  • Microwave mug cake
  • 4 tbsp self raising (SR) flour4 tbsp caster sugar
  • 2 tbsp cocoa powder
  • 1 medium egg
  • 3 tbsp milk
  • 3 tbsp vegetable/sunflower oil
  • A few drops vanilla or other essence (orange, peppermint etc)
  • 2 tbsp chocolate chips/nuts/raisins etc (optional)


    1. Use the largest mug you have to avoid it overflowing in the microwave!
    2. Add the flour, sugar and cocoa powder to the mug and mix.
    3. Add the egg to the mixture. Mix in as much as you can but don't worry if there's still dry mix left.
    4. Add all the other ingredients apart from the chocolate chips etc (if you are adding) and mix until smooth. Add the chocolate chips and/or the nuts/raisins and mix well.
    5. Centre your mug in the middle of the microwave oven and cook on high for 4-5 mins, or until it has stopped rising and is firm to the touch. Watch it rise as it cooks!

Fitted fine into a big mug. I only used 3tbsp of sugar but then put frosting on the top so plenty sweet enough. Like everyone else said, the cooking time is wrong. I cooked mine for 4 minutes and far too long. I will try 2.5 next time. I'll also try replacing the cocoa for flour next time and make a vanilla cake. Perfect with ice cream.

First time as a midnight craving, didn't have caster sugar or self raising; so I substituted those for granulated sugar and plain flour. I used unsweetened cocoa powder but my cake turned out dry and from other comment this is normal? Next time I will definitely add more sugar, cake too bitter for my sweet teeth and unfortunately didn't eat it. Over flown in the microwave too, meh.

Wasn't until my husband had eaten the Microwave Mug Cake with custard for his dessert, did I realise I forgot to put the oil in. Not only was it very tasty it was also fat free !!!!

Don't leave it in the oven for as long as it says to. Also i found that you need to reduce everything by 1/3.

... and actually, while you are at it, you could simply adjust the recipe as posted to quantities to fit a mug... since everyone seems to have found it WAY too much (probably reduce by a third... oh, but then you have a problem with the single egg. Dang!). I started with three small (3 in/7.5 cm diam) ramekins instead of a mug and it made three modest-sized portions in those. It IS a little short on sweetness, but the sponge is good.

It would help if someone could edit the first line of the ingredients so the flour and sugar are not irritatingly concatenated like this.

This was quick and easy, but it only required about 2 minutes in a standard type microwave. I stopped it after about 2 .5 minutes when I saw it wasn't rising any more. Next time I will try about 2 mins but stop just after it stops rising.

Loved this! Made two massive mugs in 3 mins in microwave! A little too dry - should've grabbed some cream or custard for the centre but was sweet and tasty.

Great recipe it's better when you follow it correctly and you can do it wheat free!

so so tasty! easy and quick!!! I could say that the recipe could serve 1 to 3! I used a bowl and changed the recipe a little bit! I put 4 tbsp milk and only 2 sunflower oil and put it in the microwave for 3 min only! it came out DELICIOUS!!! I imagine that if I use 2 mugs instead of a bowl it will come out nice too but it might need less min in the microwave! I will try it and let you know!!!! WELL DONE!
