Ingredients
Scale
Choux Pastry
- 1 cup water
- 100 g unsalted butter
- 1 pinch salt
- 1 cup all-purpose flour (or gluten-free flour blend for gluten-free version)
- 4 large eggs
- 2 tbsp sugar
Custard Filling
- 500 ml milk
- 4 large egg yolks
- 3 tbsp sugar
- 3 tbsp cornstarch
- 1 tsp vanilla extract
- 100 g unsalted butter, softened
Instructions
- Prepare the Choux Pastry: In a pot, bring water, butter, and a pinch of salt to a boil. Remove from heat and stir in flour all at once, mixing vigorously until the dough forms a smooth ball and pulls away from the sides. Let it cool slightly before incorporating eggs one at a time, stirring well after each addition until the dough becomes glossy and smooth.
- Bake the Pastry Layers: Divide the dough into two equal parts and spread each onto parchment-lined baking sheets, shaping into two roughly rectangular layers about 1/2 inch thick. Bake in a preheated oven at 200°C (392°F) for 25–30 minutes until puffed up and golden brown with a cratered surface. Let cool completely on a wire rack.
- Make the Creamy Custard Filling: Whisk egg yolks with sugar and cornstarch until smooth. In a saucepan, warm milk with vanilla extract, then gradually pour it into the egg mixture while whisking continuously. Return to stove and cook on low heat, stirring constantly until thickened and smooth. Let cool slightly, then beat in softened butter until well combined and creamy.
- Assemble the Karpatka Cake: Place one choux pastry layer on a serving plate. Spread the creamy custard evenly over it. Carefully top with the second pastry layer, pressing gently to avoid breaking the pastry. Dust the top with powdered sugar for a finishing touch.
Notes
- Let the choux dough cool before adding eggs to prevent scrambling and ensure smooth dough.
- Start baking at a high temperature to create steam for puffing, then lower if needed to bake through without burning.
- Whisk custard continuously while cooking to avoid lumps and achieve silky texture.
- Use room temperature eggs and butter for better incorporation and smoother custard.
- Handle assembled cake gently to preserve the texture contrast of crispy pastry and creamy filling.
