This spectacular dessert looks like it walked straight out of an artisanal European bakery, but it is surprisingly simple to make at home. While your text mentions a “cream cheese cake,” the dessert pictured in image_14.png is actually a classic Polish Karpatka (Carpathian Mountain Cake)!
It gets its unique look from a light, airy choux pastry that puffs up irregularly into “mountain peaks” during baking. When sandwiched with a rich, tangy vanilla cream cheese custard and dusted with powdered sugar, it creates an elegant, cloud-like treat that pairs beautifully with afternoon tea.
Ingredients
For the Choux Pastry Crust:
1 cup water
1/2 cup (1 stick) unsalted butter
1 cup all-purpose flour
4 large eggs
1/4 teaspoon salt
For the Cream Cheese Custard Filling:
2 cups whole milk
3/4 cup granulated sugar
1/4 cup cornstarch
2 large egg yolks
1 teaspoon vanilla extract
8 oz (1 block) cream cheese, softened to room temperature
1/2 cup unsalted butter, softened
Instructions
Step 1: Make the Choux Pastry Base
Preheat your oven to 400°F (200°C). Grease a 9×13-inch baking dish or a 9-inch springform pan and line the bottom with parchment paper. In a medium saucepan, combine the water, 1/2 cup of butter, and salt. Bring to a rolling boil over medium heat.
Step 2: Form the Dough Ball
As soon as the mixture boils, dump the flour in all at once. Stir vigorously with a wooden spoon until the flour completely absorbs the liquid and a cohesive dough ball forms, pulling away from the sides of the pan. Cook, stirring constantly, for 1 to 2 minutes to cook off the raw flour taste. Remove from heat and let cool for 5 minutes.
Step 3: Beat in the Eggs
Add the eggs one at a time to the warm dough, beating vigorously after each addition with a wooden spoon or hand mixer. The dough will look separated at first but will transform into a thick, glossy, sticky paste. Spread half of this dough into your prepared pan, smoothing it out slightly but leaving ridges (these ridges create the “mountain peaks” seen in image_14.png).
Step 4: Bake the Crusts
Bake for 20 to 25 minutes until the pastry is puffed up, crisp, and a deep golden brown. Do not open the oven door while baking, or the steam will escape and cause the pastry to collapse! Remove the first crust, let it cool, and repeat the process with the remaining half of the dough to create your top crust.
Step 5: Cook the Custard Base
In a saucepan, whisk together 1/2 cup of the milk, sugar, cornstarch, and egg yolks until smooth. Pour in the remaining 1 1/2 cups of milk. Place over medium heat, whisking constantly, until the mixture thickens into a dense, bubbling pudding texture. Remove from heat, stir in the vanilla, and press plastic wrap directly onto the surface of the custard. Let it cool completely to room temperature.
Step 6: Whip the Cream Cheese Filling
In a large bowl, beat the softened cream cheese and 1/2 cup of softened butter together until pale and completely smooth. Gradually add the cooled custard base, one large spoonful at a time, beating continuously until you have a velvety, thick, and stable cream.
Step 7: Assemble and Chill
Place your bottom choux pastry crust back into the baking pan. Spread the thick cream cheese custard evenly across the entire surface. Top with the second puffed pastry sheet, pressing down very gently.
Step 8: Dust and Serve
Refrigerate the cake for at least 4 hours (ideally overnight) so the filling sets up firmly enough to slice. Just before serving, dust the wavy top layer generously with powdered sugar to resemble snow on mountain peaks, matching the gorgeous presentation in image_14.png. Slice cleanly with a sharp, serrated knife.
