Mastering the Art of Indulgence: A Delectable Vanilla Slice Recipe

In the world of desserts, few treats can match the classic allure of a Vanilla Slice. Also known as custard slice or mille-feuille, this timeless pastry delights the senses with its flaky layers, velvety custard, and a hint of vanilla that dances on the palate. Whether you’re a seasoned baker or a novice in the kitchen, mastering the art of creating a perfect Vanilla Slice is a rewarding endeavor. In this article, we’ll explore the secrets to crafting this indulgent delight with a step-by-step vanilla slice recipe that will have you savoring every heavenly bite.


Before you embark on your Vanilla Slice journey, gather the following ingredients:

For the Pastry:

  • 2 sheets of pre-made puff pastry
  • 1 egg (for egg wash)
  • Confectioners’ sugar (for dusting)

For the Custard Filling:

  • 2 cups whole milk
  • 1 cup heavy cream
  • 1 vanilla bean or 2 teaspoons pure vanilla extract
  • 6 egg yolks
  • 1 cup granulated sugar
  • 1/2 cup cornstarch
  • A pinch of salt


  1. Prepare the Pastry: Start by preheating your oven to 400°F (200°C). Thaw the puff pastry sheets according to the package instructions. Once thawed, place the sheets on a lightly floured surface and roll them out slightly to smooth any creases.
  2. Bake the Pastry: Line a baking sheet with parchment paper and place one puff pastry sheet on it. Using a fork, poke holes all over the pastry to prevent it from puffing too much during baking. Beat the egg and brush it over the pastry for a golden finish. Bake in the preheated oven for 15-20 minutes or until the pastry is golden brown and puffed. Repeat the process for the second sheet.
  3. Prepare the Custard Filling: While the pastry is baking, let’s create the heart of the Vanilla Slice – the luscious custard filling. In a saucepan, combine the milk and cream. If using a vanilla bean, split it lengthwise and scrape the seeds into the milk mixture. Heat the mixture over medium heat until it simmers, then remove it from heat and let it steep for about 15 minutes.
  4. Whisk the Egg Yolks: In a bowl, whisk together the egg yolks, sugar, cornstarch, and a pinch of salt until well combined. This will create a thick, pale yellow mixture.
  5. Combine and Cook: Gradually pour the warm milk mixture into the egg yolk mixture, whisking continuously to avoid curdling. Once combined, return the mixture to the saucepan and cook over medium heat, stirring constantly until it thickens to a custard consistency. If using vanilla extract instead of a bean, add it at this stage.
  6. Cool the Custard: Once the custard has thickened, remove it from heat and let it cool slightly. Cover the surface with plastic wrap to prevent a skin from forming. Allow the custard to cool to room temperature.
  7. Assemble the Vanilla Slice: Lay one sheet of baked puff pastry on a serving platter. Pour the cooled custard evenly over the pastry, spreading it with a spatula to ensure an even layer. Gently place the second sheet of puff pastry on top.
  8. Chill and Set: Refrigerate the assembled Vanilla Slice for at least 4 hours or preferably overnight. This chilling period allows the custard to set and the flavors to meld, resulting in a perfect texture and taste.
  9. Serve and Enjoy: Before serving, dust the top of the Vanilla Slice with confectioners’ sugar for an elegant finish. Use a sharp knife to cut the slices, revealing the layers of flaky pastry and creamy custard. Serve chilled and savor the sublime combination of textures and flavors in each heavenly bite.


Mastering the art of creating a delectable Vanilla Slice is a journey worth taking for any dessert enthusiast. With its layers of flaky pastry and velvety custard, this classic treat is a testament to the beauty of simplicity in baking. Armed with this vanilla slice recipe, you can confidently embark on a culinary adventure that will not only delight your taste buds but also earn you the admiration of friends and family.
