Crush or blend the Oreos so they’re like coarse sand. I use a ziplock bag and a rolling pin.
Add the melted butter and mix well.
Tip into the base of a large springform cake tin. Press down all over, flattening with a spoon or the flat base of a glass.
Bake for just 5 mins, then set aside to cool.
Make The Filling
Put the cream cheese, double cream, vanilla, sugar, eggs and flour in a bowl.
Whisk until smooth. Don't overmix as this can introduce air into the mix, which can affect the final texture and make it more likely to crack.
Set a couple of tablespoon of the white chocolate chips and chopped candy canes aside. Toss the rest in the tablespoon of flour, shake off the excess and add to the bowl. Briefly fold through.
Assemble And Bake
Pour the batter into the tin on top of the biscuit base.
Scatter the remaining chocolate chips and candy canes on top.
Bake for 45 mins to 1 hour until firm but slightly wobbly if shaken.
Transfer to a wire rack and run a knife around the inside of the tin. This is important to stop the cheesecake cracking as it cools.
Once the cheesecake is cold, cover and place in the fridge to set overnight.
When you're ready to serve, run a knife around the inside of the tin and unlock to release the sides. It should then lift onto a board cleanly.
Slice with a sharp knife to serve, wiping between cuts for a neat finish.
