Karpatka: The Polish Carpathian Cream Cake

Experience the delight of Karpatka, a classic Polish dessert that combines light, airy choux pastry with a lusciously creamy vanilla filling. With its signature mountain-like ridges and a dusting of powdered sugar, this cake is as visually stunning as it is delicious!

Ingredients

For the Choux Pastry

  • Water (creates steam for the pastry to puff)
  • Unsalted butter (adds richness and flavor)
  • Salt (enhances taste)
  • All-purpose flour (provides structure)
  • Eggs (essential for binding and texture)

For the Creamy Vanilla Filling (Crème Mousseline)

  • Egg yolks (thicken the custard and add richness)
  • Sugar (sweetens the filling)
  • Potato starch or cornstarch (thickens the custard)
  • Whole milk (ensures a creamy texture)
  • Salt (balances sweetness)
  • Vanilla extract & vanilla bean paste (infuses deep flavor)
  • Unsalted butter (creates a smooth, silky texture)

For Assembly

  • Powdered sugar (dusting for a snow-capped mountain effect)

Instructions

  1. Make the Cream Filling: Whisk egg yolks and sugar until pale. Heat milk, salt, and vanilla, then temper the egg mixture. Cook until thick, then cool and whip with butter.
  2. Prepare the Choux Pastry: Boil water, butter, and salt, then mix in flour. Cook until dough forms a ball, then cool. Beat in eggs one at a time until smooth.
  3. Bake the Choux Layers: Spread dough into two springform pans, creating peaks and valleys. Bake at 380°F (193°C) for 25-28 minutes until golden.
  4. Assemble the Cake: Layer one choux pastry, spread the cream filling, and top with the second pastry. Chill for at least 1 hour, then dust with powdered sugar before serving.

Notes

  • Storage: Keep refrigerated for up to 3 days in an airtight container.
  • Serving Tip: Best enjoyed chilled with a dusting of powdered sugar just before serving.
  • Variations: Add a hint of lemon zest to the filling for a citrusy twist.
