FOR THE APPLE FILLING: Combine the apples, sugar and cinnamon and mix together. Cook the mixture in a saucepan over a medium heat for 5 minutes, until the apples are soft but are still keeping their shape. Leave to cool slightly and then spread over the biscuit base, leaving a small gap around the edge.

FOR THE CREAM FILLING: Whisk the cream until thick with soft peaks, add the cream cheese, mascarpone, sugar and eggs, whisk and until fully combine and then pour over the base.

FOR THE CRUMBLE: Rub the butter into the flour until the mix resembles breadcrumbs, then mix through the sugar, oats, and nuts. Spread on a lined baking sheet and bake at 170 fan for 8 minutes.

Run a thin knife around the edge of the cheese cake, then open the spring and remove the outer ring. Using a large knife run the blade between the base and the cake tin to loosen and then transfer to a serving dish. Top with lots of crumble and drizzle over homemade or bought salted caramel!
