Step‑by‑Step Instructions for Polish Custard Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While it warms up, prepare two 9-inch round cake pans by lining them with parchment paper, ensuring an easy release of the pastry later. This step sets the stage for baking your delightful Polish Custard Cake to perfection.
Step 2: Make the Pastry Dough
In a medium saucepan, combine 1 cup of water, ½ cup of unsalted butter, and ¼ teaspoon of salt over medium heat. Bring the mixture to a gentle boil, then reduce the heat and swiftly add 1 cup of all-purpose flour. Stir vigorously for about 2 minutes until the dough pulls away from the sides of the pan and forms a cohesive ball.
Step 3: Incorporate Eggs
Allow the dough to cool slightly for about 5 minutes, then add 4 large eggs one at a time, mixing well after each addition until the mixture is smooth and glossy. This process introduces air into the dough, which is crucial for the airy texture of the Karpatka.
Step 4: Bake the Pastry
Divide the dough evenly between the two prepared pans, smoothing the tops with a spatula. Bake in your preheated oven for 25–30 minutes until the pastry is puffed up and golden brown. Keep an eye on them; avoid opening the oven door to ensure they don’t deflate. Once done, remove the pans and let them cool completely.
Step 5: Prepare the Custard Filling
In a small saucepan, gently heat 2 cups of whole milk over low heat. Meanwhile, in a bowl, whisk together ¾ cup of granulated sugar, ¼ cup of cornstarch, 2 tablespoons of all-purpose flour, and the yolks of 4 large eggs. Gradually add the warm milk to this mixture, then return everything to the saucepan.
Step 6: Cook the Custard
Cook the custard over medium heat, whisking continuously for about 5–7 minutes until it thickens and bubbles gently. Watch for a creamy consistency that holds its shape. Once thickened, remove it from the heat and stir in 1 teaspoon of pure vanilla extract to enhance the flavor.
Step 7: Cool the Custard
Transfer the custard to a bowl, covering the surface with plastic wrap to prevent a skin from forming. Allow it to cool at room temperature, which typically takes about 30 minutes. This step is essential for achieving the right texture in your Polish Custard Cake.
Step 8: Combine Butter and Custard
In a mixing bowl, beat ½ cup of softened unsalted butter until light and fluffy. Gradually incorporate the cooled custard into the butter using an electric mixer, blending until smooth and well-combined. This mixture will become the luxurious filling of your cake.
Step 9: Assemble the Cake
Once your pastry layers are completely cool, carefully place one layer on a serving plate. Spread the creamy custard filling evenly over this layer, ensuring it reaches the edges. Place the second pastry layer on top, creating a beautiful tiered effect that showcases the delightful Polish Custard Cake.
Step 10: Chill and Serve
Refrigerate the assembled cake for at least 2 hours to allow the filling to set properly. Just before serving, dust the top with powdered sugar for a lovely presentation. This delightful Polish Custard Cake is now ready to be enjoyed, best paired with a cup of coffee or tea!

Polish Custard Cake Recipe FAQs
What type of flour is best for Polish Custard Cake?
All-purpose flour is highly recommended for this recipe as it provides the structure needed for the choux pastry. If you’re considering gluten-free options, be aware that these substitutes may yield a different texture, potentially compromising the light and airy nature of the cake.
How should I store leftover Polish Custard Cake?
Store the assembled Polish Custard Cake in an airtight container in the refrigerator for up to 3 days. This method preserves its freshness and texture, ensuring every slice remains delicious.
