Ingredients
- 2 sheets puff pastry, thawed but kept cold
- 4 cups whole milk, divided
- 1 1/2 cups granulated sugar
- 1 1/4 cups all-purpose flour
- 8 large eggs, carefully separated
- 3 teaspoons pure vanilla extract
- 2 tablespoons premium rum (optional)
- 1/4 teaspoon salt
- 2 cups heavy whipping cream, thoroughly chilled
- 2 tablespoons powdered sugar, plus extra for dusting
Instructions
- 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.
- Pour 3 cups of milk into a heavy-bottomed saucepan and slowly bring to a boil over medium heat.
- In a large bowl, vigorously whisk the egg yolks with granulated sugar until the mixture becomes pale and fluffy.
- 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.
- 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.
- 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.
- Place one cooled puff pastry sheet at the bottom of a 9×13-inch baking dish. Spread the custard evenly over the pastry layer.
- Refrigerate until the custard becomes firm, approximately 1-2 hours.
- When the custard has set, whip the heavy cream with powdered sugar until stiff peaks form. Spread this layer evenly over the chilled custard.
- Cut the second pastry sheet into 15 equal squares and arrange them carefully over the whipped cream layer.
- Return the dish to the refrigerator for an additional 2 hours until completely set.
- Before serving, dust the top with powdered sugar if desired. Cut into 15 squares and serve chilled.
Tips & Variations
- For a chocolate version, add 1/4 cup cocoa powder to the custard mixture before cooking
- Add a layer of fresh berries between the custard and top pastry for a fruity twist
- Ensure your custard is completely cool before assembling to prevent the pastry from becoming soggy
- For a more pronounced vanilla flavor, use vanilla bean paste instead of extract
- Make mini squares by cutting the pastry before baking and assembling individual portions
- If your custard develops lumps, strain it through a fine-mesh sieve before cooling
Serving Suggestions
These vanilla custard cream squares are perfect served chilled with a dusting of powdered sugar and a side of fresh berries. For an extra special touch, add a small dollop of lightly whipped cream and a mint leaf.
They pair beautifully with hot beverages like coffee, tea, or hot chocolate. For a dessert course, consider serving with a small glass of dessert wine or a scoop of vanilla bean ice cream on the side.
Notes
- Store leftovers in an airtight container in the refrigerator for up to 3 days
- The custard is ready when it coats the back of a spoon and a finger drawn through leaves a clear path
- For cleaner cuts, chill the assembled dessert thoroughly and use a sharp knife dipped in hot water
- If using frozen puff pastry, ensure it’s completely thawed but still cold before baking
FAQs
Can I make these vanilla custard squares ahead of time?
Yes! These squares actually benefit from being made a day ahead, allowing the flavors to meld and the custard to set properly.
Why did my custard turn lumpy?
Lumps usually form when the eggs begin to cook too quickly. To fix this, strain the custard through a fine-mesh sieve and whisk vigorously.
Can I use homemade puff pastry instead of store-bought?
Absolutely! Homemade puff pastry works wonderfully and often provides even better results, though it requires more preparation time.
How do I know when my custard is thick enough?
The custard should coat the back of a wooden spoon and when you run your finger through it, the line should remain clear without the custard running back together.
