Ingredients

Scale

Custard Layers

  • 2 packs plain graham crackers or digestive biscuits (or vanilla wafers)
  • 4 cups milk
  • 1/2 cup sugar
  • 1/3 cup cornstarch
  • 2 tsp vanilla extract
  • 3 egg yolks
  • 2 tbsp butter

Vanilla 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 prevent sticking and make removal easier.
  2. First Biscuit Layer: Arrange a layer of graham crackers or your chosen biscuits to fully cover the bottom of the lined pan.
  3. Make Custard Base: In a medium saucepan, whisk together the milk, sugar, and cornstarch until the mixture is completely smooth with no lumps.
  4. Add Egg Yolks: Heat the mixture over medium, stirring constantly. When it becomes hot, slowly whisk in the egg yolks to temper them and avoid curdling.
  5. Thicken Custard: Continue stirring the mixture consistently for about 5 to 7 minutes until the custard thickens to a creamy, pudding-like consistency.
  6. Finish Custard: Remove the saucepan from heat and stir in the butter and vanilla extract until the custard is smooth and fully combined.
  7. Assemble First Custard Layer: Pour half of the prepared custard evenly over the first layer of biscuits.
  8. Second Biscuit Layer: Place another complete biscuit layer on top of the custard layer.
  9. Assemble Second Custard Layer: Pour the remaining custard over the second biscuit layer, smoothing it out evenly.
  10. Final Biscuit Layer: Finish with a last layer of biscuits placed on top of the custard.
  11. Prepare Vanilla Icing: Mix the powdered sugar, milk (start with 1 tbsp), and vanilla extract in a bowl until you achieve a smooth, spreadable consistency. Add more milk if necessary to reach desired thickness.
  12. Spread Icing: Evenly spread the vanilla icing over the top layer of biscuits.
  13. Chill: Refrigerate the custard slice for at least 4 hours to set properly; chilling overnight provides the best texture and flavor.
  14. Serve: Slice into squares and serve chilled for a refreshing and creamy dessert experience.

Notes

  • Use parchment paper to line the pan for easy removal and clean edges.
  • Whisk constantly when cooking the custard to prevent lumps and scorching.
  • Choose your favorite plain biscuits or wafers for the layers depending on preferred flavor and texture.
  • Adjust milk in the icing to get the perfect spreadable consistency that is not too runny.
  • Chilling time is essential for the custard slice to firm up and for the biscuits to soften slightly, creating the ideal texture.
  • Keep refrigerated and consume within 3-4 days for best freshness.
