Decadent Twenty-Layer Hazelnut Chocolate Crepe Cake Tips, FAQ & printable recipe

Tips for success

To ensure perfectly round crepes every time, use a ladle to pour the batter into the center of the pan and swirl it immediately in a circular motion until the bottom is covered. If the batter does not spread easily, the pan may be too hot, or you may be using too much batter. Practice with the first crepe, which is often considered the test run, before aiming for the perfection required for the final twenty layers of the cake.

When stacking the crepes, start by placing a small dab of cream on the center of the serving plate before placing the first crepe; this prevents the cake from sliding around on the plate. Use an offset spatula to spread the cream, starting from the center and working toward the edges. Keep the cream layer slightly thinner near the very edge of the crepe to prevent it from squeezing out too much when the next layer is added on top.

Variations

• Classic Vanilla Bean: Replace the hazelnut praline paste with pure vanilla bean paste for a more traditional French crepe cake flavor. This version is lighter and pairs beautifully with fresh berries.
• Espresso Mocha: Add two teaspoons of instant espresso powder to the cocoa crepe batter and the pastry cream. This creates a deeper, more mature flavor profile perfect for coffee lovers.

Storage and make-ahead

Fridge

Store in the refrigerator for up to 3 days, covered tightly to prevent the crepes from drying out or absorbing other food odors.

Keep the cake covered in the refrigerator to prevent it from absorbing other odors. Because of the dairy content in the cream and ganache, it is important to maintain a consistent refrigerator temperature.

The cake is best enjoyed within two days of assembly. If you need to store it longer, wrap it tightly in plastic wrap to maintain moisture, but be aware that the crepe layers may soften slightly over time, affecting the overall texture of the dessert.

You can prepare the crepes and the pastry cream one day in advance. Store the crepes in an airtight container at room temperature if used within 24 hours, or in the refrigerator for longer periods.

Keep the pastry cream in the refrigerator until you are ready to whip the heavy cream and assemble. Avoid assembling the full cake more than a few hours before serving to ensure the crepes remain fresh and the structure stays firm, as the cream will naturally hydrate the crepes over time.

Serving ideas

Serve the cake chilled directly from the refrigerator for the best structural stability. Use a sharp, thin-bladed knife to cut through the layers. For perfectly clean slices, dip the knife in hot water and wipe it clean between every cut.

This technique warms the ganache slightly, allowing the blade to glide through the delicate layers of crepe and cream without dragging or smearing, resulting in a beautiful presentation that showcases the twenty individual layers of the dessert.

Pair each slice with a small spoonful of fresh, unsweetened whipped cream or a few toasted, crushed hazelnuts on the side to complement the texture of the crepe cake. The contrast between the cold, creamy interior and the slightly firmer crepe layers creates a sophisticated dessert experience.

Serve on small, chilled dessert plates to maintain the temperature of the cake as long as possible. This dish pairs exceptionally well with a cup of strong black coffee or a light, unsweetened tea to balance the richness.

Decadent Twenty-Layer Hazelnut Chocolate Crepe Cake

Prep 1 h 20 minCook 20 minRest 1 hTotal 2 h 40 minServes 12

Ingredients

• 2 cups cocoa crepe batter, prepared and rested
• 2 cups hazelnut praline pastry cream
• 1 cup heavy cream, whipped to stiff peaks
• 3/4 cup dark chocolate ganache, warmed

Instructions

1. Heat a crepe pan over medium heat to 360°F (182°C). Pour a thin layer of the cocoa crepe batter into the pan, swirling to cover the bottom evenly. Cook for 45 seconds until the edges are set and dry. Carefully flip and cook briefly. Repeat until twenty crepes are finished, allowing them to cool completely on a wire rack to prevent sticking.
2. In a large chilled mixing bowl, whip the heavy cream until it reaches stiff peaks. Gently fold the whipped cream into the hazelnut praline pastry cream until fully incorporated and smooth. The resulting diplomatic cream should be airy and light, providing the structure needed for the cake layers to stay firm once stacked.
3. Place one cocoa crepe on a serving plate. Spread a thin, even layer of the hazelnut diplomatic cream over the surface. Repeat this process, stacking all twenty crepes. Once the stack is complete, pour the warm dark chocolate ganache over the top, letting it drip slightly down the sides. Chill for at least one hour before slicing to ensure clean, sharp layers.
