  • 3 tbsp vegetable oil or sunflower oil
  • a few drops of vanilla essence or other essence (orange or peppermint work well)
  • 2 tbsp chocolate chips, nuts, or raisins etc (optional)


  1. Add the flour, sugar and cocoa powder to the largest mug you have (to stop it overflowing in the microwave) and mix. Add the egg and mix in as much as you can, but don't worry if there's still dry mix left.

  2. Add the milk, oil and essence and mix until smooth, before adding the chocolate chips, nuts, or raisins, if using, and mixing again. Centre your mug in the middle of the microwave oven and cook on high for 1½ -2 mins, or until it has stopped rising and is firm to the touch. Don't forget to watch it rise as it cooks!

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!

This is actually a great recipe, I ended up with a very soft spongy delicious cake. However, 3 things to note. 1) Don't use a mug, use a bowl - otherwise the batter will overspill. 2) Be careful about how long you cook it - I think 4 minutes is too long. Keep a close eye on it, check it every half minute and cook only until an inserted skewer/knife comes out clean. 3) Personally I found it was a lovely mild level of sweetness, however some may find it not sweet enough - chocolate chips or a chocolate icing would help with this. Otherwise, great recipe. Fixed my chocolate craving!

I can understand why not everyone is happy with this recipe, but I think it has potential. 1. You can't just use a normal mug! Luckily I already had a sneaking suspicion this would be an issue becauce of the amount of the ingredients. So even though I hadn't read the comments before making, I used a big soup mug. So in other words a bowl with a handle lol. So unless you have one of those big soup mugs, I would say use a deep style bowl. 2. Yes this is very easy to overcook! I overcooked mine by putting it in 4 min 45 seconds. I think it still had a nice taste and lucky for me it wasn't burnt, just really dry. But I really wanted cake and this was the last of my coco powder, so I still ate it haha (sad I know). I would bet 3 minutes cook time would be more like it. Maybe even less if you know your microwave tends to cook things faster than the recommended time. So overall I say this is a nice first attempt at making a microwave cake for me. But I will certainly continue to use the large soup mug and next time I am cutting the cook time WAY back.

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.
