Let the forest berries thaw. Mix the quark, cream, vanilla sugar, sugar and mascarpone to a cream.
Place the sponge fingers in a flat dish and drizzle with the amaretto and espresso. Spread the wild berries on the sponge sticks, except for a few for decoration. Spread the cream over it and dust everything with cocoa and garnish with the remaining wild berries. Chill for about 1 hour.
