Vanilla Custard Cream Squares (Print Version)

# Ingredients:

→ Custard Filling

01 - 360 ml whole milk
02 - 360 ml heavy cream
03 - 1 vanilla bean, split and seeds scraped
04 - 4 large egg yolks
05 - 100 g granulated sugar
06 - 30 g cornstarch
07 - 1 teaspoon pure vanilla extract
08 - Pinch of salt

→ Assembly and Garnish

09 - 1 package (9 sheets) graham crackers
10 - 50 g unsweetened cocoa powder
11 - Powdered sugar, for dusting
12 - Fresh berries, for garnish (optional)

# Instructions:

01 - In a medium saucepan, combine whole milk, heavy cream, and the split vanilla bean pod with seeds. Warm over medium heat until steaming, ensuring the mixture does not boil.
02 - In a mixing bowl, whisk together egg yolks, granulated sugar, cornstarch, and a pinch of salt until the mixture is smooth and pale.
03 - Gradually pour approximately 240 ml of the hot milk mixture into the egg yolk mixture, whisking constantly to prevent curdling.
04 - Return the tempered egg yolk mixture to the saucepan with the remaining milk mixture. Cook over low heat, stirring continuously until the custard thickens and coats the back of a spoon, about 5–7 minutes. Remove from heat and blend in vanilla extract.
05 - Allow the custard to cool for about 15 minutes, then place plastic wrap directly on the surface to prevent a skin from forming. Refrigerate until thoroughly chilled, about 2 hours.
06 - Line the base of a 23 x 23 cm square baking pan with graham cracker sheets, breaking them if needed to achieve full coverage.
07 - Spread half of the chilled custard evenly over the graham cracker base.
08 - Add a second layer of graham crackers, then distribute the remaining custard over them. Top with a final layer of graham crackers.
09 - Cover the pan with plastic wrap and refrigerate for at least 4 hours or overnight for best results.
10 - Before serving, dust with cocoa powder and powdered sugar. Slice into squares and optionally garnish with fresh berries.

# Notes:

01 - For clean slicing, use a sharp knife dipped in hot water and wiped dry between each cut.
02 - Resting the dessert overnight yields a firmer, more cohesive texture.
