Succès — Praline Meringue Cake

The Succès is a composed gâteau built from nut meringue discs — typically almond or a combination of almond and hazelnut — sandwiched with praline buttercream, representing a pinnacle of the French meringue-based cake tradition. The meringue discs follow the dacquoise method but with a higher proportion of nut meal to meringue, yielding a denser, chewier layer that stands up to the rich buttercream filling. A standard Succès disc formula uses 150 g egg whites, 80 g caster sugar, 180 g ground almonds, 50 g icing sugar, and 15 g cornflour. The whites are whipped to medium peaks with the caster sugar, then the sifted nut-sugar-starch mixture is folded in with deliberate, broad strokes. The batter is piped in tight concentric spirals onto parchment-lined sheet pans, forming discs 22-24 cm in diameter, then dusted with icing sugar and baked at 150-160°C for 40-50 minutes until golden, firm on the surface, and slightly yielding in the centre. The filling is a crème au beurre enriched with 30-40% praline paste by weight — a coarse-ground praline delivers textural interest while a fine paste produces a smoother, more elegant cream. Assembly involves layering three discs with generous coats of praline buttercream, chilling the assembled cake for 2-4 hours to allow the buttercream to firm and the flavours to meld, then finishing the sides with toasted sliced almonds pressed into the exposed cream. The top is traditionally dusted with icing sugar and scored with a hot knife or branding iron in a crosshatch pattern. When sliced, the Succès should reveal distinct layers: the meringue chewy but not hard, the buttercream smooth and aromatic with hazelnut, the overall effect rich but not cloying. It is best served at 14-16°C, slightly below room temperature, where the buttercream is firm enough to hold its shape yet melts readily on the palate.
