Microwave Mug Cakes – #2 Salted Caramel

This is the second recipe in my Microwave Mug Cake series (you can find #1 Dark Chocolate here) and of course I had to chose my favourite flavour of the moment, salted caramel! The brown sugar in this mug cake gives it a rich and caramelised flavour and you are treated to a delicious surprise of salted caramel in the middle.

I have provided several options for the caramel filling including salted caramel sauce, dulce de leche and Nestle caramel baking bits. The whole point of this recipe is to be simple and quick, so make use of whatever you have in the pantry!

Here is my recipe to make your own Dulce de Leche and here for my recipe for Salted Caramel Sauce. For a super quick option, throw in a tablespoon of Nestle caramel chips before you microwave for an instant caramel hit.

  • 3 tbsp butter melted (or flavourless oil)
  • 1 egg lightly beaten
  • 3 tbsp milk
  • 4 tbsp plain flour
  • 3 tbsp brown sugar
  • ½ tsp baking powder
  • 1/2 tsp sea salt
  • 2 tbsp salted caramel/dulce de leche see below for recipes


  • Put butter into mug and microwave for 10 seconds to melt.
  • Add in egg and milk and lightly beat with a fork until combined.
  • Add dry ingredients into mug and beat with your fork until mixed through.
  • Add a tablespoon of salted caramel/dulce de leche to the top of the mixture, this will sink as it cooks giving you a gooey caramel surprise.
  • Place mug in the microwave and cook for 1 minute on medium heat.
  • The pudding should be risen and still slightly gooey in the middle. If still undercooked for your liking, cook it further in 10 second bursts in the microwave.
  • Drizzle the top with the second tablespoon of salted caramel/dulce de leche.
  • Enjoy!

This mug cake is a super easy solution for a quick sugar hit, with the right balance of salty and sweet. Feel free to add a dollop of whipped cream or ice cream on top but I love it just the way it is!

    My teenage son has recently discovered salted caramel and has developed such a passion for it that he cooks batches himself and is now hoping to sell them to friends.

    My question is, would you consider providing permission to print your salted caramel mug cake recipe (appropriately credited with your website) for him to include as a purchase incentive?

    Many thanks,

    Ingrid and Caleb

    Oh Yum – my daughters and I loved this… we didn’t have the time (desperate need for some desert) to make the caramel so replaced it with choclate chips so it became a salted caramel choc chip mudcake pudding.

    I really din’t like this recipe and even though things usually work out for me this one really didn’t. when i first pulled it out i thought it was fully done because I put it in for one minute. Then i lift the top part up and the whole bottom as all the way underdone. I put it in for another thirty seconds and when i pulled it out nothing happened. so i got really frustrated and just put the part that was cooked in another mug and put the completely uncooked part of the cake back in. it took about 45 seconds for it to cook and when i took it out it smelled completely like egg. i didn’t eat any of it because i was afraid it was going to taste like straight up scrambled egg. right now i would give it one star out of five but i would try again and see how i like it and hopefully not use as much egg. I guess this is a work in progress with me.

    • Reply Swah June 1, 2015 at 10:58 am

      Oh no Trin I am sorry to hear it didn’t work out for you!! As every microwave is different there’s chance you could try putting the microwave on a lower temperature for longer (so the mug cake cooks through more evenly). As for the eggy smell, that’s puzzling! If you are using quite large eggs, possibly consider breaking the egg into a separate bowl/cup, whisking it and adding only 1/2 the contents of the eggs to the mug cake mixture?

  • Reply Talia October 28, 2015 at 1:20 pm

    This is a super tasty cake — however, I don’t think it should be called a mug cake. It’s just a microwave cake. I used the largest mug I owned and it still overflowed and made a huge cooked-on mess in the microwave. It needs to be made in a bowl. The portion that actually stayed in the cup was great, though, and I’ll be making this often.

    • Reply Swah November 2, 2015 at 3:48 pm

      Oh no I am sorry to hear it made such a mess! I must have a very large mug as it manages to contain itself in mine, but I am glad you can enjoy it from a bowl as well :)

  • Reply Mayli December 6, 2015 at 12:40 pm

    Hey swah, i can taste egg in mine and it tasted a bit hard and rubbery not soft and spongy. but it was dlicious, i put extra caramel and cream on it !

    • Reply Swah December 7, 2015 at 9:27 am

      Hi Mayli! Oh the addition of caramel and cream sounds divine! To avoid it turning rubbery, I would suggest cooking it slightly less, or on a lower temperature. Sometimes overcooking the mug cake can turn it harder. As for the eggy taste, perhaps cracking the egg separately and then whisking and adding over 3/4 of it into the batter? Eggs vary in size and when the portion is so small, you can really taste it!

    I found this recipe while looking for an alternative to chocolate mug cake (because all I have at home right now is sweetened cocoa powder, which is unusable for these recipes), when I saw “salted caramel” I knew I had to try it, I love salted caramel way too much. Oh my lord, this is enlightenment in a mug! I totally forgot to add the milk but somehow it still turned out fine? I’m kind of afraid I’ll get so addicted i’ll make 3 of these every day..
