How to make
Beat the butter and sugar well, until you get a smooth and light cream. Add the egg yolks 1 by 1, as well as the melted and cooled chocolate. At the end, mix with the egg whites beaten to snow.
Spread the biscuits with marmalade and arrange them along the walls and bottom of the form. Pour the cream inside and put it in the freezer to freeze.
Then, invert the cake onto a plate and smear it with whipped cream or pour on melted chocolate.
