In your Instant Pot place the can of condensed milk in it without its can wrappings submerged in water. Cook it for 40 minutes on manual and remember to seal it.
Preheat the Airfryer to 180c.
Flour the sides and bottom of your spring form pan with your hands so that it becomes non-stick.
Crumble the digestive biscuits by giving it a hammering with a rolling pin inside a sandwich bag or inside its wrappers.
Mix the melted butter into the crumbled digestives inside the spring form pan (less washing up that way) and using your hands make sure it pushes down on the bottom.
In a mixing bowl and using a hand mixer, mix the sugar into the soft cheese until it is nice and fluffy. Add the eggs and vanilla essence and mix in with the mixer. Put to one side.
When the condensed milk is done and cooled down, open it up and pour the caramel into the bowl. Mix it in with a fork and then place the mixture into the spring form pan over the biscuit base.
Level it and make it smooth with the spatula.
Cook for 15 minutes at 180c, 10 minutes at 160c and then a last 15 minutes at 150c.
When it is done, place it in the fridge to cool for 6 hours.
When it is done drizzle over the top with a fork small amounts of melted chocolate and leftover caramel.
