This Jaffa Cake cheesecake layers a bourbon biscuit base, baked cheesecake filling, orange jelly and a dark chocolate ganache into one showstopping bake.
Separate the jelly into cubes and place into a heatproof jug.
Add 150ml (10 tbsp) of boiling water and stir until dissolved.
Add a further 90ml (6 tbsp) of cold water.
Pour the mixture into the 18cm (7 inch) tin and allow to cool before placing in the refrigerator to set.
Make the base
Set the oven to 180C (160C fan). Put the bourbon biscuits in a food processor and blitz to a sandy crumb. Alternatively, put them in a ziplock bag and bash them with a rolling pin.
Pour in the melted butter and mix well.
Empty the mixture into a 23cm loose-bottomed nonstick tin.
Press down with the back of a spoon until even and firm. Cook in the oven for just 5 minutes. Take it out of the oven and set it aside.
Make the filling
Put the cream cheese, cream, eggs, vanilla, flour and sugar in a large bowl and whisk gently together - you want to avoid incorporating air.
Pour the mixture on top of the biscuit base and gently level off.
Bake
Bake in the oven for 50-60 minutes until firm but slightly wobbly.
Take out the oven, and allow to cool for 5 minutes. Run a knife around the edges of the cheesecake. This will ensure it doesn’t stick, causing the cheesecake to come apart as it cools.
Allow to cool completely in the tin at room temperature, then place in the refrigerator overnight.
Decorate
The next day, put the chocolate in a heatproof bowl and melt in the microwave in 30 second bursts, stirring after each burst until just melted.
Add the cream and gently whisk until the whole mixture becomes glossy and smooth.
Retrieve the cheesecake and the jelly disc from the refrigerator.
Tip the jelly disc out of the smaller tin and lay on top of the cheesecake.
Spoon the ganache on top of the cheesecake. Spread to the edges and down the sides, leaving a cross-hatch texture on top to resemble the top of a jaffa cake.
Pop the cheesecake back in the fridge for 30 minutes for the ganache to set.
