Shortbread Mushrooms

Got this fantastic idea from Bake It Pretty.  As soon as I had the chance I had to make them. 
Basically you make a up simple shortbread/biscuit mix, I flavoured mine with coconut due to the fact I've had a bottle in my cupboard for ages, rolled into balls place on baking sheets then dip a beer bottle in water then cocoa and press into the balls then bake.  That's it!
