Either add your biscuits to a large bowl and break up into crumbs with a rolling pin, or pop in a blender and blitz for a few seconds.
Then, to the biscuit crumbs, add the cocoa powder, coconut, condensed milk, brandy and melted butter and mix to combine.
The mixture will be very sticky but should come together and be pliable.
Chill in the fridge for 30mins to allow the mixture to set a little - this makes in easier to handle
Using a teaspoon take a walnut-sized lump of mixture and roll into a ball in your hands - you will get messy, it's part of the fun!
Pour your Vermicelli into a bowl before you start to make your truffles.
Roll each ball in the vermicelli and place onto a plate or into a Tupperware container.
Repeat until you've used up all the mixture, this should make approximately 16 bite-sized truffles.
Pop the Tupperware into the fridge and chill.
These will keep for up to two weeks in the fridge.
