Ensure the custard is cooked slowly and stirred constantly to prevent curdling or lumps. If the custard seems too thin, continue cooking for a few more minutes until it coats the back of a spoon.
For a perfectly smooth texture, strain the custard through a fine-mesh sieve before pouring it over the crust.
When pressing the crust into the pan, use the bottom of a glass or measuring cup to create an even layer.
Chilling the crust before adding the custard helps it hold together when sliced. For clean cuts, dip a sharp knife in hot water and wipe it clean between slices.
If the custard develops a skin while cooling, place a piece of plastic wrap directly on the surface to prevent it from forming.
For a quicker set, spread the custard in a thinner layer or use a wider pan. Always allow the custard to cool slightly before refrigerating to avoid condensation.
How to Store
Vanilla Custard Cream Squares should be stored in an airtight container in the refrigerator. They will keep fresh for up to 3 days, though the crust may soften slightly over time.
For longer storage, freeze the squares in a single layer on a parchment-lined tray before transferring them to a freezer-safe container.
When freezing, separate layers with parchment paper to prevent sticking. Thaw frozen squares in the refrigerator for a few hours before serving.
Note that the texture may change slightly after freezing, but the flavor will remain delicious.
For optimal freshness, avoid leaving the squares at room temperature for extended periods, especially in warm environments. If serving outdoors, keep them chilled until ready to enjoy.
Cover any leftovers promptly to maintain their creamy texture and prevent absorption of other odors from the fridge.
