Step-by-Step Instructions
Step 1: Preheat the Oven and Prepare the Pan
Start by preheating your oven to 400°F (200°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides so you can lift the dessert out easily later.
This makes assembly and slicing much cleaner.
Step 2: Cook the Choux Dough Base
In a medium saucepan, combine the water and butter. Bring it to a full boil, stirring until the butter is completely melted.
Once boiling, remove the pan from heat and add the flour all at once. Stir vigorously until the mixture forms a smooth ball and pulls away from the sides.
Return the pan to low heat and cook for 1–2 minutes, stirring constantly, to dry the dough slightly.
Step 3: Add the Eggs for a Glossy Pastry
Transfer the dough into a large mixing bowl and let it cool for about 5 minutes.
Add the eggs one at a time, beating well after each addition. The dough will become smooth, thick, and glossy — perfect choux pastry texture.
It should hold its shape but still be spreadable.
Step 4: Bake the Choux Layer
Spread the pastry dough evenly into your prepared pan.
Bake for 25–30 minutes, until puffed and golden brown. Avoid opening the oven door during the first 20 minutes so the pastry doesn’t collapse.
Let the baked layer cool completely on a wire rack before assembling.
Step 5: Heat the Milk for the Custard
To begin the custard, heat 2½ cups of milk in a saucepan over medium heat until it just begins to simmer.
Do not boil — you want it hot but gentle.
Step 6: Whisk the Custard Base
In a separate bowl, whisk together the eggs, sugar, cornstarch, and the remaining ½ cup milk until smooth and lump-free.
This mixture is what will thicken into that luscious custard filling.
Step 7: Temper the Eggs Carefully
Slowly pour about one-third of the hot milk into the egg mixture while whisking constantly.
This step prevents the eggs from scrambling and ensures a silky custard texture.
Step 8: Cook Until Thick and Creamy
Pour the tempered mixture back into the saucepan with the remaining hot milk.
Cook over medium-low heat, whisking constantly, until the custard thickens and begins bubbling gently.
Continue whisking for another 1–2 minutes so the cornstarch cooks fully.
Step 9: Finish with Butter and Vanilla
Remove the custard from heat and stir in the butter and vanilla extract until smooth and glossy.
Pour it into a shallow dish and press plastic wrap directly onto the surface to prevent a skin from forming.
Chill for 2–3 hours, until completely cold and firm.
Step 10: Slice the Pastry into Two Layers
Once the pastry is fully cooled, carefully slice it horizontally into two even layers using a long serrated knife.
Take your time here, this creates the perfect top and bottom layers.
Step 11: Fill and Assemble the Squares
Place the bottom pastry layer back into the pan.
Spread the chilled custard evenly over the top, smoothing it into a thick, creamy layer.
Then gently place the top pastry layer over the custard.
Step 12: Chill, Dust, and Serve
Cover the dessert and refrigerate for at least 1 hour so everything sets beautifully.
Before serving, lift it out using the parchment paper, dust generously with powdered sugar, and slice into neat squares.
Wipe your knife between cuts for the cleanest presentation.

FAQs
