  • 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!

I had a go at this and it wasn't successful at all it rose fairly quickly which was good however when I got it out it was rock hard and burnt, really unhappy with that result. sadly I have to say it was awful. happy to see it worked out for some though ! :)

Amazing tasting cake but definitely makes more than 1. I used a massive mug (sports direct one) and it overflowed in that and those mugs are massive!
Tastes fabulous with custard!

This definitely makes more than one mug! I rescued most of it into a 400ml mug but my microwave needed a good clean!

Can we have the quantities in grammes (or even ounces) please.
I started using heaped tablespoons. But then I came to the liquid ingredients, so I can't use heaped tablespoons. After all, why should we use heaped tablespoons for one type of ingredient and level tablespoons for another.
I've looked up some conversion web sites, but they don't make it clear whetehr they are refering to liquid or powder ingredients.
I wonder whether this might be the problem with the person whose mug cake came out like biscuits. Unless it was a problem with the amount of baking powder (I can't get self-raising flour where I live).

Don't be fooled if it doesn't look done! I followed the directions exactly (my "extra" was a large marshmallow cut into small pieces), pulled it out after a bit under 5 minutes, and was worried cause it still looked like it had raw batter on top, but I stuck a chopstick in it and it came out clean. Cooked all the way through.

First try was burnt in the middle and had just under 4 mins in a 850 microwave. Made again but this time I divided the mixture into 3 ramekins. Cooked for 1 min. Cake tasted pretty good but a little dry.

Replaced oil with extra milk and mixed in a large cereal bowl. I find it serves more like 6! Great for a quick dessert, and lovely with custard.

Used 3 tablespoons sugar and was sweet enough

makes way more than a mug. I mixed mine in a small mixing bowl (cooked it in ramekins) and it would have filled the bowl once cooked. Didn't have any sunflower oil so used ExV oil and it worked fine. If you cook it too long it's like the sponge you get in sofas, but really it's not half bad. For a quick 5 minute pud for the kids (with some apple sauce I made earlier and a ball of ice cream), it's a good little pud.
