The chocolate bourbon

Here is chapter one in the cannon of classic biscuits...the chocolate bourbon.  Much more chocolately and  satisfying than the shop version.  Pretty easy to make and with a chocolate buttercream icing in the centre, it makes the biscuit something more of a treat too.  It's more squeezey to eat, but worth making again.  Little brother chose the home-made one over the shop one when offered both- clever boy.

I'm sure you can play around with the flavours too, and go all spicy and cinnamony, should you be so inclined.
