    This is probably the yummiest chocolate cake recipe I've ever tried. I did find however that the butter/water/cocoa mixture that you add to the other ingredients was just too much and if I'd added it all the cake wouldn't have set. I used maybe 3/4 of that liquid for the cake batter, and added powdered sugar to the rest which made an amazing fudgy icing. I did not make the icing recipe provided here. I baked the cake in an average square pan and it took about 40 mins. Delicious cake but I do think the water measurement is inaccurate. I will definitely make again though. - 15 Aug 2016
