Vanilla Slice (Krempita): A Taste of Eastern Europe

I remember the first time I tasted Krempita. It was at a small Serbian bakery, tucked away on a side street during a family trip to Belgrade. The unassuming exterior hid a treasure trove of pastries, but it was the Krempita that caught my eye – layers of golden puff pastry embracing a cloud of vanilla cream. The first bite was pure bliss – the delicate crunch of the pastry, the cool, velvety cream that melted on my tongue. It was a revelation, a taste of pure comfort and simple elegance that I’ve been chasing ever since. Now, I am excited to share my version of this delightful dessert.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 20-25 minutes
• Total Time: 2 hours, 30 minutes (includes chilling time)
• Servings: 12
• Yield: One 9×13 inch pan
• Dietary Type: Not suitable for dairy-free or gluten-free diets

Ingredients

• 2 sheets puff pastry
• 6 1/3 cups (1590 ml) milk
• 5 1/4 ounces (150 g) cornstarch
• 1 ounce (28 g) vanilla sugar
• 8 egg yolks
• 7 ounces (200 g) sugar
• 8 ounces (227 g) whipping cream, whipped with stabilizer

Equipment Needed

• Jelly roll pan
• 9×13 inch square pan
• Mixing bowls
• Whisk
• Electric mixer
• Saucepan

Instructions

1. Begin by thawing the puff pastry sheets according to the package directions. Once thawed, lightly flour your work surface and roll out each sheet slightly. This ensures even baking and prevents excessive puffing.
2. Preheat your oven to 400°F (200°C). Place the rolled-out puff pastry sheets on a jelly roll pan and bake according to the package directions, or until golden brown and cooked through, typically about 20-25 minutes. Watch them carefully to prevent burning.
3. Once baked, let the pastry sheets cool completely on a wire rack. This is crucial for preventing the cream from melting later.
4. While the pastry cools, prepare your 9×13 inch square pan. Trim the cooled pastry sheets to fit the pan precisely. Set one sheet aside. This will form the base of your Krempita. Cut the other sheet into 12 equal squares. These squares will be the decorative top layer.
5. Now, for the vanilla cream filling: In a large bowl, whisk together the egg yolks and sugar until the mixture is light and frothy. This incorporates air and helps create a smooth, rich custard.
6. In a separate small bowl, whisk together cornstarch and 1 cup (240 ml) of milk from the total amount. Ensure there are no lumps in the cornstarch mixture.
7. In a medium saucepan, combine the remaining 5 1/3 cups (1350 ml) of milk and vanilla sugar. Bring this mixture to a boil over medium heat, stirring occasionally to prevent scorching.
8. Once the milk mixture reaches a boil, reduce the heat to low and slowly whisk in the egg yolk mixture, followed by the cornstarch mixture. Stir constantly and vigorously to prevent lumps from forming.
9. Continue to cook, stirring constantly, for about 1 minute, or until the custard thickens significantly and coats the back of a spoon. It should be thick enough to hold its shape.
10. Transfer the thickened custard to a large mixing bowl and let it cool completely. To prevent a skin from forming on top, press a piece of plastic wrap directly onto the surface of the custard.
11. While the custard cools, whip the whipping cream with a stabilizer (such as powdered sugar or cornstarch) until stiff peaks form. This ensures the cream holds its shape and doesn’t deflate in the filling.
12. Once the custard is completely cooled, gently fold in the whipped cream until just combined. Be careful not to overmix, as this can deflate the cream.
13. Assemble the Krempita: Place the whole puff pastry sheet into the bottom of the prepared 9×13 inch pan.
14. Evenly spread the vanilla cream filling over the pastry base.
15. Arrange the cut puff pastry squares evenly over the top of the filling.
16. Refrigerate the Krempita for at least 2 hours, or preferably overnight, to allow the filling to set completely.
17. Before serving, dust generously with powdered sugar.

Expert Tips & Tricks

• Preventing a Soggy Crust: Ensure the baked puff pastry is completely cooled before adding the filling. You can also lightly brush the bottom crust with melted white chocolate to create a moisture barrier.
• Achieving a Smooth Custard: Whisk constantly while cooking the custard to prevent lumps from forming. If lumps do occur, strain the custard through a fine-mesh sieve.
• Whipped Cream Stability: Adding a stabilizer to the whipped cream, such as powdered sugar or cornstarch (about 1 tablespoon per cup of cream), helps it hold its shape longer. You can also use a commercial whipped cream stabilizer.
• Even Pastry Baking: Prick the puff pastry all over with a fork before baking to prevent it from puffing up unevenly.

Serving & Storage Suggestions

Serve the Vanilla Slice (Krempita) chilled. Dust generously with powdered sugar just before serving. For an extra touch, you can add a dollop of whipped cream or a sprinkle of cocoa powder.

Store leftover Krempita in an airtight container in the refrigerator for up to 3 days. The pastry will soften over time, but the flavor will remain delicious. Freezing is not recommended, as it can alter the texture of the cream.

• Almond Krempita: Add a teaspoon of almond extract to the custard for a nutty flavor. You can also sprinkle sliced almonds on top of the finished Krempita.
• Lower-Fat Version: Use low-fat milk and reduce the amount of sugar slightly. Be aware that this will affect the richness and texture of the filling.

FAQs (Frequently Asked Questions)

Q: Can I use store-bought custard instead of making my own?
A: While it’s possible, the flavor and texture won’t be quite the same. Homemade custard provides a superior taste and allows you to control the sweetness and vanilla intensity.

Q: My custard is too thick. What can I do?
A: Gently whisk in a tablespoon or two of milk at a time until it reaches the desired consistency.

Q: How do I prevent the puff pastry from shrinking during baking?
A: Avoid over-handling the dough and ensure your oven is properly preheated. Pricking the pastry with a fork also helps.

Q: Can I make this Krempita ahead of time?
A: Absolutely! In fact, it’s best made a day in advance to allow the flavors to meld and the filling to set properly.

Q: Why is my whipped cream separating in the filling?
A: Overmixing after adding the whipped cream can cause it to separate. Fold gently until just combined. Using a stabilizer in the whipped cream also helps.
