Preheat the oven to 160˚C.
Crush up biscuits and add oil until it forms the texture of wet sand.
Pour the biscuit base into a lined spring form tin and press down until it's nice and compact. Set in the fridge until needed.
Beat together your cream cheese and sugar until smooth. You want to make sure there are no lumps of cream cheese remaining as they won't break down once you add more liquid to the batter.
Add your eggs and mix until thoroughly combined, followed by the yoghurt and white chocolate, adding each one after the other to make sure the mix is fully emulsified.
Finally, mix in your passionfruit pulp then pour the mixture into the prepared cake tin.
Bake the cheesecake for around 45 minutes until just golden on top and still with a slight wobble in the centre.
Set it in the fridge for at least 5 hours, but preferably overnight.
