Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the choux pastry:

1 cup water

100 g unsalted butter

1 cup all-purpose flour

4 large eggs

1 pinch salt

For the pastry cream filling:

2 cups whole milk

4 egg yolks

1/2 cup granulated sugar

1/4 cup cornstarch

2 teaspoons vanilla extract

200 g unsalted butter, softened

For finishing:

Powdered sugar for dusting

Directions

Start by preparing the choux pastry. Preheat your oven to 390°F (200°C). Line two 8-inch round baking pans with parchment paper and lightly grease them.

In a medium saucepan, combine the water, butter, and salt. Bring the mixture to a gentle boil over medium heat. Once the butter has melted completely, add the flour all at once and stir vigorously with a wooden spoon. Continue cooking for about 2 minutes until the dough forms a smooth ball and pulls away from the sides of the pan.

Remove the dough from heat and allow it to cool for about 10 minutes. Add the eggs one at a time, mixing thoroughly after each addition until the dough becomes smooth and glossy.

Divide the dough evenly between the prepared pans and spread it unevenly to create the signature mountain-like texture. Bake for 25 to 30 minutes until golden brown and puffed. Allow the pastry layers to cool completely.

To make the pastry cream, whisk together the egg yolks, sugar, and cornstarch in a bowl until smooth. In a saucepan, heat the milk until steaming but not boiling. Slowly pour the warm milk into the egg mixture while whisking continuously.

Return the mixture to the saucepan and cook over medium heat, stirring constantly until thick and creamy. Remove from heat and stir in the vanilla extract. Cover the surface with plastic wrap and let the custard cool completely.

In a mixing bowl, beat the softened butter until fluffy. Gradually add the cooled custard, mixing until smooth and silky.

To assemble the cake, place one pastry layer on a serving plate. Spread the pastry cream evenly over the top. Carefully place the second pastry layer on top.

Refrigerate the cake for at least 2 hours before serving. Dust generously with powdered sugar just before slicing.

Variations

For a chocolate version, add melted dark chocolate to the pastry cream filling.

You can also flavor the cream with almond extract, orange zest, or coffee for a unique twist.

Fresh berries such as raspberries or strawberries make an excellent addition between the cream layers.

For extra crunch, sprinkle sliced toasted almonds over the top before serving.

Storage/Reheating

Store Karpatka in the refrigerator in an airtight container for up to 3 days. The pastry softens slightly over time, making the cake even creamier.

This dessert is best served chilled straight from the fridge.

Freezing is not recommended because the pastry cream can separate once thawed.

Karpatka does not require reheating since it is traditionally served cold.
