A bag of cookies PAN DI STELLE (available at the store)
a jar of 750 gr of NUTELLA
Half gallon of whip cream
half gallon of milk (your choice of fat)
a cup of espresso
Soak for few seconds each cookie in the milk mixed with coffee and form a first layer of cookies on a round shallow tray. Try to fill the holes with some of the cookie's crumbs , when the first layer is ready, cover it with a layer of Nutella chocolate (this operation will be easier if you heated the Nutella a little bit in the microwave or left the jar few minutes in hot water).
On top of the Nutella add a layer of whip cream that has to be cold and whipped stiff.
Proceed repeating the same process until you made it three layers.
For top layer smooth the whip cream and cover with cocoa powder.
Put the cake in the fridge for at least one hour before serving.
