Step-by-Step Recipe: How to Make Vanilla Custard Cream Squares
1: Preparing the Pastry Base
- Preheat your oven to 400°F (200°C).
- Roll out the puff pastry on a baking sheet and prick the surface with a fork to prevent excessive puffing.
- Bake the pastry until it turns golden and crispy. Then, let it cool on a wire rack.
2: Making the Vanilla Custard Cream
- In a saucepan, combine eggs, sugar, cornstarch, and milk.
- Cook the mixture over medium heat, stirring continuously until it thickens to a creamy consistency.
- Remove the pan from heat and stir in the vanilla extract. For a smoother texture, strain the custard through a fine mesh sieve.
- Allow the custard to cool to room temperature, stirring occasionally to prevent a skin from forming.
3: Assembling the Squares
- Spread the cooled custard evenly over the baked pastry base.
- Place another layer of baked pastry on top of the custard.
- Then, chill the assembled dessert in the refrigerator for at least 2 hours to set.
4: Serving and Finishing Touches

- Use a sharp knife to cut the dessert into squares. Additionally, clean the knife between cuts to keep the edges neat.
Tips for Perfect Vanilla Custard Cream Squares
- Custard consistency: Stir the custard constantly while cooking to avoid lumps and ensure a smooth, creamy texture.

- Infused custard: Add flavors like chocolate, coffee, or citrus zest to the custard for a different flavor profile.
