Anyone know how to make chocolate concrete/crunch ???

Anyone ???

I used to have it all the time at school and the my nan used to make us a big tin full every week.
I have tried shop bought but it just doesn't taste the same.

Bumping again !

May I recommend.... the addition of glace cherries. This makes it lovely and moist.

That's it, I'm off now or I'll succumb to a cake-baking mood.
