Learn how to make Karpatka, a classic Polish cream puff cake with light, airy choux pastry and the silkiest custard cream.
This cake tastes just like a giant éclair — but it’s much easier to make at home!
Soft, creamy, and beautifully rustic, Karpatka gets its name from the Carpathian Mountains, thanks to its wavy, golden pastry peaks.

INGREDIENTS (22 cm / 8.5-inch cake)
For the Pastry Layers:
70 g water
70 g milk
60 g butter
¼ tsp salt
¼ tsp sugar
100 g all-purpose flour
3 eggs (room temperature)
For the Custard Cream:
500 g milk
1 tsp vanilla extract
pinch of salt
2 eggs
160 g sugar
40 g cornstarch
150 g butter (very soft,)
For Topping:
Powdered sugar (for dusting)
TIPS FOR PERFECT KARPATKA
My cake rings: amzn.to/42a86wF
Glass bowls: amzn.to/424rgE6
✔️ Butter + Custard MUST be the same temperature
This is the #1 secret to smooth cream. If one is colder, the mixture can separate.
✔️ Poke tiny holes in the bottom layer
This helps the cream settle and keeps the cake moist.
✔️ Fill the deep waves
Add a little cream into the deeper “mountain” areas so the top layer sits nicely.
🛠️ Troubleshooting: If Your Cream Separates
If your custard cream looks grainy, curdled, or split - don’t worry! It’s very common with Karpatka. Here’s how to fix it:
Warm the bowl slightly
Place the mixing bowl over a pot of warm (not hot) water for 5–10 seconds, just to soften the butter.
Then beat again - it usually comes back together smoothly.
If it still looks a little split, don’t worry — once chilled inside the cake, it will still set beautifully.
