Description
Karpatka is a classic Polish dessert known as Carpathian Cream Cake, featuring layers of light, fluffy choux pastry filled with a rich and creamy vanilla-flavored crème mousseline. This luscious cake is inspired by the rugged peaks of the Carpathian Mountains, reflected in the uneven, mountain-like texture of the baked choux. Perfect for special occasions or a decadent treat, Karpatka combines the delicate crumb of choux dough with a smooth, buttery pastry cream for an unforgettable dessert experience.
Ingredients
Scale
Crème Mousseline
- 5 large egg yolks
- 2/3 cup granulated white sugar (divided into 1/3 cup + 1/3 cup)
- 7 tablespoons potato starch
- 2 1/2 cups whole milk
- 1/4 teaspoon salt
- 2 teaspoons pure vanilla extract
- 2 teaspoons vanilla bean paste or additional vanilla extract
- 200 grams unsalted butter at room temperature (about 14 tablespoons + 1 teaspoon)
- 2 tablespoons granulated white sugar
Choux Pastry
- 3/4 cup water
- 6 tablespoons unsalted butter
- 1/8 teaspoon salt
- 3/4 cup all-purpose flour
- 3 large eggs
- 1 large egg yolk
Other
- Butter to grease the pans
- Powdered sugar for dusting on top
Instructions
- Make the Crème Pâtissière: In a medium bowl, beat together the egg yolks and 1/3 cup sugar with an electric mixer until thick and pale yellow. Incorporate the potato starch until smooth.
- Heat the milk mixture: Combine the remaining 1/3 cup sugar, whole milk, and salt in a medium saucepan over medium heat and bring to a gentle simmer.
- Temper the eggs: Remove milk from heat. Gradually whisk about 1 cup of hot milk into the egg yolk mixture a few drops at a time to prevent curdling. Then pour this mixture back into the pot; add vanilla extract and vanilla bean paste.
- Thicken the custard: Return the pan to low heat and whisk constantly until custard thickens, about less than a minute.
- Cool the custard: Transfer custard to a bowl, cover with plastic wrap directly on the surface to prevent skin formation, and cool to room temperature.
- Prepare the choux pastry pans: Preheat oven to 380°F. Line bottoms of two 8 or 9-inch springform pans with parchment; grease sides with butter.
- Make the choux dough: In a saucepan over medium heat, melt butter with water and salt. When melted, remove from heat and stir in flour all at once. Return to low heat and cook, stirring constantly, until dough forms a ball and leaves residue on bottom, about 2 minutes.
- Incorporate the eggs: Transfer dough to a bowl and let cool 5-10 minutes until warm but not hot. Using a mixer, beat in eggs and egg yolk one at a time until smooth and glossy.
- Shape the dough: Divide dough between pans, spreading to cover bottoms. Use back of spoon to create uneven peaks and divots resembling mountain ridges.
- Bake the choux cakes: Bake 25-28 minutes until puffed and golden brown.
- Cool the cakes: Let cool 10 minutes in pans, then remove and cool completely on wire racks.
- Finish the crème mousseline: Beat butter and 2 tablespoons sugar with a mixer in a large bowl until pale and fluffy. Gradually add custard a spoonful at a time, mixing well after each addition until all incorporated. Continue beating until light and fluffy, about 5 minutes.
- Cover the crème mousseline: If cakes aren’t completely cool, cover the cream with plastic wrap directly on the surface to prevent skin.
- Assemble the cake: Place one choux cake in a springform pan and spread the crème mousseline evenly on top. Place the second cake on top.
- Chill and serve: Refrigerate the assembled cake for at least 1 hour before removing the springform pan. Just before serving, dust the top with powdered sugar.
Notes
- Ensure the custard is properly tempered when combining hot milk with egg yolks to prevent scrambling.
- The uneven spreading of the choux dough mimics the appearance of the Carpathian Mountains.
- Greasing the springform pan sides and lining with parchment ensures easy removal without damage.
- Room temperature butter is key for smooth incorporation into the custard to make crème mousseline.
- Chilling the cake helps the flavors meld and sets the cream for easier slicing.
- Use high-quality vanilla extract and vanilla bean paste for the richest flavor.
