Melt the butter with 2 tablespoons of sugar, crumble the rusks and brown them briefly. Dust with a little cinnamon and chill.
Wash, halve and core the grapes. Whip the cream until stiff. Whip the layer cheese with 100 g sugar, fold in the cream. Alternately pour in the cream, grapes and rusk crumbs (several layers on top of each other).
It tastes particularly good if it is served immediately before the crumbs get too soft.
