Ingredients
Scale
Biscuits Layer
- 2 packs plain graham crackers or digestive biscuits (or vanilla wafers)
Custard
- 4 cups milk
- 1/2 cup sugar
- 1/3 cup cornstarch
- 3 egg yolks
- 2 tsp vanilla extract
- 2 tbsp butter
Icing
- 1 cup powdered sugar
- 1-2 tbsp milk
- 1/2 tsp vanilla extract
Instructions
- Prepare Pan: Line an 8×8 or 9×9 square pan with parchment paper to prevent sticking and ensure easy removal of the custard slice.
- First Biscuit Layer: Arrange a layer of plain graham crackers or your choice of biscuit evenly to cover the bottom of the prepared pan.
- Make Custard Base: In a medium saucepan, whisk together the milk, sugar, and cornstarch until the mixture is smooth and free of lumps, providing a stable base for the custard.
- Add Egg Yolks: Heat the mixture over medium heat, stirring constantly to prevent burning. Once it begins to warm up, slowly whisk in the egg yolks to incorporate them smoothly without curdling.
- Thicken Custard: Continue stirring constantly for about 5 to 7 minutes until the custard thickens to a creamy consistency similar to pudding.
- Finish Custard: Remove the saucepan from heat and stir in the butter and vanilla extract until the butter is melted and fully combined, enriching the custard.
- Layer Custard and Biscuits: Pour half of the thickened custard over the first biscuit layer, then place another biscuit layer on top. Pour the remaining custard over this second biscuit layer.
- Final Biscuit Layer: Finish with one last layer of biscuits, pressing gently to even out the layers.
- Prepare Icing: In a small bowl, mix powdered sugar, milk (start with 1 tablespoon and add more if needed), and vanilla extract until the icing is smooth and spreadable.
- Top with Icing: Spread the vanilla icing evenly over the top biscuit layer to add sweetness and a glossy finish.
- Chill: Refrigerate the custard slice for at least 4 hours, preferably overnight, to set fully and allow flavors to meld.
- Serve: Once chilled and firm, slice the custard slice into 9 squares and serve chilled for best taste and texture.
Notes
- Use parchment paper to easily lift out the slice from the pan.
- If the icing is too thick, add a little more milk to achieve a spreadable consistency.
- For best results, chill overnight to allow the custard to set thoroughly.
- You can substitute dairy milk with plant-based milk but the texture of the custard might slightly differ.
- Ensure constant stirring while making custard to prevent lumps and burning on the stove.
