Ok, the base apparently consisted of the usual crumbled cookies and butter base plus some oats.
Add some left over pumpkin purree...
Whip up some curd cheese, sugar and eggs (500g, 100g and 2)
Bake for about 40 minutes on 175°C.
And there you go :)
For the fudge, melt marshmallows with sugar and condensed milk. Pour the melted mixture over chopped chocolate and stir, stir, stir. Pour into a prepared pan and let it cool for several hours.
