I was browsing the Lowcarbmegastore which I use for tortillas and pitta breads, and in their sale section they were selling these for 99p as they are past their best before date. I don’t normally use cake mixes but this was so easy I might be a convert. I made it while my main course was cooking and it was surprisingly good: moist, very chocolatey and not too sweet. 1.75g carbs in a portion.
