🔪 Instructions
Step 1 - Bake the Puff Pastry
-
Preheat oven to 400°F (200°C).
-
Line a baking sheet with parchment paper.
-
Place puff pastry sheets on the tray and prick all over with a fork to prevent rising too much.
-
Place another piece of parchment on top and weigh it down with another baking tray.
-
Bake for 15–18 minutes, or until golden and crisp.
-
Let cool completely, then trim into two equal rectangles to fit your pan.
Step 2 - Prepare the Vanilla Custard
-
In a saucepan, whisk together egg yolks, sugar, flour, cornstarch, and salt until smooth.
-
Slowly stream in the milk, whisking continuously to avoid lumps.
-
Place over medium heat and cook, whisking constantly, until the mixture thickens and becomes creamy — about 6–8 minutes.
-
Remove from heat and stir in the butter and vanilla extract until glossy and smooth.
-
Cover with plastic wrap directly touching the surface to prevent a skin from forming.
-
Let cool to lukewarm (not fully cold).
Step 3 - Assemble the Layers
-
Line an 8×8 inch (20×20 cm) square pan with parchment paper.
-
Place one baked puff pastry sheet at the bottom.
-
Pour the vanilla custard evenly on top.
-
Gently place the second sheet of puff pastry on the custard layer.
-
Press lightly to secure, but don’t crush the custard.
Step 4 - Chill Until Set
Refrigerate for at least 4 hours, or preferably overnight for the cleanest slices.
Step 5 - Slice and Serve
-
Remove from the pan using the parchment handles.
-
Dust generously with powdered sugar.
-
Cut into squares using a sharp serrated knife.
-
Serve as-is or with:
-
Fresh berries
-
Mint
-
A light drizzle of white chocolate
-
Tips for Perfect Custard Squares
-
Whisk constantly while cooking the custard to prevent lumps.
-
Don’t skip weighing down the puff pastry — it keeps the layers flat and crisp.
-
Chill well before slicing; warm custard will collapse.
-
Store in the fridge and consume within 3 days.
