Preheat oven to 350ºF and grease an 8x8 baking dish.

Mix together the golden Oreo crumbs, butter and brown sugar until combined.

Press the crust mixture evenly into the bottom of your greased baking dish.

Bake in the oven for 8 minutes. Remove and allow to cool while you prepare the filling.

Beat creamy cheese until smooth with an electric mixer. Mix in the granulated sugar.

Beat the eggs into the mixture until combined.

Mix in the sour cream and vanilla extract.

Pour the filling into the baking dish over the cooled crust.

In a separate bowl, mix together the diced apples, flour, sugar and cinnamon until evenly coated. Sprinkle the apples over the cheesecake filling.

In a medium bowl, mix together the crumble ingredients until well combined and sand-like texture.

Evenly sprinkle the crumble mixture over the top of the apples.

Bake the dish in the oven for 40-45 minutes, or until the topping is a light golden brown and the filling is cooked through and set.

Allow the cheesecake bars to cool for 20 minutes, then refrigerate for at least 1 hour before serving. When ready to serve, slice and drizzle with caramel sauce.
