I make this recipe often and it's delicious. Sometimes I make it with Juvela gluten free white mix and it turns out just as lovely, just a little more crumbly. The kids love it!

Utterly fantastic. Excellent recipe that worked a treat. Very nostalgic. Great taste.

Made this recipe today and although it is nice it's not true chocolate crunch, it's more like a dry sponge. I'll try my other recipe without the eggs again next time.

Made this cake this morning for a school dinners themed cake club, really simple and worked really well. Saw similar recipes online & people had said that it was too hard - I turned temp down to 160' as we have a fan over and took it out just before the 45min. It's lovely :)
