Six thin sponge discs are baked separately at high heat for 6-8 minutes each. Five are layered with a French-style chocolate buttercream made from a hot sugar syrup whipped into yolks then enriched with butter and melted dark chocolate. The sixth disc gets glazed with hard caramel while still warm, marked into twelve wedges before it sets, and crowns the cake. Sides masked with more buttercream and dusted with toasted chopped hazelnuts.
Five thin discs of almond-meringue (a French dacquoise) bake low and slow. They sandwich with a cognac and vanilla French-style buttercream (a pâte à bombe enriched with butter). The top is sealed with a thin layer of buttercream then iced with white fondant; melted dark chocolate is piped in concentric circles into the wet fondant and pulled into a spider-web with a skewer. Sides masked with toasted flaked almonds.
Three thin sponges bake side by side or in batches: one vanilla, one cocoa, one walnut. Each is moistened with a warm rum-citrus syrup and layered in a deep dish with raisins, walnuts and a vanilla pastry-cream-style filling. The whole thing chills overnight so the layers meld. Served by scooping (galuska means "dumpling", referring to the soft scoops), drowned in warm chocolate sauce and crowned with cold whipped cream.
