In a large mixing bowl, add the cream, sugar and vanilla extract. Use an electric whisk to whip the cream until thick.
With a spoon, spread some whip cream on the cake platter in your desired shape. This will form the base of your cake.
Take two biscuits and sandwich them together with some whipped cream. Stand them up on the platter and repeat until you have created the cake.
Use the remaining cream to cover the biscuits and mold the cake into your desired shape.
Sprinkle grated chocolate over the top of the cake and add your raspberries.
Place the cake uncovered in your fridge for a minimum of 6 hours.
