Vanilla Custard Cream Squares (Print Version)

# Ingredients:

→ For the Pastry

01 - 2 sheets puff pastry, thawed but kept cold

→ For the Custard

02 - 4 cups whole milk, divided
03 - 1 1/2 cups granulated sugar
04 - 1 1/4 cups all-purpose flour
05 - 8 large eggs, carefully separated
06 - 3 teaspoons pure vanilla extract
07 - 2 tablespoons premium rum (optional)
08 - 1/4 teaspoon salt

→ For the Cream Layer

09 - 2 cups heavy whipping cream, thoroughly chilled
10 - 2 tablespoons powdered sugar, plus extra for dusting

# Instructions:

01 - Preheat your oven to 350°F (175°C). Place each puff pastry sheet on separate baking sheets and bake for 10 minutes until golden brown. Allow to cool completely.
02 - Pour 3 cups of milk into a heavy-bottomed saucepan and slowly bring to a boil over medium heat.
03 - In a large bowl, vigorously whisk the egg yolks with granulated sugar until the mixture becomes pale and fluffy.
04 - Add the flour, vanilla extract, optional rum, salt, and remaining cup of milk to the egg-sugar mixture. Whisk until completely smooth and free of lumps.
05 - Once the milk reaches a boil, gradually pour the egg mixture into the hot milk, stirring constantly. Continue cooking while stirring until the custard thickens significantly and coats the back of a spoon.
06 - In a clean bowl, beat the egg whites with an electric mixer until stiff peaks form. Gently fold them into the warm custard mixture to create a light and airy texture.
07 - Place one cooled puff pastry sheet at the bottom of a 9×13-inch baking dish. Spread the custard evenly over the pastry layer.
08 - Refrigerate until the custard becomes firm, approximately 1-2 hours.
09 - When the custard has set, whip the heavy cream with powdered sugar until stiff peaks form. Spread this layer evenly over the chilled custard.
10 - Cut the second pastry sheet into 15 equal squares and arrange them carefully over the whipped cream layer.
11 - Return the dish to the refrigerator for an additional 2 hours until completely set.
12 - Before serving, dust the top with powdered sugar if desired. Cut into 15 squares and serve chilled.

# Notes:

01 - Can be prepared a day in advance and kept refrigerated
02 - Best enjoyed within 2 days for optimal texture
03 - The rum is optional but adds depth of flavor to the custard
04 - Make sure egg whites are completely free of yolk for best results when beating
