Marbled chocolate crumble cake

I finally got round to trying one of Dan Lepard's sweet recipes.  Once again an easy to make recipe which tasted pretty good too.  Although I must admit we ate this still hot from the oven, so I have to assume it tastes as good cold (but I guess the chunks of dark chocolate wouldn't still be melted then).  This cake would make a wonderful hot pud with ice cream.  

Chocolate covered marzipan balls

As promised this is what to do with spare marzipan.  Roll it into smallish balls.  Melt some dark chocolate and then roll the balls in the chocolate until covered.  Leave on a sheet of foil in the fridge to chill and there you have the perfect quick present for someone.
