Description

This No-Bake Custard Slice is a delicious, creamy dessert featuring layers of crisp biscuits and smooth homemade custard, topped with a sweet vanilla icing. Perfect for a make-ahead treat that sets in the refrigerator, it requires minimal effort and no baking, making it an ideal dessert for warm days or when you want a fuss-free finish to your meal.

Ingredients

Custard and 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

Icing

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

Instructions

  1. Prepare the Pan: Line an 8×8 or 9×9 square pan with parchment paper to prevent sticking and make it easier to remove the custard slice once chilled.
  2. First Biscuit Layer: Arrange a layer of biscuits evenly to cover the bottom of the lined pan.
  3. Make Custard Base: In a saucepan, whisk together the milk, sugar, and cornstarch until fully smooth with no lumps.
  4. Cook Custard: Heat the mixture over medium heat while stirring constantly to prevent burning. When the mixture becomes hot, slowly whisk in the egg yolks to temper them and avoid scrambling.
  5. Thicken Custard: Continue stirring the mixture for 5 to 7 minutes until it thickens to a creamy custard consistency.
  6. Add Flavor and Fat: Remove the saucepan from heat and stir in the butter and vanilla extract until the custard is smooth and fully blended.
  7. Layer Custard and Biscuits: Pour half of the custard over the first biscuit layer, spreading evenly, then add another layer of biscuits on top.
  8. Repeat Layers: Pour the remaining custard over the second biscuit layer, then finish with a final layer of biscuits.
  9. Prepare Icing: Mix powdered sugar, milk, and vanilla together until you get a smooth icing consistency.
  10. Ice the Top: Spread the icing evenly over the final biscuit layer to seal and sweeten the top.
  11. Chill to Set: Refrigerate the assembled custard slice for at least 4 hours, though overnight chilling yields the best texture and flavor fusion.
  12. Serve: Once set, slice into squares and serve chilled for a refreshing dessert.

Notes

  • For a gluten-free option, use gluten-free biscuits.
  • The custard needs constant stirring to prevent lumps and burning.
  • Use fresh egg yolks and ensure proper whisking to avoid scrambled eggs in custard.
  • Overnight chilling enhances texture and flavor melding.
  • You can substitute vanilla wafers for digestive biscuits for a sweeter flavor.
