A deliciously thick cookie crust topped with two layers of creamy cheesecake (plain and pumpkin), and finished off with a crunchy cinnamon-spiced streusel. These are the ULTIMATE bars for autumn/fall!
Preheat the oven to 180C/350F/Gas 4. Line a 9x13-inch cake pan with parchment paper and set aside.
Stir together the biscuit crumbs and sugar. Add the melted butter and mix until all the crumbs are moist.
Press evenly into the prepared pan and bake for 10 minutes. Set aside to cool as you prepare the filling.
For the Cheesecake
In a large bowl, mix together the cream cheese and sugar until combined.
Add the flour, eggs, egg yolk, vanilla, and yogurt, and mix until smooth and combined.
Pour half of the cheesecake mixture over the crust and spread out evenly. Freeze for 2 hours.
Preheat the oven to 170C/325F/Gas 3.
Add the pumpkin puree and spices to the remaining mixture, and whisk until combined.
Spoon over the frozen cheesecake layer and spread out evenly.
Bake for 30 minutes.
For the Streusel
In a medium bowl, whisk together the flour, oats, sugar, and cinnamon.
Add the butter and rub in until the mixture resembles coarse crumbs.
Sprinkle evenly over the cheesecake layer and bake for a further 45 minutes, or until set and the topping is golden brown.
Allow to cool completely in the pan on a wire rack, then refrigerate overnight before slicing.
