Croatian Kremšnita: Vanilla Custard and Puff Pastry Cake
Kremšnita is a beloved Croatian dessert featuring layers of flaky puff pastry and rich, creamy vanilla custard. This recipe delivers the classic taste and texture of this iconic Central European treat, perfect for any special occasion or a delightful afternoon indulgence.
HOW TO MAKE IT
Let's cook.
01
Preheat your oven to 400°F (200°C). Unroll one sheet of puff pastry onto a baking sheet lined with parchment paper. Prick it all over with a fork to prevent excessive puffing. Bake for 15-20 minutes until golden brown and crisp. Repeat with the second sheet of puff pastry. Let both sheets cool completely.
02
In a large bowl, whisk together the egg yolks, granulated sugar, all-purpose flour, and cornstarch until smooth. This forms a thick paste.
03
In a medium saucepan, heat the whole milk over medium heat until it just begins to simmer. Slowly pour about 1/2 cup of the hot milk into the egg yolk mixture, whisking constantly to temper the eggs. Then, gradually whisk the tempered egg mixture back into the remaining hot milk in the saucepan.
04
Cook the custard over medium-low heat, stirring constantly with a whisk, for 8-10 minutes, until it thickens considerably and coats the back of a spoon. Remove from heat and stir in the vanilla extract. Cover the surface of the custard directly with plastic wrap to prevent a skin from forming and let it cool to room temperature.
05
In a separate clean bowl, beat the egg whites with an electric mixer on high speed until stiff peaks form. Gently fold the beaten egg whites into the cooled vanilla custard until just combined. Do not overmix.
06
Place one cooled puff pastry sheet into a 9x13 inch (23x33 cm) baking dish or serving platter. Spread the vanilla custard evenly over the pastry. Top with the second cooled puff pastry sheet.
07
Refrigerate the Kremšnita for at least 4 hours, or preferably overnight, to allow the custard to set and the flavors to meld. This also makes it easier to cut.
08
Before serving, dust the top generously with powdered sugar. Using a sharp, serrated knife, cut the cake into squares or rectangles.

Chef's Tips
For perfectly crisp puff pastry, ensure it's pricked thoroughly before baking. Cooling the custard completely before folding in the egg whites is crucial for a smooth, stable filling. A long chilling time is essential for the cake to set properly and for clean slices.
Easy Substitutions
You can use a combination of milk and heavy cream for an even richer custard. For a gluten-free version, use gluten-free puff pastry and a gluten-free flour blend for the custard, ensuring it's suitable for thickening. Almond extract can be used in place of vanilla for a different flavor profile.
Storage & Reheating
Store Kremšnita covered in the refrigerator for up to 3-4 days. It is best enjoyed chilled. Freezing is not recommended as it can alter the texture of the custard and pastry.
Serving Suggestions
Serve individual squares of Kremšnita with a side of fresh berries like raspberries or strawberries. A light dusting of cocoa powder can add a touch of elegance. Pair it with a cup of strong coffee or a glass of sweet dessert wine for a complete experience. It's also delightful with a dollop of unsweetened whipped cream to balance the sweetness.
Common Mistakes
One common mistake is not pricking the puff pastry enough, leading to unevenly puffed layers. Another is not tempering the egg yolks properly, resulting in scrambled eggs in the custard. Overmixing the egg whites into the custard can deflate them, making the custard less airy. Finally, not chilling the cake long enough will make it difficult to cut cleanly and the custard may be too soft.
Frequently Asked Questions
Why did my custard turn out lumpy?
Lumps usually occur if the egg yolks were not tempered properly, or if the custard was not stirred constantly while cooking, allowing it to stick and burn at the bottom.
How do I get clean slices?
Ensure the cake is thoroughly chilled, ideally overnight. Use a long, sharp serrated knife and wipe it clean between each cut for the best results.
MORE TO KNOW
The key to a successful Kremšnita lies in the custard's consistency and the puff pastry's flakiness. When making the custard, tempering the egg yolks prevents them from scrambling. Gradually adding hot milk while whisking raises their temperature slowly. Once the custard is cooked, covering it directly with plastic wrap prevents a 'skin' from forming, which can lead to lumps. Gently folding in the stiffly beaten egg whites adds lightness and airiness to the custard, creating that signature fluffy texture. Ensure your puff pastry is fully thawed but still cold when working with it for the best results.
