Step‑by‑Step Instructions for Heavenly Karpatka Cake
Step 1: Prepare Choux Pastry
In a medium saucepan over medium heat, combine 1 cup of water with 1/2 cup of unsalted butter and a pinch of salt. Stir until the butter melts and the mixture boils. Gradually add 1 cup of all-purpose flour while stirring vigorously until a smooth ball of dough forms, about 2-3 minutes. Remove from heat and let cool slightly before mixing in 4 beaten eggs, one at a time, until the dough is glossy and smooth.
Step 2: Bake Pastry
Preheat your oven to 400°F (200°C) and line two baking sheets with parchment paper. Divide the choux pastry into two equal portions and spread each onto the prepared sheets in even layers, smoothing with a spatula. Bake for 25-30 minutes until they are golden brown and puffed, keeping the oven door closed during the first half to maintain steam. Remove and allow to cool completely on wire racks.
Step 3: Make Custard Filling
In a saucepan, heat 2 cups of whole milk over medium heat until it’s steaming, but not boiling. Meanwhile, whisk together 1/2 cup of sugar, 1/4 cup of cornstarch, and 4 egg yolks in a bowl until smooth. Gradually whisk in the hot milk to temper the eggs, then return the mixture to the saucepan. Cook over medium heat, stirring constantly until thickened, about 5-7 minutes, and remove from heat. Stir in 1 teaspoon of vanilla extract.
Step 4: Assemble Cake
Once completely cooled, place one choux layer on a serving platter. Spread the rich custard filling evenly on top, making sure to reach the edges. Carefully place the second choux layer over the custard, pressing gently. Chill the assembled Heavenly Karpatka Cake in the refrigerator for at least 1-2 hours to set and allow the flavors to meld.
Step 5: Finish and Serve
Before serving, dust the top of the cake with powdered sugar for a beautiful finish. Cut into squares to showcase the layers of choux pastry and custard filling. Serve chilled with coffee or tea, and enjoy a slice of this delightful Polish dessert that celebrates homemade goodness and comforting flavors.

Make Ahead Options
These Heavenly Karpatka Cake preparations are ideal for busy home cooks looking to save time! You can prepare the choux pastry up to 24 hours in advance. Simply bake it, then store it in an airtight container at room temperature to maintain its crispness. Additionally, the custard filling can be made up to 3 days ahead; store it in the refrigerator, covered with plastic wrap directly on its surface to prevent a skin from forming. When you’re ready to assemble, layer the custard between the cooled choux pastry, chilling for at least 1-2 hours before serving. This way, you’ll enjoy all the wonderful flavors and textures of the Heavenly Karpatka Cake, all while minimizing stress on the day of your gathering!
