Polish Carpathian Cream Cake (Karpatka)
Karpatka Say it: kar-PAHT-kah
Karpatka is a beloved Polish cream cake made from two layers of choux pastry filled with a thick vanilla custard cream. The top layer is baked with deep ridges that resemble the Carpathian Mountains, which gives the cake its name. It is a fixture at family celebrations, name days, and weekend gatherings across Poland. The pastry is light and slightly crisp, while the filling is silky, buttery, and generously sweet. A dusting of powdered sugar finishes it, making karpatka both homey and impressive.

Method
In a medium saucepan, combine the water, 7 tablespoons (100 g) butter, and salt and heat until the butter melts and the mixture boils. Remove from the heat, add the flour all at once, and stir vigorously until a smooth ball forms. Return to low heat and cook for 1–2 minutes, stirring, until a thin film coats the bottom of the pan.
Transfer the dough to a bowl and cool for 5 minutes. Beat in the eggs one at a time until the dough is smooth, glossy, and thick but spreadable; it should fall from the spoon in a thick ribbon.
Preheat the oven to 375°F (190°C). Grease and line two 9x13-inch (23x33 cm) pans. Divide the dough in half, spread one half evenly in the first pan, and spread the second half in the second pan, dragging a fork across it in parallel lines to create ridges.
Bake for 25–30 minutes, until puffed, golden brown, and dry to the touch. Cool completely in the pans.
In a bowl, whisk the egg yolks, potato starch, and 1/2 cup (120 ml) of the milk until smooth. In a saucepan, heat the remaining milk with the sugar and vanilla until steaming. Slowly whisk the hot milk into the yolk mixture, then return everything to the saucepan.
Cook over medium-low heat, whisking constantly, until very thick and large bubbles pop on the surface, 3–5 minutes. Remove from the heat, cover the surface with plastic wrap, and cool completely.
Beat the 1 cup (225 g) softened butter until fluffy. Add the cooled custard a spoonful at a time, beating until smooth and creamy.
Place the smooth choux layer on a serving platter and spread the cream evenly over it. Top with the ridged layer, ridges up, and press gently. Chill for at least 4 hours or overnight.
Dust with powdered sugar just before serving and cut into squares.
Regional variants
Some Polish cooks flavor the custard with lemon zest or a splash of rum, and a few add a thin layer of fruit preserves under the cream.
Cook's notes
- Let the custard cool completely before beating it into the butter; warm custard can make the cream separate.
- For the most defined ridges, pipe the top layer in rows with a piping bag instead of dragging a fork.
- Chill the cake thoroughly before slicing so the layers stay neat and the cream holds its shape.
Serve with
Serve chilled with coffee or tea.
Make ahead and storage
Karpatka is best made a day ahead; keep it covered in the refrigerator for up to 3 days.
