Ingredients
Scale
1 sheet puff pastry, thawed
1 tablespoon powdered sugar (for sprinkling before baking)
2 cups whole milk
1/2 cup granulated sugar
3 egg yolks
1/4 cup cornstarch
1 tablespoon butter
1 teaspoon vanilla extract
8–10 chocolate sandwich cookies, crushed
1/2 cup heavy whipping cream (for folding into custard, optional)
Extra cookie crumbs for topping
Whole cookie for garnish
Instructions
Preheat oven to 400°F (200°C). Roll puff pastry into a rectangle and place on a lined baking sheet.
Sprinkle lightly with powdered sugar for caramelized crisp layers.
Place another sheet of parchment and a second baking tray on top (to keep pastry flat). Bake 15–18 minutes until golden and crisp. Cool completely.
In a saucepan, heat milk until steaming.
In a bowl, whisk sugar, egg yolks, and cornstarch until pale and smooth. Slowly pour warm milk into mixture while whisking.
Return mixture to saucepan and cook over medium heat, stirring constantly, until thick and silky.
Remove from heat. Stir in butter and vanilla. Cool completely. For lighter texture, fold in whipped heavy cream once custard is chilled.
Fold crushed cookies into custard.
Cut baked puff pastry into three equal layers. Spread generous custard between each layer.
Finish with extra cookie crumbs and top with a whole cookie. Chill at least 1 hour before slicing for clean layers.
Notes
Serve well chilled for perfect layers
Add chocolate drizzle for extra drama
Pair with espresso or cold milk
Keep pastry weighed down while baking for flat layers
Chill thoroughly before slicing
Use very cold cream when whipping for best texture
