- 1 vanilla bean
- 5 egg yolks
- 1/3 cup sugar
- 3 1/2 Tbsp corn starch
- 1 Tbsp butter
- 1/2 cup heavy whipping cream
For the icing

Instructions
Make the crème pâtissière
- Slice the vanilla bean down the middle and collect seeds.
- Pour milk in a saucepan, add vanilla bean and seeds. Boil over medium heat.
- Once boiling, remove from heat and set aside. Discard vanilla bean.
- In a bowl, whisk the sugar and corn starch together then add the egg yolks and whisk until smooth.
- Whisk in half of the hot milk until incorporated and transfer back to the saucepan and remaining milk.
- Cook over medium-high heat, whisking constantly until thickened.
- Remove from heat and stir in the butter. Whisk until smooth and silky.
- Transfer into a bowl right away. Allow to cool slightly then cover with plastic wrap directly on the cream.
- Allow to cool completely at room temperature then reserve in the fridge.
To bake the puff pastry
- Preheat oven to 425°F.
- Remove dough from package and roll out onto a baking tray (lined with parchment paper if not included in the package).
- Prick holes with a fork and bake for about 30 minutes or until golden brown.
If the pastry gets too puffy or looks uneven after 5 minutes, cover with parchment paper and place a baking sheet on top pressing down. Bake this way for about 10 minutes then remove tray and parchment paper. Continue baking pastry until golden brown.
- Allow to cool completely before slicing into 3 equal rectangles.
- Remove the crème pâtissière from the fridge, whip until smooth again.
- Whip the cream to peaks and fold in the crème pâtissière.
- Place one rectangle of puff pastry on a serving plater. Evenly spread half of the crème pâtissière on it.
- Place another rectangle of puff pastry on top gently pressing down and spread remaining crème pâtissière.
- Place the last rectangle of puff pastry, clean up sides and reserve in the fridge.
Make the icing
- In a small bowl, mix together the powdered sugar, cream and melted butter. Whisk until thick and smooth.
- Melt chocolate over a hot water bath and pour into a tip-less piping bag.
- Remove the mille-feuille from fridge and evenly spread the icing on top with a spatula.
- Make a small cut at the tip of the piping bag and pipe chocolate strips in the length of the cake.
- With a tooth-pick or a skewer, make 4 vertical lines starting from top to bottom each time to create 5 equal rectangles. Then make 5 vertical lines starting from bottom to top to make the pattern.
- Place cake in the freezer for 2 hours.
- After 2 hours, slice the cake into 5 equal rectangles following the pattern and eat right away.
Skip the icing and simply dust with powdered sugar for a simpler look.
