Ingredients

For the Cream Filling

  • 1 liter milk (whole milk recommended)
  • 200 g sugar (about 1 cup)
  • 3 large eggs
  • 80 g cornstarch (⅔ cup)
  • 50 g unsalted butter (3–4 tablespoons)
  • 1 teaspoon vanilla extract

For Assembling

  • 400–500 g plain biscuits or graham crackers
    (Tea biscuits like Maria, Petit Beurre, or Digestive work beautifully.)
  • 80 g crushed biscuits for topping (optional)
  • Optional flavor additions:
    • 2 tablespoons powdered sugar for dusting
    • Grated chocolate or caramel drizzle
    • Crushed nuts (hazelnut, almond, or walnut)

Step-by-Step Instructions

1. Make the Custard Cream

The cream is the heart of this dessert, so make sure you give it the time it deserves.

  1. Pour 3/4 of the milk (about 750 ml) into a medium saucepan and place over medium heat.
  2. Add sugar and stir until dissolved. Let the mixture heat until steaming, but not boiling.
  3. In a separate bowl, whisk the remaining 250 ml milk with the cornstarch and eggs until completely smooth.
    The cornstarch is what makes the cream thick; ensure no lumps remain.
  4. Slowly pour the egg mixture into the hot milk, whisking constantly.
    Whisking prevents scrambling and ensures a silky texture.
  5. Continue cooking over medium heat, stirring constantly, until the cream thickens.
    When it reaches a pudding-like consistency, remove from heat.
  6. Add vanilla extract and butter. Stir until the butter melts completely.
  7. Cover the cream with plastic wrap touching the surface so a skin does not form. Let it cool to warm.

Your custard should now be luscious, smooth, and spoonable — not too thin, not too stiff.

2. Assemble the Cake

Choose a square or rectangular baking dish. Line it with parchment for easy removal, or leave it plain if serving directly.

  1. Spread a thin layer of warm custard cream at the bottom to anchor the biscuits.
  2. Add your first layer of biscuits, arranging them tightly side by side.
    If crumbs break or spaces remain, don’t worry — they soften and blend.
  3. Spread a generous layer of custard over the biscuits using a spatula.
  4. Repeat biscuit + cream layers until you run out of cream or reach the top of your dish.
    Usually 3 to 4 layers.
  5. Finish with a thick layer of cream on top.

3. Add the Crumb Topping

Crumbs make the cake look elegant and add a light crunch.

  • Crush a handful of biscuits (use a food processor or place in a bag and roll).
  • Sprinkle evenly over the top.
  • Optional: mix crumbs with toasted nuts for extra flavor.

4. Chill and Serve

Cover your dish and refrigerate for at least 4 hours, but overnight is ideal.

During chilling, the biscuits absorb moisture from the custard, softening into a pastry-like texture. Once fully set, slice into clean squares and enjoy the layers.

Tips for Success

  • Cream too thick? Add 1–2 tablespoons warm milk and whisk.
  • Cream too thin? Cook a bit longer; it thickens more as it cools.
  • Want extra indulgence? Add whipped cream to the cooled custard for a fluffier filling.
  • Need a quick version? Use instant vanilla pudding instead of homemade custard — but homemade tastes richer.

Flavor Variations

This recipe is delightfully flexible. Try one of these twists:

  • Chocolate Napoleon: Add 2 tablespoons cocoa powder while cooking custard.
  • Caramel Delight: Drizzle caramel between layers.
  • Coffee Version: Dip biscuits lightly in coffee — tiramisu vibes without mascarpone.
  • Fruit Layer: Add bananas, strawberries, or peaches between cream layers.
  • Nut Lovers: Sprinkle crushed hazelnuts or almonds on each layer.

Imagination is welcome — the structure works with many flavors.

Serving Ideas

Serve chilled, sliced into neat rectangles. Pair with:

  • Fresh berries
  • A dusting of powdered sugar
  • A drizzle of melted chocolate
  • A scoop of vanilla ice cream

This cake keeps wonderfully in the refrigerator for up to 4 days. It also freezes well; thaw in the fridge before serving.
