Ingredients for Puff Pastry Vanilla Custard Squares
Here’s what you’ll need to make this delicious Puff Pastry Vanilla Custard Squares:
2 (8½ oz; 490g) sheets of puff pastry – Thawed and rolled out for that perfect flaky texture. Choose high-quality puff pastry for best results.
⅔ cup (133g) granulated sugar – This sweetener provides the perfect balance to the custard’s creaminess.
½ cup (60g) cornstarch – Essential for thickening the custard, giving it that delightful, creamy consistency.
¼ tsp kosher salt – Elevates all the flavors and enhances the sweetness.
3½ cups (795g; 830ml) whole milk – Warmed milk makes for a smooth custard; use full-fat for creaminess and richness.
6 large egg yolks – These add richness and depth to the custard, creating a silky texture.
1 vanilla bean – Cuts in half and scraped for bright, aromatic flavor, but you can substitute with 2 tsp vanilla bean paste.
4 Tbsp (60g) unsalted butter – Cold and cubed, this enriches the custard and creates a velvety finish.

How to Make Puff Pastry Vanilla Custard Squares
Follow these simple steps to prepare this delicious Puff Pastry Vanilla Custard Squares:
Step 1: Preheat and Prepare the Puff Pastry
Preheat your oven to 400°F (200°C). Line two baking trays with parchment paper. Roll out the thawed puff pastry sheets to about 9×9 inches and prick them all over with a fork to prevent puffing. Place the pastry sheets on the trays and cover with another sheet of parchment. Weigh them down with another tray.
Step 2: Bake the Pastry Sheets
Bake the puff pastry for about 35-45 minutes or until they are golden brown and crisp. Once baked, remove them from the oven and set aside to cool completely.
Step 3: Trim the Pastry
Using a serrated knife, carefully trim the baked puff pastry edges to fit an 8×8-inch square pan. This will help create neat layers in your squares.
Step 4: Make the Custard
In a medium saucepan, whisk together the granulated sugar, cornstarch, and kosher salt. Add the egg yolks and whisk until everything is well combined. In a separate saucepan, warm the whole milk over medium heat until it’s steaming—just don’t let it boil!
Step 5: Combine Milk and Egg Mixture
Slowly add 1 cup of warm milk into the sugar and egg mixture while whisking constantly. Then, gradually pour this mixture back into the saucepan with the remaining warm milk, whisking until fully mixed. Cook over medium heat while whisking until the mixture thickens and bubbles, about 5-7 minutes. Remove from heat and stir in the vanilla bean seeds and cubed butter until smooth.
Step 6: Layer and Chill
Line the 8×8 pan with aluminum foil. Place one piece of the baked puff pastry at the bottom. Pour the warm custard on top and spread it out evenly. Place the second piece of puff pastry on top and gently press down. Cover tightly with plastic wrap or foil and refrigerate for at least 4 hours or overnight.
Finally, lift your Puff Pastry Vanilla Custard Squares out of the pan using the foil overhang. Transfer to a cutting board, slice into 9 larger or 16 smaller squares, dust with powdered sugar, and serve with a flourish. These delightful bites are sure to impress anyone lucky enough to snag one!
