Don't leave it in the oven for too long because it can get dry and lose its moistness!
lowered the sugars as suggested by GiselleRozzell but kept same amount of cocoa powder and I used dark chocolate chunks as not a fan of white, turned out beautifully and very indulgent - 04 Jan 2014
Delicious and so easy. I also lowered sugar amounts and brownies were still lovely & sweet. Have made these numerous times now! - 21 Sep 2016
Made these today very tasty. suggest less coccoa and reduce both sugars at least by 20g, the same with butter..I added a handful of rasberys which keeps them moist. - 13 Apr 2013
