guys, this cake is amazing!!!! I used whole chunks of chocolate and it went like molten lava cake, delish. So quick and easy as well. just a tip for everyone, i made this in a bowl rather than a mug which works better.

I switched up the recipe a bit using 2 tbsp of sf flour instead of 4. Instead of 3tbsp of caster sugar I used 1tbsp caster sugar, 1flat tbsp of stevia, and squeezed half an orange for sweetness/moisture. No milk. Chucked in a few chia seeds and brazil nuts and it was pretty good for a 2 minute cake......and less calorific.

DO NOT MAKE THIS I do not usually comment but I have signed up today to warn others that this recipe is horrible. It is bland and flavourless. There is no sweetness at all and it tastes like the cocoa powder itself. The batter was still raw some parts throughout despite using a wide mug. I highly do not recommend attempting to make this "chocolate cake" and if you do, you may want to add a few tablespoons of regular granulated sugar.

I never review things, but I signed in just to review this. I usually just trust the star rating for recipes, but this has taught me to never trust the star rating alone! This makes a lot of cake, but it is so tasteless and bland, it's just not really worth it. I'm pretty sure by "biggest mug", they mean a soup mug or other WIDE mug, as I used one of these mugs ( ) I got just before halfway through to find raw batter. When I microwaved it again for 30 seconds, it was full again, but when I had eaten about half of it I found more raw batter! I guess I now have a never ending mug of this hideous cake? End of the story: It's only worth it if you're super desperate.

Made it as I was desperate and nothing else sweet was in the house. It not good, but its definitely edible and you can eat it and it doesn't taste awful. I ommitted the oil cause I had no oil (subbed in more milk) and it was a little rubbery but I have low standards so worked for me!

Honestly amazing! It does make a decent sized mug cake and it taste delicious! Make this a lot now but a tip is if you have it use dark chocolate cocoa powder because really it tastes the same but it gives it a little more flavour and is definitely amazing

This was literally the worst thing I’ve ever made, absolutely vile. Rubbery and doesn’t taste of anything.

Firstly, you definitely need to follow the advice of using the largest mug you own - it makes a MASSIVE amount of cake - the recipe photograph makes it looks deceptively small. I’d personally say there was enough for 2. The amount of mixture can easily be split into 2 regular sized mugs and microwaved individually. It can easily be made gluten free by substituting for gluten free flour (this didn’t compromise the texture in anyway). 2 minutes was adequate cooking time for an 800w microwave. The recipe is OK, but would be nicer with ice cream, custard etc as others have said.
