Crumble the biscuits and mix them with the soft butter. Leave them aside and prepare the cream mixture.
Put the cream cheese, sour cream, vanillas and sugar in a bowl and beat with a mixer until homogeneous.
In a glass, put a little of the biscuit mixture as a base, press lightly with your fingers, then add cream mixture and finish off with a layer of your favorite jam.
Although the cheesecake looks ready, put it in the fridge to harden before serving.
