Wrap the exterior of a 23-cm springform pan with multiple layers of aluminum foil to prevent water seepage. Lightly grease the interior with non-stick spray.

Preheat oven to 180°C (160°C fan-assisted).

In a mixing bowl, combine graham cracker crumbs, brown sugar, and cinnamon. Add melted butter and mix until evenly moistened. Press the mixture firmly onto the base and halfway up the sides of the prepared pan. Bake for 8-10 minutes, then remove and maintain oven temperature.

In a bowl, toss thinly sliced apples with brown sugar and cinnamon. Refrigerate until needed.

In a medium bowl, blend flour, brown sugar, and cinnamon until no lumps remain. Mix in oats, then incorporate melted butter until mixture resembles damp sand and forms clumps when squeezed. Set aside.

Using a large bowl and electric mixer, beat cream cheese, granulated sugar, and brown sugar on medium speed until smooth. Scrape down the bowl as needed. Add cornstarch and cinnamon, blending evenly. Mix in sour cream and vanilla extract, scraping sides for uniform texture. Add eggs one at a time, mixing only until just combined after each addition.

Pour cheesecake batter over baked crust and smooth the surface. Arrange apple slices in an even layer on top, avoiding any excess liquid. Sprinkle the crumble mixture evenly over the apples.
08 -
Place the foil-wrapped springform pan into a large, deep roasting pan. Pour boiling water into the roasting pan to reach about 2.5 cm up the sides of the springform pan.
09 -
Transfer to oven and bake for 50–60 minutes, or until the edges are set with a slight wobble in the center when gently nudged.
10 -
Remove the roasting pan from the oven. Allow cheesecake to cool to room temperature in the water bath.
11 -
Extract the springform pan from the roasting pan. Cover and refrigerate for at least 6 hours, preferably overnight, to set fully.
12 -
Run a sharp knife around the pan edge before removing the springform rim. Slice using a thin, sharp knife, making sure to cut through the crust. Optionally, drizzle each slice with salted caramel sauce before serving.
