Polish Kremówka Papieska Recipe (Papal Cream Cake)

If you walk past a small bakery in Poland and see neat golden squares in the window, they’re likely Kremówka Papieska — the beloved Polish papal cream cake. This flaky, creamy dessert became famous thanks to Pope John Paul II, who fondly remembered eating it after school in his hometown of Wadowice.

One bite and you’ll get it: buttery puff pastry, thick vanilla custard, and a snowy dusting of powdered sugar. It’s nostalgic, rich, and full of Polish warmth.

What Is Kremówka Papieska?

Kremówka Papieska (often just kremówka) is a Polish cream cake with flaky puff pastry and a thick vanilla custard. It became widely known after Pope John Paul II mentioned it during a visit to Wadowice, his hometown. Since then, many people call it papal cream cake.

It’s a cousin to mille-feuille or napoleonka. The big difference is the filling: kremówka uses a firm, egg-rich custard set with flour and potato starch, and it’s usually finished with powdered sugar, not a glaze.

Necessary Equipment

• Mixing bowls
• Saucepan
• Whisk
• Rolling pin
• Plastic wrap
• Baking sheet + parchment paper
• Knife or pastry cutter
• 9×13-inch tray or platter
• Serrated knife (for slicing)

Key Ingredients & Substitutions

• Butter – For both pastry and custard. Choose good-quality unsalted butter.
• All-purpose flour – Used in the dough and to thicken custard.
• Potato starch – Helps the custard set firm so it slices cleanly.
• Eggs + egg yolks – Add richness to both dough and custard.
• Milk – Whole milk gives the best texture.
• Vanilla sugar – Classic in Polish baking; vanilla extract works if needed.
• White sugar – Sweetens the custard.
• Vinegar – Tenderizes the dough; keep it in.
• Powdered sugar – For that soft, snowy finish.

Step-by-Step Instructions

1. Make the Butter Mixture

Mix 1 1/3 cups butter with 3/4 cup flour until smooth. Shape into a square about 2 cm thick, wrap, and chill.
(Tip: Cold butter helps build flaky layers.)

2. Make and Laminate the Dough

Combine the remaining flour (1 3/4 cups), egg, vinegar, and warm water to make a soft dough (like pierogi dough). Roll it out, place the chilled butter square in the center, and fold the dough over it like an envelope.

Roll into a rectangle, fold into thirds like a letter, then chill. Repeat this roll–fold–chill routine 3 more times, turning the dough 90° each time.
(Tip: These folds create the classic puff pastry layers.)

3. Bake the Pastry Sheets

Divide the dough in half. Roll each piece into a rectangle. Place on parchment-lined sheets, trim edges, and prick with a fork. Bake at 425°F (220°C) for about 15 minutes, until golden. Cool fully. Cut one baked sheet into squares for the top.
(Tip: Pricking keeps the pastry from puffing too high.)

4. Make the Vanilla Custard

In a large pot, bring 3 cups milk, 4 tbsp butter, 1 cup sugar, and 2 tsp vanilla sugar to a gentle boil. In a bowl, whisk the remaining 1 1/2 cups milk with 2 eggs, 4 egg yolks, 1 cup flour, and 1/2 cup potato starch. Slowly whisk this into the hot milk. Cook, stirring, until thick and glossy. Let cool slightly.
(Tip: Stir constantly so it stays smooth and doesn’t scorch.)

5. Assemble and Chill

Place one full pastry layer on a tray. Spread the warm custard evenly. Top with the pre-cut pastry squares. Chill at least 4 hours or overnight. Dust with powdered sugar before serving.
(Tip: Use a gentle sawing motion with a serrated knife for clean slices.)

Tips

Chill the Dough: When making the puff pastry, ensure the butter is well chilled before incorporating it into the flour. This helps in creating the flaky layers characteristic of puff pastry.

Avoid Overmixing: When preparing the dough and custard, mix just until combined to avoid overworking the dough and preventing lumps in the custard.

Layering the Pastry: For an even rise and flaky texture, roll out the dough evenly and follow the folding instructions carefully.

Use a Serrated Knife: When cutting the Kremówka, use a sharp serrated knife to prevent squishing the layers and to get clean slices.

Serving Suggestions

Enjoy this Polish cream cake with strong coffee or black tea. For a classic Polish dessert spread, pair it with makowiec (poppy seed roll), karpatka, or blueberry pierogi. It’s lovely for Easter, Christmas, or name-day celebrations.

Make-Ahead & Storage

• Make Ahead: Best made the day before; the custard firms up nicely.
• Storage: Cover and refrigerate up to 3 days.
• Freezer: Not ideal — the custard doesn’t freeze well.

Common Mistakes

• Skipping folds: You need them for flaky layers.
• Runny custard: Cook until very thick — it should mound on the spoon.
• Slicing too soon: Chill completely or the cake will slump.
• Using a straight knife: A serrated knife gives the cleanest cuts.
