Ingredients

Scale

For the Choux Pastry

  • 1 cup water
  • 100g unsalted butter
  • 1 cup all-purpose flour
  • Pinch of salt
  • 4 large eggs (room temperature)

For the Custard Filling

  • 4 large eggs
  • 1 cup sugar
  • 3 tablespoons cornstarch
  • 2 cups milk
  • 1 teaspoon vanilla extract

Optional Garnishes and Variations

  • Powdered sugar for dusting
  • Fresh berries or edible flowers
  • Cocoa powder (for chocolate infusion)
  • Chopped toasted almonds or walnuts
  • Spices such as cinnamon, cardamom, or lemon zest
  • Plant-based milk (almond or oat) and vegan butter for dairy-free version

Instructions

  1. Prepare the Choux Pastry: Start by boiling water, butter, and a pinch of salt together until the butter melts completely. Remove from heat and stir in the flour quickly until a smooth dough forms and pulls away from the pot. Allow it to cool slightly before beating in eggs one at a time until the dough is glossy and thick yet pipeable.
  2. Bake the Pastry Layers: Split the dough evenly between two baking sheets lined with parchment paper. Use a spatula to spread it into roughly rectangular shapes about half an inch thick. Bake in a preheated oven at 200°C (390°F) until the surfaces puff up and turn golden brown, approximately 25-30 minutes. Ensure you do not open the oven during baking to avoid collapsing.
  3. Make the Custard Filling: While the pastry cools, whisk together sugar, cornstarch, and eggs in a saucepan. Gradually add warm milk and vanilla extract, stirring constantly. Place the mixture over medium heat and keep stirring until it thickens to a pudding-like consistency. Once thickened, remove from heat and set aside to cool, covering with plastic wrap to prevent a skin from forming.
  4. Assemble the Cake: Place one sheet of cooled pastry on your serving plate and generously spread the chilled custard over it. Top with the second pastry sheet, gently pressing down to secure the layers. Refrigerate the cake for at least two hours before serving to allow the flavors to meld and the texture to set.

Notes

  • Use room temperature eggs to help the dough absorb them evenly for smooth consistency.
  • Do not rush pastry cooling; completely cool the choux layers before adding custard to prevent melting.
  • Beat eggs into dough slowly; adding eggs gradually ensures the right dough texture without making it too runny.
  • Keep stirring custard constantly to prevent lumps and scorching until thickened and smooth.
  • Chill the assembled cake before slicing to help cut clean slices without smudging the custard.
