    Tried it again with milk instead of rum. It works, but definitely better with rum.

    I just made this substituting butter for vegetable oil and added a tablespoon of rum so the ingredients would blend better. It came out great!

    Have absolutely no idea how anyone made this work.

  • crazycanuck 27/02/14 02:16

    I would love to know how those who made this work did so, as I had the same result as Katyskillen, and I even added baking powder.

    This brownie was terrible in each and every way. We kept it in for the time suggested and when it came out it was the texture of soil. It was also very burnt. We had to throw it out as it it tasted rocky and bitty and was highly not enjoyable. I will not be using this recipe again... Ever. I wasted my good ingredients and I'm not satisfied.

    this is the great! i made two. one with self raising and one with plain. plain was better by far!!!

    *UPDATE* I found this recipe delicious although I changed a few things for instance.. The Vegetable Oil I changed for Dairy free Pure sunflower butter. For the Sugar/Cocoa I used Nestle Nesquik chocolate which gives a sweet tastle plus It has added Vitamin B C and D it also Has Iron and Magnesium which is great for your body. So for a delicious fluffy snack that's good for you I would recommend these alterations :) I heated this for 1 min 30 secs and it was perfect, Left it for 1 minute afterwards. *please use self raising flour or it will not rise :(

    I made this recipe and it was great. I substituted butter for the vegetable oil, melting it as a first step before adding the other ingredients. I added a dash of cinnamon to mine which was nice. I did 60 sec in 1000w microwave and it was sticky while warm and a bit hard when cold. However I think I will try with self raising flour next time and see if its a bit less stodgy. One problem was it stayed hot for a long time so my 3yo was losing interest by the time it was cold enough to eat.

    Decided to make this as a nice afternoon comfort treat. I did it for 1 minute 40 in a 850w microwave but had to stop it 20 seconds early as smelt burning! Although it was a little overdone and therefore stodgy it was still delicious and will definitely be making it again.

  • Jackie3790 06/04/13 21:52

    I made this but you forgot to put in baking soda because it dose not rise other wise I had to make it three times

    Very yummy and very fast and easy. I didn't have any cocoa powder, so used three spoons of hot chocolate powder instead of the sugar and cocoa. I also used butter instead of oil. I ate it with a large dollop of cream - perfect.

    Fabulous. Tried it for DH tonight. It took less than 5 mins from deciding I would try it to putting it on the plate. DH very pleased! Only problem was only had olive oil which apparently gave it a slightly off flavour

  • bongobec 15/11/12 11:17

    Fabulous idea, perfect for after dinner choc cravings, thanks! only took 50 sec to cook in my new 1100W microwave. Found the standard recipe came out gritty in my microwave as sugar didn't dissolve, plus was a bit too stodgy for my liking. So substituted golden syrup for sugar and SR flour for plain flour and was perfect! I just used same quantity when substituting the golden syrup but if you like things very sweet might want to use a bit more. Great also with pecans mixed through and served with vanilla ice-cream.

    oooh i could've done with this last night. will get it a go later , thank you. : )

  • Woozley 07/11/12 15:53

    Brilliant, made two ten minutes before school run, went down a treat with daughters.

  • AmberLeaf 05/11/12 13:03

    Hit the spot! I didn't have any cocoa, so I used Cadburys drinking chocolate instead, I used only 1 tbsp of sugar though. I was going to be greedy and double up on the ingredients, but really there is no need, this portion was perfect. I had mine with a dollop of ready made custard on top.

  • Allofaflumble 03/11/12 18:09

    This is going to be dangerous for me! At 1.40 in my microwave it burned but at exactly 1.00 minute it was perfect.I always have Elmlea long life cream in fridge so it was gorgeous with that poured over it.

  • CoopedUp 03/11/12 16:48

    Just tried this one: no mess; v little washing up, just enough prep involved for a very impatient mum&5yo. Lovely with dairy free icecream; A great quick afternoon boredom breaker. 9yo DD disliked it though.

  • 03/11/12 09:20

    DS made this last night, it was horrible. Sorry! texture was muddy, flavour was poor, I certainly wouldn't make it again, unless I was catering for a vegan or someone with egg & dairy allergies.

  • glub 02/11/12 21:01

    I didn't have cocoa so I tried birds' custard powder. had a few goes and i think this was the best: 2 tbsp plain flour 1 tbsp sugar 1 tbsp birds' custard powder 1 tbsp vegetable oil 2 tbsp water 2 tbsp milk microwave for 1min30 in a 700w looks awful tastes pretty good. like doughnuts strangely!

  • BeyondGoesOffWithABigBang 02/11/12 15:46

    Mmm, just made this for me, DH and DS1 (made his using tsps instead). It is yummy!!

  • MrsJamin 16/02/11 09:41

    This is simply amazing and a way of having a quick chocolate fix in the evening when you don't have any chocolate in!

  • JoyceBarnaby 03/02/11 20:24

    This is amazing and so quick!!
