Ingredients You’ll Need
The beauty of this Karpatka Cake (Polish Carpathian Cream Cake) Recipe lies in its use of simple, high-quality ingredients that come together to create something extraordinary. Every item serves a purpose—whether it’s the butter lending richness to the dough and creamy filling or the eggs adding structure and lightness. Let’s dive into the essentials you’ll want to gather.
- 1 cup water: Provides moisture and steam for the choux pastry to puff up beautifully in the oven.
- 1/2 cup unsalted butter: Adds richness and flavor, essential for both the dough and the cream.
- 1 cup all-purpose flour: The backbone of the choux pastry, giving it structure and elasticity.
- 1/4 tsp salt: Balances the sweetness and enhances the overall flavors.
- 4 large eggs: Key to creating that glossy, airy texture in the pastry layers.
- 2 cups whole milk: Gives the custard filling its creamy body and velvety mouthfeel.
- 1/2 cup granulated sugar: Sweetens the custard perfectly without overpowering it.
- 1/4 cup cornstarch: Thickens the custard to hold its shape between the pastry layers.
- 4 large egg yolks: Enrich the custard, making it smooth and decadent.
- 2 tsp vanilla extract: Infuses the cream with warm, aromatic notes for that classic flavor.
- 1/2 cup unsalted butter (softened): Whipped into the custard to create a luscious, buttery finish.
- Powdered sugar (for dusting): Adds a pretty, snowy topping that invites every bite.
How to Make Karpatka Cake (Polish Carpathian Cream Cake) Recipe
Step 1: Prepare the Choux Pastry
Start by preheating your oven to 375°F (190°C) and greasing two 9-inch round cake pans. This sets the stage for the airy pastry layers that give the Karpatka its signature texture. Greasing the pans well ensures the delicate dough won’t stick, so you get that perfect rise and easy removal after baking.
Step 2: Cook the Dough Base
In a saucepan, combine the water and butter and bring to a boil. This hot mixture is essential for creating the ideal environment for the flour to absorb moisture evenly. Once boiling, remove from heat and stir in the flour and salt quickly, working the mixture until it forms a smooth dough. This step is crucial for developing the pastry’s structure.
Step 3: Dry the Dough Slightly
Return the pan to low heat and stir constantly for about 1 to 2 minutes. This process helps to dry out the dough just enough to give it the right texture when baked—too much moisture, and the pastry won’t puff up properly. Once done, remove from heat and let it cool slightly before moving on.
Step 4: Incorporate the Eggs
Beat the eggs in one at a time into the cooled dough, mixing thoroughly after each addition. This step transforms the dense dough into a glossy, smooth batter ready to rise beautifully in the oven. The eggs are the magic that creates those delightful pockets of air inside the layers.
Step 5: Bake the Pastry Layers
Divide the dough evenly between your prepared cake pans, spreading it thinly right up to the edges. Bake for 25 to 30 minutes until golden and puffed. Resist the temptation to open the oven door early, as this could cause the delicate layers to collapse. Once baked, allow the layers to cool completely before moving on to the custard filling.
Step 6: Prepare the Cream Filling
Heat 1 1/2 cups of whole milk over medium heat until warm but not boiling. In a separate bowl, whisk together the sugar, cornstarch, egg yolks, and the remaining 1/2 cup milk until smooth with no lumps. Slowly pour the warm milk into the egg mixture, whisking continuously to temper the eggs gently and prevent curdling. Return this mixture to the saucepan and cook on medium heat until it thickens to a custard-like consistency, stirring constantly.
Step 7: Finish the Cream
Remove the custard from the heat and stir in the vanilla extract. Let it cool until just warm, then beat in the softened butter until everything is perfectly smooth and creamy. This butter infusion makes the filling incredibly rich and smooth, raising the whole dessert to the next level.
Step 8: Assemble the Karpatka Cake (Polish Carpathian Cream Cake) Recipe
Place one of the choux pastry layers on your serving plate. Spread the luscious vanilla custard evenly over it. Top with the second pastry layer and finish by dusting generously with powdered sugar. The final effect is a mountain-like cake resembling the peaks of the Carpathian Mountains, which is how it got its charming name.
How to Serve Karpatka Cake (Polish Carpathian Cream Cake) Recipe

Garnishes
While the powdered sugar dusting is traditional and beautiful, you can take the presentation up a notch by adding fresh berries like raspberries or blueberries on top. A light sprinkle of cinnamon or cocoa powder can introduce warm depth, complementing the vanilla cream perfectly.
Side Dishes
This cake is a star all on its own, but pairing it with a simple cup of strong coffee or a delicate herbal tea brings out its best qualities. A dollop of lightly whipped cream or a small scoop of vanilla ice cream beside the slice can also add a luxurious touch that guests will love.
Creative Ways to Present
Try slicing the Karpatka Cake (Polish Carpathian Cream Cake) Recipe into smaller, individual rectangles and serving them on delicate dessert plates with a drizzle of chocolate or caramel sauce. You can also layer it with fresh fruit between the pastry layers for a colorful surprise that adds fresh flavor and beautiful contrast.
Make Ahead and Storage
Storing Leftovers
This cake can be refrigerated in an airtight container for up to three days. The pastry layers might soften slightly, but the flavors meld beautifully over time, making each bite just as comforting. Be sure to let it come to room temperature before serving for the best experience.
Freezing
If you want to save the Karpatka Cake (Polish Carpathian Cream Cake) Recipe for later, freeze it uncovered for an hour to harden the cream, then wrap tightly in plastic wrap and aluminum foil. It freezes well for up to a month. Thaw it overnight in the refrigerator before enjoying.
Reheating
Since this is a cream-filled cake, reheating isn’t recommended as it can alter the texture of the custard. Instead, serve chilled or at room temperature to preserve the luscious cream filling and delicate pastry layers.
