Tort de biscuiți

Instructions

1. Whip the soft butter with the powdered sugar until creamy.
2. Add the cocoa, vanilla and liquid cream, then whisk until you have a thick, smooth cream.
3. Quickly dip each biscuit in the cooled coffee, without letting them fall apart.
4. Lay a layer of biscuits in the bottom of a rectangular dish, then spread a layer of cocoa cream.
5. Repeat, alternating biscuits and cream, finishing with a layer of cream.
6. Cover and refrigerate for at least 12 hours so the biscuits soak through.
7. Decorate with the grated chocolate and chopped walnuts just before serving.
