A decadent homemade chocolate éclair cake made with layers of crisp puff pastry, silky vanilla custard, and rich chocolate ganache. Elegant yet approachable, this bakery-style dessert is perfect for making ahead.

Ingredients

1 package (490 g) or 2 sheets puff pastry, thawed

Custard Filling:

5 large egg yolks, room temperature

3/4 cup (149 g) granulated sugar

1/3 cup (37 g) cornstarch

1/4 tsp salt

1 1/2 cups (341 g) whole milk

1/2 cup (114 g) heavy cream

1 tsp vanilla extract

2 tbsp (1 oz) butter, salted or unsalted

Chocolate Ganache:

1 1/2 cups semi-sweet chocolate chips

1 cup heavy whipping cream

2 tbsp butter, softened

1 tsp vanilla extract

1/8–1/4 tsp salt

Instructions

  1. Prepare the puff pastry: Preheat oven to 400°F (205°C). Grease an 8×8-inch baking dish. Roll out one pastry sheet until slightly larger than the dish. Prick with a fork and bake 10 minutes. Remove, place another baking sheet on top to flatten, then bake another 10 minutes until golden. Repeat with second pastry sheet. Cool and trim to fit dish.
  2. Place one pastry sheet in the bottom of the dish; set the second aside.
  3. Make the custard: Whisk egg yolks, sugar, cornstarch, and salt in a bowl. Heat milk, cream, and vanilla until just simmering. Temper yolk mixture with 1/4 cup hot milk, then slowly add 3/4 cup more. Strain back into saucepan with remaining milk. Cook on low, stirring constantly 8–10 minutes until thick. Remove from heat and stir in butter. Cool 5 minutes, then press plastic wrap onto surface and chill 3–4 hours.
  4. Make the ganache: Heat chocolate chips and cream in 20–30 second intervals until smooth. Stir in butter, vanilla, and salt. Let cool slightly.
  5. Assemble: Spread chilled custard over bottom pastry sheet. Top with second pastry sheet. Pour ganache over the top and smooth evenly.
  6. Chill at least 4 hours, ideally overnight.

Notes

Use a chocolate blend (dark + milk) for deeper flavor.

Add espresso powder to enhance the chocolate ganache.

Stir almond extract into the custard for a flavor twist.

Top with fresh berries for presentation.

Bake puff pastry up to 2 days ahead and re-crisp before assembling.
