Pour the 33% whipping cream into a bowl.
Add sugar.
Add the teaspoon of vanilla essence.
Beat the mixture with a mixer on high speed for about 4 to 5 minutes, until the cream becomes thick and holds soft to medium peaks.
Pour the milk into a shallow dish and quickly soak the ladyfingers in it, one by one, without letting them fall apart.
Arrange the soaked ladyfingers in a single layer in a rectangular baking tray or dish.
Spread half of the whipped cream evenly over the first layer of ladyfingers.
Dip the remaining ladyfingers in milk and add a second layer over the cream.
Spread the rest of the whipped cream on top and smooth the surface with a spatula or knife.
Generously sprinkle cocoa powder over the top of the cake for decoration. If you like, you can also add grated chocolate, fruit, or other toppings.
Cover the cake with plastic wrap and refrigerate it for 5 to 6 hours, or until the layers are well set and the biscuits are soft.
Slice the ladyfinger cream cake and serve chilled. Enjoy.
