This is so delicious that when I made it, the entire office descended like locusts and scoffed it before I could finish the video. Luckily, one slice remained.
Time to get the food processor out! Give the biscuits a blitz and add the butter - all going well, the mixture will now have the consistency of fine sand.
Line a 20cm tin and press the mixture evenly into it and up the sides.
Beat all the ingredients for the filling together and set aside.
Preheat the oven to 160°C. Peel, core and segment the apples then toss them with the sugar. Bake until softened, roughly 30 mins.
Rub all the ingredients for the crumble together. Pour the cheesecake mixture into the prepared tin, top with the apples then the crumble.
Bake for 1 hour 25 mins until golden brown with a bit of a wobble.
Leave in the oven with the oven off until cooled down.
Eat the next day.
