Ingredients

Scale

Base and Layers

  • 2 packs plain graham crackers or digestive biscuits (or vanilla wafers)

Custard Filling

  • 4 cups milk
  • 1/2 cup sugar
  • 1/3 cup cornstarch
  • 2 tsp vanilla extract
  • 3 egg yolks
  • 2 tbsp butter

Icing

  • 1 cup powdered sugar
  • 1-2 tbsp milk
  • 1/2 tsp vanilla extract


Instructions

  1. Prepare the Pan: Line an 8×8 or 9×9 square pan with parchment paper to ensure easy removal of the custard slice later.
  2. Layer the Biscuits: Arrange a layer of graham crackers or digestive biscuits evenly to cover the bottom of the prepared pan completely.
  3. Make the Custard Base: In a medium saucepan, whisk together the milk, sugar, and cornstarch until the mixture is smooth with no lumps.
  4. Heat and Incorporate Egg Yolks: Place the saucepan over medium heat, stirring constantly to prevent lumps. When the mixture is hot, slowly whisk in the egg yolks carefully to temper them and avoid scrambling.
  5. Thicken the Custard: Continue stirring continuously until the custard thickens significantly, about 5 to 7 minutes. It should coat the back of a spoon.
  6. Finalize Custard: Remove the saucepan from heat and stir in butter and vanilla extract until the butter is fully melted and combined, yielding a smooth custard.
  7. Assemble First Custard Layer: Pour half of the prepared custard evenly over the first biscuit layer in the pan.
  8. Add Second Biscuit Layer: Carefully place another layer of biscuits over the custard, covering it completely.
  9. Top with Remaining Custard: Pour the remaining custard over the second biscuit layer, spreading evenly.
  10. Finish with Final Biscuit Layer: Cover the top with the last layer of biscuits, pressing gently to flatten the layers.
  11. Prepare the Icing: In a small bowl, mix powdered sugar with 1 to 2 tablespoons of milk and 1/2 teaspoon vanilla extract until smooth and spreadable.
  12. Ice the Top: Spread the icing evenly over the final biscuit layer to create a sweet finishing glaze.
  13. Chill: Place the assembled custard slice in the refrigerator for at least 4 hours, preferably overnight, to set and firm up.
  14. Serve: Once chilled, remove from the pan using the parchment paper, slice into squares and serve cold.

Notes

  • Ensure the custard is thickened properly to avoid a runny dessert.
  • Use parchment paper for easy removal and cleaner slices.
  • Overnight chilling improves texture and flavor melding.
  • You may substitute vanilla wafers for a sweeter or vanilla-flavored base instead of plain biscuits.
  • Adjust icing milk quantity for desired consistency.
