Napoleon Cake (Торт Наполеон)

A classic Eastern European layered pastry dessert with impossibly thin, crisp, buttery puff pastry layers and rich, silky pastry cream. This cake is a labor of love, famous for its towering, shatter-crisp texture and delicate vanilla flavor.

Important Note:

This is a traditional, from-scratch recipe requiring time and patience. Many home cooks use simplified methods (like store-bought puff pastry), which I’ll note as a variation.

Ingredients

For the Puff Pastry Layers (Makes 12–16 layers):

• 4 cups (500g) all-purpose flour, plus extra for dusting

• 1 ¾ cups (400g) unsalted European-style butter (high-fat, cold)

• 1 cup (240ml) ice water

• 1 tbsp vodka or white vinegar (helps tenderize dough)

• 1 tsp salt

For the Pastry Cream (Zakuska):

• 6 cups (1.4L) whole milk

• 1 ½ cups (300g) granulated sugar

• 8 large egg yolks

• ½ cup (65g) cornstarch

• ¼ cup (30g) all-purpose flour

• 1 tbsp vanilla extract (or 2 tsp vanilla bean paste)

• 1 cup (225g) unsalted butter, softened at room temperature

For Assembly:

• 1–2 cups cake crumbs (from trimming baked pastry layers)

• Powdered sugar for dusting

Instructions

Part 1: Make the Puff Pastry Dough (Laminated Dough)

1. Prepare butter block:

   • Cut cold butter into ½-inch slices. Arrange them on a sheet of parchment paper to form a rough 7×7-inch square. Top with another parchment sheet.

   • Gently pound with a rolling pin until butter is pliable but still cold. Roll into a neat 8-inch square. Chill for 20 minutes.

2. Make dough:

   • In a bowl, mix flour and salt. Add ice water and vodka, mix until shaggy dough forms.

   • On a floured surface, shape into a ball, then roll into a 10-inch circle.

   • Place chilled butter square in center, fold dough edges over butter to encase completely. Seal edges.

3. Lamination (fold & roll):

   • Roll the dough into a 20×10-inch rectangle. Fold into thirds (like a letter). This is one turn.

   • Wrap and chill for 30 minutes.

   • Repeat rolling, folding, and chilling for a total of 6 turns. Always rotate dough 90° before rolling each time.

   • After final fold, wrap tightly and chill at least 2 hours or overnight.

Part 2: Bake the Pastry Layers

1. Preheat oven to 400°F (200°C). Line 3–4 baking sheets with parchment.

2. Divide chilled dough into 12–16 equal pieces. Keep unused dough chilled.

3. On a well-floured surface, roll each piece into a very thin 9–10 inch circle (thin enough to see some transparency). Use a 9-inch cake pan as a guide to trim into perfect circles. Save all trimmings.

4. Prick each circle all over with a fork to prevent puffing.

5. Bake one layer at a time for 5–7 minutes until golden brown. Watch carefully—they burn quickly.

6. Cool completely on wire racks. Repeat with all pieces.

7. Bake the trimmings on a separate sheet until golden, then crush into fine crumbs for coating.

Part 3: Make the Pastry Cream

1. Heat milk in a large saucepan until steaming (do not boil).

2. Whisk egg yolks and sugar until pale. Add cornstarch and flour, whisk until smooth.

3. Slowly pour half the hot milk into yolk mixture while whisking constantly.

4. Pour the tempered mixture back into the saucepan with remaining milk.

5. Cook over medium heat, whisking constantly, until very thick and bubbling (about 3–5 minutes).

6. Remove from heat, stir in vanilla. Transfer to a bowl, cover surface directly with plastic wrap. Cool to room temperature.

7. Once cool, beat in softened butter until completely smooth and creamy.

Part 4: Assemble the Cake

1. Place one pastry layer on a cake plate. Spread with a thin, even layer of pastry cream (about ⅓ cup).

2. Repeat stacking and spreading with all layers, ending with a pastry layer on top. Do not put cream on the top layer.

3. Cover the top and sides with remaining pastry cream.

4. Press saved pastry crumbs onto the sides and top of the cake.

5. Refrigerate for at least 12–24 hours (crucial for softening the layers).

Part 5: Serve

1. Before serving, let sit at room temperature for 30 minutes.

2. Dust generously with powdered sugar.

3. Slice with a serrated knife to preserve layers.
