How to make
Make the instant coffee by pouring hot water into it and and then dip the biscuits in it 1 by 1.
Make the cream by beating the softened butter with the sugar into foam and gradually adding the eggs 1 by 1, with the cognac at the end.
Arrange a layer of biscuits in a tray, then a layer of cream. Finish off with cream and put the tray in the fridge.
