Made another batch today, well I made them myself this time. Last time Panda made them and never even managed to get one :(
Here's the recipe:
1 packet of digestive biscuits crushed into crumbs
1 tin of condensed milk
Easy peasy, just crush your biscuits until they can't get any smaller, mix through a liberal helping of cocoa powder and then pour in the condensed milk and mix really well. It should form a sticky 'dough'.
Just make into balls and roll in the coconut and then leave in the fridge for 10 minutes or so.
