Brown Butter Mille-Feuille

Instructions

1. 1

   Preheat the oven to 200°C (400°F). Line a baking sheet with parchment paper.

   Tip: Use a high-quality parchment paper to prevent pastry from sticking.

2. 2

   In a large bowl, combine flour and cold butter. Use a pastry blender or your fingertips to work the butter into the flour until it resembles coarse crumbs.

   Tip: Avoid overmixing the dough.

3. 3

   Gradually add ice-cold water, stirring with a fork until the dough comes together in a ball.

   Tip: Don't overmix the dough.

4. 4

   Divide the dough into 4 equal pieces. Roll out each piece into a thin sheet, about 3mm thick.

   Tip: Use a pasta machine or a rolling pin to achieve an even thickness.

5. 5

   In a separate bowl, whisk together sugar, brown butter, and unsalted butter until well combined.

   Tip: Make sure the butter is at room temperature for the best results.

6. 6

   In a separate saucepan, combine heavy cream, vanilla extract, and cocoa powder. Heat over medium heat, stirring constantly, until the mixture thickens.

   Tip: Be careful not to boil the cream.

7. 7

   Assemble the mille-feuille by spreading a layer of pastry cream on the bottom sheet, followed by a layer of puff pastry, and then a layer of brown butter mixture. Repeat for 2-3 layers, finishing with a layer of pastry cream on top.

   Tip: Make sure to leave a 1cm border around the edges of each layer.

8. 8

   Refrigerate the mille-feuille for at least 2 hours to allow the flavors to meld together.

   Tip: You can also freeze it for up to 2 months.

9. 9

   Cut the mille-feuille into individual servings and serve chilled.

   Tip: You can dust it with powdered sugar or sprinkle with cocoa powder for added decoration.
