Ingredients

Scale

Choux Pastry

  • 1 cup (227g) water
  • 8 tablespoons (113g) unsalted butter, cold
  • 3/8 teaspoon table salt
  • 1 1/4 cups (150g) King Arthur Unbleached All-Purpose Flour
  • 4 large eggs

Pastry Cream

  • 1/2 cup (99g) granulated sugar
  • 5 tablespoons (35g) cornstarch
  • 4 large egg yolks
  • 2 cups (454g) milk, whole preferred
  • 1/2 cup (43g) unsweetened cocoa, Dutch-process or natural
  • 1/3 cup (57g) unsweetened baking chocolate, chopped
  • 1 tablespoon (14g) unsalted butter, cold

Glaze

  • 2/3 cup (113g) semisweet chocolate, chopped
  • 1 1/2 teaspoons light corn syrup
  • 1/2 cup (113g) heavy cream

Instructions

  1. Preheat Oven and Prepare Baking Sheets: Preheat the oven to 425°F and lightly grease or line two baking sheets with parchment paper to ensure the éclairs bake evenly and do not stick.
  2. Make Choux Pastry Base: Combine water, cold butter, and salt in a saucepan. Heat until butter melts and liquid reaches a rolling boil to prepare the moisture base for the dough.
  3. Add Flour: Remove from heat and add flour all at once, stirring vigorously to combine and begin cooking the dough.
  4. Cook Dough: Return saucepan to medium heat, stirring constantly until the dough smooths out and pulls away from the pan, about one minute, which ensures proper dough consistency.
  5. Cool Dough: Remove from heat and let dough cool for 5 to 10 minutes until under 125°F but still warm to allow safe incorporation of eggs.
  6. Add Eggs: Transfer dough to mixer and beat in eggs one at a time until smooth and glossy, beating at least 2 minutes after last egg to develop the right texture.
  7. Shape Pastry: Pipe or spoon the batter into 5″ logs about 3/4″ diameter on prepared baking sheets, forming the éclairs’ shape.
  8. Bake Pastries: Bake at 425°F for 15 minutes, then reduce oven temperature to 350°F and bake for another 25 minutes until medium golden brown without opening the oven door.
  9. Vent Pastries: Remove from oven, make a slit in the top of each éclair to release steam, then return to oven for 5 minutes. Cool on rack and split in half horizontally when cool enough to handle to prevent sogginess.
  10. Prepare Pastry Cream – Mix Dry Ingredients: In a bowl, combine sugar and cornstarch, then whisk in egg yolks to create the base for the filling.
  11. Heat Milk and Cocoa: In a saucepan, bring milk and cocoa to a simmer over medium heat, infusing the milk with chocolate flavor.
  12. Temper Egg Mixture: Slowly pour a quarter of the hot milk mixture into the yolks while whisking continuously to prevent curdling.
  13. Cook Pastry Cream: Return the egg mixture to the saucepan and cook over medium heat, stirring constantly until thickened and just boiling, then remove from heat to stop cooking.
  14. Add Chocolate and Butter: Stir in chopped baking chocolate and cold butter until melted and the cream is smooth and glossy, completing the filling.
  15. Cool Pastry Cream: Transfer cream to a bowl, cover with plastic wrap touching the surface to prevent skin formation, cool to room temperature, and refrigerate for about 2 hours until set.
  16. Make Chocolate Glaze: Combine chopped semisweet chocolate and corn syrup in a medium bowl.
  17. Heat Cream and Combine: Heat heavy cream to a simmer, then pour over the chocolate mixture, stirring until smooth and melted. Allow to cool slightly if too thin.
  18. Fill Éclairs: Pipe or spoon the chilled pastry cream into the bottom halves of the éclairs, evenly distributing the luscious filling.
  19. Glaze Tops: Dip the tops of the éclairs into the chocolate glaze and place them atop the filled bottoms to complete each éclair.
  20. Serve and Store: Serve immediately for best texture, or refrigerate and consume within a few hours. Store leftovers wrapped in the refrigerator for up to a few days; note that éclair quality decreases if frozen.

Notes

  • Do not open the oven door while baking to prevent the éclairs from collapsing.
  • When mixing eggs into the dough, it may look curdled at first but will become smooth after the last egg.
  • Splitting and exposing the pastry centers to air helps prevent sogginess.
  • Use cold butter in both the choux dough and pastry cream for better texture.
  • Pastry cream must be chilled thoroughly before filling the pastries to avoid melting the dough.
  • Éclairs do not freeze well; enjoy them fresh within a few days.
