Lollycake:

1 packet of crushed biscuits
1/2 can condensed milk
100g butter
1 packet of fruit puff lollies/eskimos cut into pieces

Melt butter, add condensed milk, add biscuits and lollies. Form into a log and roll in coconut. Let set and cut into slices. Alternatively can be made into balls.
Fruit puffs and eskimos can be hard to find though. Any shop selling NZ stuff will have them I have made it with marshmallows but they can go a bit gooey.
