Here’s a classic Polish Karpatka recipe — a soft choux pastry cake filled with creamy custard, named after the Carpathian Mountains because of its “mountainous” top:
🏔️ Karpatka (Polish Cream-Filled Cake)
Ingredients
For the Choux Pastry (Cake Layers):
- 1 cup (240 ml) water
- 1/2 cup (115 g) unsalted butter
- 1 cup (125 g) all-purpose flour
- 4 large eggs
- Pinch of salt
For the Cream Filling (Custard Cream):
- 2 cups (480 ml) milk
- 1/2 cup (100 g) sugar
- 1/4 cup (30 g) all-purpose flour
- 2 tbsp cornstarch
- 4 large egg yolks
- 1 tsp vanilla extract
- 1/2 cup (115 g) unsalted butter, softened
Optional: Powdered sugar for dusting
Instructions
1️⃣ Prepare the Choux Pastry
- Preheat oven to 400°F (200°C).
- In a saucepan, bring water, butter, and a pinch of salt to a boil.
- Remove from heat, add flour all at once, and stir vigorously until a smooth dough forms.
- Return to low heat and cook 1–2 minutes, stirring constantly, to dry slightly.
- Transfer dough to a bowl and let cool slightly.
- Beat in eggs one at a time until fully incorporated and smooth.
2️⃣ Bake Cake Layers
- Line two baking sheets (or one large sheet, halved later) with parchment paper.
- Spread half of the dough on one sheet and the other half on the second sheet (or in separate pans).
- Bake 25–30 minutes until golden and puffed. Do not open oven early.
- Remove and let cool completely.
3️⃣ Make the Cream Filling
- In a saucepan, heat milk until almost boiling.
- In a bowl, whisk sugar, flour, cornstarch, and egg yolks until smooth.
- Slowly pour hot milk into egg mixture, whisking constantly to temper eggs.
- Return mixture to saucepan and cook over medium heat, stirring, until thickened.
- Remove from heat, stir in vanilla, and let cool slightly.
- Beat in softened butter until smooth and creamy.
4️⃣ Assemble Karpatka
- Place one choux pastry layer on a serving plate.
- Spread the custard cream evenly on top.
- Place the second pastry layer over the cream.
- Dust with powdered sugar before serving.
Tips for Perfect Karpatka
- Chill the cream slightly before spreading for easier assembly.
- Cut with a serrated knife to avoid squishing the layers.
- Optional flavor twists: Add a teaspoon of rum or almond extract to the cream.
- Make-ahead: Karpatka tastes even better after a few hours in the fridge.
If you want, I can also give a “simpler, single-pan Karpatka version” that’s quicker but still creamy and fluffy.
Do you want me to do that?
