For the Choux Pastry:
- 1 cup water
- 100g (7 tbsp) unsalted butter
- Pinch of salt
- 1 cup all-purpose flour (or gluten-free flour blend for variation)
- 4 large eggs
- 2 tbsp sugar
For the Vanilla Custard Filling:
- 2 cups milk
- 1 tsp vanilla extract (or real vanilla seeds)
- 4 egg yolks
- 3/4 cup sugar
- 4 tbsp cornstarch
- Prepare the Choux Pastry Dough: Combine water, butter, and a pinch of salt in a saucepan and bring to a gentle boil. Remove from heat immediately and stir in the flour all at once, mixing quickly until the dough forms a ball and pulls away from the sides. Let cool slightly before incorporating eggs one at a time, beating well after each addition to achieve a smooth, glossy dough perfect for piping.
- Bake the Pastry Layers: Preheat your oven to 375°F (190°C). Divide the dough evenly onto two parchment-lined baking sheets, spreading it into roughly equal rectangles. Bake each layer until golden brown and puffy, about 30 minutes. Keep the oven door closed to prevent deflating. Once baked, allow the layers to cool completely on wire racks.
- Make the Vanilla Custard Filling: In a saucepan, gently heat the milk and add vanilla extract. In a separate bowl, whisk together sugar, cornstarch, and egg yolks until pale and smooth. Slowly pour the warm milk into the egg mixture, whisking constantly to temper the eggs, then return the mixture to the saucepan. Cook over low heat, stirring continuously until the custard thickens to a rich, pudding-like consistency. Remove from heat and let cool slightly.
- Assemble the Karpatka Cake: Once the pastry layers are cooled, spread a generous layer of the warm custard on one piece and top it with the second pastry layer. Let the assembled cake chill in the fridge for at least two hours, allowing the custard to set fully. Before serving, dust with powdered sugar for a beautiful finishing touch.
Notes
- Avoid adding eggs too quickly to the dough to keep it from becoming too runny.
- Do not open the oven door during baking to maintain the pastry’s puffiness.
- Let the custard cool properly before spreading to prevent melting the pastry.
- Use fresh vanilla extract or vanilla seeds for enhanced custard flavor.
- Slice with a serrated knife to maintain the integrity of the cake layers.
