  2. 1 cup heavy cream
  3. 1 vanilla bean or 1 tablespoon vanilla extract
  4. 6 large egg yolks
  5. 1 cup granulated sugar
  6. 1/2 cup cornstarch
  7. 1/4 teaspoon salt
  8. 1/4 cup unsalted butter

For the icing:

  1. 1 cup powdered sugar
  2. 2 tablespoons milk
  3. 1/2 teaspoon vanilla extract

Step-by-Step Guide:

  1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
  2. Prepare the Puff Pastry: Lay out the puff pastry sheets on the prepared baking sheet and bake according to the package instructions or until they are golden brown and puffed up. Allow them to cool completely.
  3. Make the Vanilla Custard: a. In a saucepan, heat the milk and cream over medium heat. If using a vanilla bean, split it lengthwise and scrape the seeds into the milk mixture. If using vanilla extract, add it to the mixture. b. In a separate bowl, whisk together the egg yolks, sugar, cornstarch, and salt until well combined. c. Gradually pour the heated milk mixture into the egg mixture, whisking constantly to prevent curdling. d. Return the mixture to the saucepan and cook over medium heat, stirring continuously until it thickens into a custard-like consistency. e. Remove the pan from heat, stir in the butter until melted, and let the custard cool.
  4. Assemble the Vanilla Slice: a. Place one sheet of puff pastry on a serving dish. b. Spread the cooled vanilla custard evenly over the pastry. c. Place the second sheet of puff pastry on top of the custard layer.
  5. Prepare the Icing: In a bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more powdered sugar or milk as needed.
  6. Ice the Vanilla Slice: Pour the icing over the top layer of puff pastry, spreading it evenly with a spatula. Allow the icing to set for a few minutes.
  7. Chill and Serve: Place the assembled vanilla slice in the refrigerator for at least 2 hours to allow the custard to set and the flavors to meld. Once chilled, cut the vanilla slice into squares or rectangles and serve.
