For the Pastry

Step‑by‑Step Instructions for Traditional Karpatka: A Creamy Polish Custard Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). Prepare two 9-inch round pans by lining the bottoms with parchment paper—this will ensure your choux pastry layers release easily after baking. Set these aside while you prepare the dough to create your delicious Polish custard cake.
Step 2: Make the Pastry Dough
In a medium saucepan, combine 1 cup of water, ¾ cup of unsalted butter, and a pinch of salt. Heat over medium until the mixture comes to a boil. Once boiling, remove it from the heat and quickly stir in 1 cup of all-purpose flour until a smooth dough forms. This step is crucial for achieving the light, airy texture of the pastry.
Step 3: Incorporate the Eggs
Allow the dough to cool for about 5 minutes before adding the eggs. Incorporate four beaten eggs one at a time, mixing vigorously until fully combined and the dough appears glossy. This step will help create the structure needed for your Polish custard cake layers to rise beautifully in the oven.
Step 4: Bake the Pastry Layers
Divide the dough evenly between the two prepared pans. Spread it out evenly with a spatula for even baking. Bake in the preheated oven for 25-30 minutes, or until the pastries are puffed and golden brown. Keep the oven door closed during baking to prevent the layers from collapsing.
Step 5: Prepare the Custard Filling
While the pastry layers are cooling, prepare the custard. In a saucepan, heat 2 cups of whole milk over medium heat until warm. In a separate bowl, whisk together ¾ cup granulated sugar, 3 tablespoons of cornstarch, 3 tablespoons of all-purpose flour, and four egg yolks until smooth. Gradually whisk in the warm milk before moving the mixture back to the saucepan.
Step 6: Thicken the Custard
Cook the custard mixture over medium heat, whisking continuously, until it thickens — about 5 minutes. You’ll know it’s ready when it coats the back of a spoon. Once thickened, remove from heat and stir in 1 tablespoon of pure vanilla extract for a rich flavor. Allow it to cool completely for the best texture in your Polish custard cake.
Step 7: Beat the Butter and Combine
In a mixing bowl, beat ½ cup of softened butter until light and fluffy using an electric mixer. Gradually mix in the cooled custard until the mixture is smooth and creamy. This step is essential to achieving a luscious filling that contrasts beautifully with the flaky pastry layers of your Karpatka.
Step 8: Assemble the Cake
Once the pastry layers are completely cooled, place one layer on a serving plate. Spread the creamy custard filling evenly over the top, ensuring it reaches the edges. Carefully place the second pastry layer on top to form your traditional Polish custard cake and press down gently to secure the layers together.
Step 9: Chill Before Serving
Cover the assembled cake with plastic wrap and chill it in the refrigerator for at least 2 hours. This chilling time will allow the flavors to meld and the custard to firm up, making each slice beautifully structured and enjoyable when served.
Step 10: Finish with Powdered Sugar
Before serving your stunning Karpatka, dust the top generously with powdered sugar for a lovely presentation. This final touch enhances the visual appeal of this delightful Polish custard cake, inviting everyone to dive into its creamy goodness!

Expert Tips for Polish Custard Cake
• Use Fresh Ingredients: Always opt for fresh eggs and vanilla extract to enhance the flavors of your Polish custard cake.
• Control Dough Temperature: Allow your pastry dough to cool properly before adding eggs; this prevents scrambling and ensures better texture.
• Don’t Rush Cooling: Always let both pastry layers and custard cool completely before assembly. This step is key to securing the perfect slice.
• Avoid Overmixing: When incorporating eggs into the dough, mix until just combined to avoid tough pastry.
• Check Oven Temperature: Use an oven thermometer to ensure your oven is at the right temperature; this is crucial for achieving the desired puff in your cake layers.
How to Store and Freeze Polish Custard Cake
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days. Best enjoyed within the first two days to maintain optimal texture and flavor.
Freezer: For longer storage, slice the Polish custard cake and wrap each piece tightly in plastic wrap, followed by aluminum foil. Freeze for up to 2 months.
Reheating: Thaw individual slices overnight in the fridge before enjoying. Optionally, let it sit at room temperature for 30 minutes to enhance the texture before serving.
Make-Ahead Tips: You can prepare the pastry layers a day in advance and store them at room temperature. Make the custard filling ahead of time as well, placing plastic wrap directly on the surface to prevent a skin from forming.
