Ingredients

Why this recipe works

The method of whipping heavy cream into the hazelnut pastry cream creates a diplomatic cream, which is significantly lighter and more stable than plain pastry cream. This stabilization is critical for a multi-layered cake, as it prevents the layers from sliding apart under the weight of the stack. By keeping the crepes paper-thin, the ratio of cream to crepe remains balanced, ensuring that every bite contains an equal distribution of chocolate and hazelnut flavors without feeling overly dense or difficult to slice through.

Resting the crepe batter for one hour before cooking is essential for achieving the perfect texture. This resting period allows the gluten in the flour to relax, which ensures that the crepes remain tender and pliable rather than chewy or rubbery. When cooked at a consistent heat, the crepes develop the necessary strength to support twenty layers while remaining delicate enough to cut through effortlessly. The final glaze of warm ganache seals the cake and adds a necessary richness that contrasts with the lighter filling.

Notes and substitutions

When selecting ingredients, use a high-quality hazelnut praline paste to ensure the flavor is authentic and deep. If the paste is not available, a combination of toasted, finely ground hazelnuts and a hint of vanilla can work, though the richness of the praline is preferred.

Ensure the heavy cream is very cold before whipping, as this helps achieve the necessary volume and stability. Using a dedicated crepe pan with a non-stick surface is highly recommended to ensure the crepes lift easily and maintain their thin, circular shape throughout the cooking process.

For the dark chocolate ganache, choose a chocolate with at least 60% cocoa solids to balance the sweetness of the hazelnut cream. The ganache should be warm but not hot when poured over the cake, as excessive heat might melt the cream layers between the crepes.

If the ganache is too thick, stir in a small amount of warm heavy cream until it reaches a pourable consistency. A cake stand with a rotating base can make the assembly process much easier, allowing for more even distribution of the cream across each of the twenty layers.
