Melt the butter in the microwave on short bursts on in a small pan over a medium heat until fully melted.
Blitz the biscuits in a food processor to a small crumb or in a bag with the end of a rolling pin, add the butter, and mix until it is combined well.
Tip into a 8″/20cm deep springform tin and press down firmly – chill in the refrigerator for at least an hour.
For the Cheesecake Filling
Melt the 300g of chocolate orange in a bowl over a pan of gently simmering water, stirring gently or microwave in short bursts until fully melted – leave to cool slightly whilst doing the rest.
Mix together the cream cheese and Icing sugar until thick and whip up the double cream in a separate bowl – fold the mixtures together, and then fold through the melted & cooled chocolate. If you find its quite sloppy, whisk till thick!
OR - With a stand mixer, whip the cream cheese and icing sugar until smooth. Add in the slightly cooled melted chocolate, and whip again till smooth. Pour in the double cream and continue to whip until thick. Check it occasionally and scrape down the sides until its all combined and really thick.
Pour the mix on to the biscuit base, smooth over, cover, and chill in the fridge for 5-6 hours, or preferably overnight.
For the Decoration
Whip together the double cream and Icing sugar together until its thick and you can pipe it.
Drizzle over some melted chocolate onto the cheesecake, and pipe the cream onto the cheesecake.
Add a segment per slice, and sprinkle over some sprinkles!
Notes
If it looks like your cheesecake isn’t setting, or its a but sloppy, or you’re even not sure.. try it anyway. Try to set the mix anyway! If it still doesn’t set, freeze it and have an ice cream cheesecake!
You could easily half the recipe used to make a smaller cheesecake, I prefer to make this size because it is always eaten so quickly and is so delicious! You can serve this with a splash of cream or just on its own – its utterly delicious and so easy to make!
This recipe will last covered in the fridge for 3-4 days!
If you don't want to pay for Terry's chocolate oranges as they can sometimes be a little pricey, you can easily use regular milk chocolate and add in 2tsps orange extract.
