Preheat oven to 180°C and line a loaf tin
Using a blender, crush up the biscuits and add them to a bowl. If you don't have a blender, put them in a zip lock bag and crush them with a rolling pin
Add the coconut and butter to the biscuits and mix. Place into the lined tin and press down firmly
In the same bowl add the condensed milk, passion fruit pulp and lemon juice. Mix until combined and place on top of the base
Bake for 20 minutes or until the edges are golden. Leave to sit until it's cool enough to put in the fridge, then leave it to set for 2 hours
Slice up and enjoy - store in the fridge
