Here’s a rich and creamy recipe for Vanilla Custard Cream Squares — also known as Vanilla Slice (or Kremówka in Polish, Mille-feuille in French). It features layers of flaky puff pastry filled with silky smooth vanilla custard, then dusted with powdered sugar. It’s a bakery-style dessert you can totally make at home!


🍰 Vanilla Custard Cream Squares

📝 Ingredients:

For the Layers:

  • 1 package (about 1 lb / 450g) frozen puff pastry, thawed

  • Powdered sugar, for dusting

For the Vanilla Custard Filling:

  • 2 ½ cups (600 ml) whole milk

  • ½ cup (100g) granulated sugar

  • ¼ cup (30g) cornstarch

  • 4 large egg yolks

  • 1 tbsp unsalted butter

  • 1 tbsp vanilla extract (or seeds from 1 vanilla bean)


👨‍🍳 Instructions:

1. Bake the Puff Pastry:

  1. Preheat oven to 400°F (200°C).

  2. Roll out and cut the pastry into two equal rectangles (about 9×13 inches).

  3. Prick all over with a fork to prevent puffing too much.

  4. Place on parchment-lined baking sheets, cover with another sheet of parchment and a baking tray to weigh it down (optional, for flat layers).

  5. Bake for 15–20 minutes, or until golden brown.

  6. Let cool completely.


2. Make the Custard:

  1. In a bowl, whisk egg yolks with sugar and cornstarch until pale and smooth.

  2. In a saucepan, heat milk until just starting to steam (do not boil).

  3. Slowly pour hot milk into the egg mixture, whisking constantly to temper.

  4. Pour mixture back into the saucepan and cook over medium heat, stirring constantly, until thick and smooth (about 5–8 minutes).

  5. Remove from heat, stir in butter and vanilla.

  6. Let cool to room temperature, stirring occasionally to prevent a skin from forming (or cover with plastic wrap pressed directly onto the surface).


3. Assemble the Squares:

  1. Place one pastry sheet in a 9×13-inch dish or tray.

  2. Spread cooled custard evenly over it.

  3. Gently place the second pastry sheet on top.

  4. Chill in fridge for at least 4 hours, or until firm enough to cut.


4. Serve:

  • Dust with powdered sugar just before serving.

  • Slice carefully with a serrated knife into squares.


✅ Tips:

  • For neater slices, freeze the assembled slice for 30–60 minutes before cutting.

  • Want extra flavor? Add a touch of almond extract or a layer of jam under the custard.

  • For a shortcut, use instant vanilla pudding mixed with whipped cream — not traditional, but still tasty.
