Ingredients

Puff pastry sheets: The secret to those classic flaky layers choose ones with real butter for best flavor
Whole milk and heavy cream: Create a custard that is luxuriously smooth not thin or watery
Granulated sugar: For perfect sweetness and a golden finish in the custard
Cornstarch: Ensures the custard slices firm and creamy no runny mess
Egg yolks: Add richness and that beautiful yellow hue always try for farm fresh eggs
Pure vanilla extract: Infuses deep comforting flavor try to avoid imitation extract for best results
Unsalted butter: Finishes the custard with shine and silkiness
Powdered sugar: For dusting that bakery style finish plus a hint of sweetness on top

Instructions

Bake the Puff Pastry:: Begin by preheating your oven to a steady 400 degrees Fahrenheit and lining two baking trays with parchment paper. Cut your thawed puff pastry sheets to fit your pan if needed and place each sheet flat on a tray. Prick them all over with a fork which prevents them from puffing too much during baking. Bake for about 12 to 15 minutes. The pastry should turn golden and look crisp. Remove from the oven cool completely and trim one sheet to fit your baking dish. Leave the second pastry sheet for your top layer.
Make the Vanilla Custard:: In a medium saucepan combine the sugar cornstarch and salt. This ensures that your thickener is evenly dispersed. Whisk in the egg yolks one at a time so your custard starts off silky. Gradually whisk in the milk and cream. Pour slowly and whisk constantly to avoid any lumps. Place over medium heat and whisk nonstop. The trick to a smooth custard is never letting it sit still. As it heats you will notice it start to thicken and begin bubbling at the edges. This usually takes 7 to 10 minutes. Remove from heat and immediately add the vanilla extract and unsalted butter. This step brings gloss and extra flavor. Stir until both are fully melted. Let your custard cool slightly for five to ten minutes. Stir every few minutes so no skin forms on top.
Assemble the Squares:: Lay your first pastry sheet in the bottom of an eight by eight inch baking dish. Pour the warm custard over this layer using a spatula to spread it evenly all the way to the edges. Carefully place your second pastry sheet on top and lightly press it down to settle it into the custard. Place the whole pan in the fridge for at least four hours but overnight is best. This helps the custard set to the perfect sliceable firmness.
Serve:: Right before serving dust the top layer with powdered sugar for the classic look. Using a sharp knife cut into neat squares. Wipe the knife between cuts for cleaner edges. Serve your custard squares well chilled for ultimate refreshment.

Cornstarch is my favorite here because it thickens without adding any flavor and gives such a dreamy texture. Every time I make these I am reminded of the holiday baking marathons with my grandmother who insisted dessert must always include custard. Some traditions are truly timeless.

Storage Tips

Cover and refrigerate leftovers in the baking dish. The custard holds up for three days without going soggy. If you want to freeze wrap tightly in plastic and then foil. Individual squares can be frozen for up to one month. Thaw overnight in the fridge and dust with fresh powdered sugar before serving.

Ingredient Substitutions

If you are dairy free a good plant based milk and vegan pastry work nicely. You can swap half and half for the milk and cream if that is what you have. Almond extract gives a different but equally delicious flavor in place of vanilla. If you do not have cornstarch arrowroot works well.

Serving Suggestions

Pile the squares onto a platter and sprinkle with extra powdered sugar just before bringing to the table. Serve with fresh berries or a spoonful of fruit compote. For a more decadent twist serve with whipped cream or drizzle with a little chocolate sauce.
