Step 1

Heat the oven to 170C/fan 150C/gas 31/To make the base, mix the butter and biscuits until they looks like damp breadcrumbs. Butter and line the base of a 22cm springform tin, pack the biscuit mixture into the base and chill.

Step 2

For the filling, mix the cheese, cream, dulce de leche and eggs to a smooth paste. Put this mix in the tin with the biscuit base and cook for 45 minutes until it is set, but still has a slight wobble. Cool to room temperature, then chill until ready to serve (the top might crack but will be covered up, so don’t worry). Spread more dulce de leche on top.
