Ingredients
Choux Pastry (Eclair Dough):
- 250 ml water
- 125 g unsalted butter (82% fat)
- 125 g all-purpose flour
- 5 eggs
Vanilla Custard Cream:
- 750 ml milk
- 140 g sugar
- 1 packet bourbon vanilla sugar
- ½ vanilla pod
- 40 g flour
- 40 g cornstarch
- 6 egg yolks
- 1 pinch salt
- 100 g unsalted butter (82% fat)
- 1 sheet gelatin (1.5 g)
Instructions
Prepare the Choux Pastry:
- In a saucepan, bring water and butter to a boil. Once butter melts and mixture boils, add all flour at once and stir vigorously until dough forms a ball around the wooden spoon.
- Remove from heat and add eggs one at a time, mixing thoroughly after each. The dough may separate at first but keep stirring until it regains a smooth consistency.
- Line two 28×18 cm baking trays with parchment paper and grease edges with a small butter cube.
- Divide dough evenly between trays and spread evenly using the back of a spoon. Dough is firm and elastic, so press firmly to level it out.
- Bake at 200°C (390°F) for 25-30 minutes until golden and puffed.
- Remove from oven and let cool; the bottom layer may deflate slightly for a flatter base. The top layer can be cooled in the oven with the door slightly open to keep it puffed.
Prepare the Vanilla Custard:
- Soak gelatin sheet in cold water.
- In a bowl, whisk egg yolks with flour, cornstarch, salt, and about 50 ml milk until smooth.
- Heat remaining milk with sugar, vanilla sugar, vanilla pod seeds, and pod in a saucepan until hot but not boiling. Remove pod.
- Slowly pour hot milk into the egg mixture while whisking constantly to temper the eggs.
- Return mixture to saucepan over medium heat, stirring continuously until it thickens like soft polenta. Lower heat and keep stirring for a few more minutes.
- Remove from heat, let cool slightly, then gradually add butter, stirring until melted.
- Add drained gelatin and mix until dissolved.
- Let custard cool until warm but not hot, stirring occasionally to prevent skin forming.
Assemble the Cake:
- Place one choux pastry sheet in a tray (preferably the less perfect one). Spread custard evenly on top.
- Place the second choux pastry sheet over the custard and press lightly.
- Let cool at room temperature for about 1 hour, then refrigerate overnight or for several hours to set.
- Cut into 8 pieces with a large serrated knife (wipe the knife clean between cuts) and serve chilled.
💡 Tips
- Adding eggs gradually and mixing well ensures smooth dough.
- Cooling custard gently prevents lumps and skin formation.
