipe series Swah! I can’t wait to see the other flavours. And those are super adorable mugs!! I’ve actually never made a mug cake before because they’re so dangerous haha but your recipe sounds too tempting not to make. I especially love all your delicious sounding variations!! Hmm I wonder if you could replace the peanut butter with a spoonful of dulce du leche for a caramelly surprise? :D

    • Reply Swah July 30, 2013 at 1:48 pm

      I have indeed put a tablespoon of dulce de leche inside a chocolate mug cake once and can confirm it was AMAZING! Stay tuned for my salted caramel mug cake, you will love it! x

        • Reply Swah March 8, 2021 at 10:46 am

          Hey Gracie! Might be overcooking it/cooking it too high. Every microwave is different so it’s hard to tell from here, but I would suggest trying to cook it on a lower temp (you may need to cook it for an extra 10 seconds) and see how that goes!

    Also, I put some raspberries in there towards the end with the choc chips, i may never eat another dessert again

    Hello! Loving your mugs and the cakes in them.

    Very dull question, sorry in advance.

    What wattage microwave are you using? Mine’s 800 watts, so 1 min on medium = raw. Just wondering so I can puzzle it out.

    • Reply Swah November 30, 2014 at 12:07 pm

      Hello! My microwave is 1000 watts, so I guess that’s why mine cooked quicker. Perhaps like 1 1/2 mins and let me know how it goes? And It’s ok if it’s still a little gooey in the middle :)

  • Reply Marubi September 11, 2015 at 5:08 am

    I’m sad to say this was a failure. I really love your banana mug cake, so I figured I’d give this one a try too. I used the same mug and microwave as for the banana version, and I followed the recipe exactly, but I ended up throwing most of it away :( The taste was kind of bitter and egg-y, the consistency was all weird – parts of it were overcooked while parts were gooey. And I don’t mean gooey middle, I mean random parts, though I made sure I mixed it all well. So I don’t know what went wrong.
    Maybe I should just stick to the banana one, I know that one turns amazing every time :)

    • Reply Swah September 18, 2015 at 2:28 pm

      Oh that’s such a shame Marubi!! I’ve made the dark choc version like a billion times (it’s my favourite out of the mug cake recipes) and I am trying to figure out what went wrong. Definitely the size of eggs can effect how eggy the mug cake tastes, if your eggs are quite large perhaps try and add only 2/3 of the whisked egg? And as for the consistency, apart from mixing the batter well, does your turntable in your microwave rotate? I am wondering if the heat wasn’t being distributed properly…

  • Reply Hanna November 22, 2015 at 10:02 am

    Hello! I just wanted to say thank you for this awesome recipe! I’ve tried many, many mug cakes before and this one turned out the best (aka, it was actually edible and quite tasty). You’re the bomb! xx
