How to make
Blend the biscuits with the milk and butter in a blender. Spread out the resulting dough along the bottom of a form to form a base.
Whip the eggs with the sugar, vanilla, cream cheese and sour cream.
Set aside a few spoonfuls of the mixture in a bowl, pour the rest in the form with the biscuit layer.
Melt the chocolate and add it to the set aside mixture, stir so they mix well.
Put the prepared chocolate mixture in an icing piping syringe or pastry bag and spray out dots, some distance apart, over the cream mixture.
Bake for 1 hour at 320°F (160 °C), then turn off the oven, open its door just a bit and leave it briefly without taking it out. Once cooled, serve.
