Method:

Crush the Marie biscuits.
Once the biscuits are crushed, transfer them to a mixing bowl. Add the cocoa powder. Mix well until the biscuits & cocoa are combined.
Pour in the condensed milk and Super M.
Mix until combined. The mixture should be a bit sticky. To a separate bowl, add the desiccated coconut.
Thereafter begin spooning off small amounts of the mixture.
Roll them in the palm of your hands to form a ball & dunk the ball into the bowl of desiccated coconut, coating it throughout.
Pop them into the refrigerator for 30 minutes.
