Here it is — the iconic Hungarian Custard Slice, known locally as Krémes.
A light, airy, silky custard sandwiched between crisp layers of puff pastry.
This is the real café-style version: tall, jiggly, custardy, and unforgettable.
🇭🇺 Hungarian Custard Slice (Krémes)
⭐ What Makes Krémes Special?
✔ Extra-light vanilla custard strengthened with gelatin
✔ Whipped egg whites folded in for a cloud-like texture
✔ Two layers of crisp puff pastry
✔ Classic powdered sugar finish
🍰 Ingredients
For the Pastry Layers
- 2 sheets puff pastry
- Powdered sugar (for dusting)
For the Classic Hungarian Custard
- 4 cups (1 liter) whole milk
- 1 vanilla bean or 2 tsp vanilla extract
- 8 egg yolks
- 1 cup granulated sugar
- ½ cup cornstarch
- 3 tbsp unsalted butter
- 4 egg whites
- ¼ cup sugar (for whipping whites)
- 2–3 tsp gelatin (optional but traditional for stability)
- 3 tbsp cold water (to bloom gelatin)
👩🍳 Instructions
1. Prepare Puff Pastry
- Preheat oven to 400°F (200°C).
- Prick pastry sheets all over with a fork so they stay flat.
- Bake 12–15 minutes until golden and crisp.
- Cool completely.
- Trim both sheets to the size of your baking pan.
(One will be the bottom, one the top.)
2. Make the Custard Base
- Heat milk + vanilla in a pot until steaming.
- In a bowl, whisk yolks + 1 cup sugar until pale.
- Add cornstarch and whisk smooth.
- Slowly pour hot milk into the yolk mixture (tempering).
- Return everything to pot and cook on medium, whisking constantly,
until thick and glossy — like pudding.
Remove from heat, stir in butter.
3. Add Gelatin (Traditional Version)
- Bloom gelatin in cold water for 5 minutes.
- Stir into hot custard until melted.
(This helps the slice hold its tall shape.)
4. Make the Cloud Layer
- Beat egg whites until soft peaks.
- Add ¼ cup sugar and beat to stiff, glossy peaks.
- While custard is still warm, fold egg whites into it gently.
This gives Krémes its signature airy “foam custard.”
5. Assemble
- Place one puff pastry sheet in the bottom of a baking dish.
- Pour warm custard mixture over it.
- Top with the second pastry sheet.
- Press lightly so it adheres, but don’t crush the custard.
6. Chill
Refrigerate at least 4 hours, ideally overnight,
until fully set and sliceable.
7. Serve
Dust top with powdered sugar.
Cut into squares with a sharp knife, wiping between cuts.
⭐ Tips for Perfect Krémes
- Use whole milk — flavor and texture rely on it.
- Don’t let the puff pastry puff too much: prick very well.
- Fold egg whites quickly but gently — don’t deflate.
- Chill fully for clean slices.
- Add ½ tsp almond extract for a bakery-style twist.
🍫 Variations
- Chocolate Krémes: Add melted white or milk chocolate to custard.
- French Krémes (Francia Krémes): Add a layer of whipped cream on top of custard.
