Preheat the oven to 200C/180C Fan/Gas 6. Line an 8" square baking tin.
Melt the white chocolate in the microwave in 15 second intervals, stirring in between. Set this aside whilst doing the rest
In a bowl, smash up the Bourbon biscuits (or use a food processor) until they reach a fine crumb. Stir in the melted butter and press into the baking tin. Ensure the biscuit level is even before baking for 7 minutes. Once bake, let sit on a wire rack and keep the oven on.
Make the cheesecake by whisking the cream cheese in a large bowl on high speed for about 2 minutes. Then add the sugar and whisk for 2 more minutes.
Add in the flour, vanilla extract, lemon juice and eggs and combine again.
At this stage, add in the melted (and cooled) white chocolate. Fold together with a spatula or wooden spoon, until just combined.
Pour half of the cheesecake mixture over the base. Spoon about half of the cherry mixture (juices included) over the cheesecake.
Pour over the remaining cheesecake mixture. Again, spoon the rest of the cherry mixture over the cheesecake. Swirl using a spoon for that pretty marbled effect. Bake for approx 35 minutes - until the edges are golden and the middle looks just set.
Let cool on a wire rack until room temperature, then chill in the fridge for at least 2 hours before slicing and serving!
