Clean and wash the strawberries, then cut them thinly. Cut the roll into thin slices.
Put foil in a bowl and smear it with butter. Cover the bottom and sides of the bowl with slices of the roll.
Leave the ice cream to soften at room temperature and mix it with the strawberries and hazelnuts. Distribute it into the bowl.
Put rolls on top of the ice cream. Cover the bowl with foil and freeze it for 4 hours. Serve in plates and remove the foil.
