Chocolate Eclairs with Vanilla Pastry Cream

Method

  1. Whisk the egg yolks, sugar, cornstarch, and a pinch of salt in a bowl until pale and no lumps remain.

  2. Bring the milk to a bare simmer, then pour it slowly into the yolk mixture while whisking constantly so the eggs don’t scramble.

  3. Return everything to the saucepan and cook over medium heat, whisking hard, until the cream thickens to a pudding-like consistency and holds a bubble for a few seconds — about 2 minutes past the first bubble.

  4. Off the heat, whisk in the vanilla and 2 tablespoons butter, then press plastic wrap directly onto the surface and chill at least 2 hours, until fully set.

  5. Bring the water, ½ cup butter, 1 tablespoon sugar, and ¼ teaspoon salt to a full boil in a saucepan.

  6. Dump in the flour all at once and stir hard until the dough balls up and a thin film coats the bottom of the pan, about a minute.

  7. Scrape the dough into a bowl and beat for a minute to cool it slightly, then beat in the eggs one at a time until fully absorbed — the dough should fall off the spoon in a slow, glossy ribbon.

  8. Transfer to a piping bag fitted with a large round or star tip and pipe 4-inch batons onto a lined baking sheet, spaced well apart.

  9. Bake at 425°F for 15 minutes, then lower the oven to 350°F and keep baking until the shells are deeply golden, firm, and sound hollow when tapped, 20 to 25 more minutes.

  10. Pierce each end with a paring knife and let cool completely on a rack — this lets steam escape so they stay crisp instead of going soggy.

  11. Warm the ½ cup heavy cream in a small saucepan until it just simmers, then pour over the chopped chocolate and corn syrup and let sit a minute before stirring into a smooth, glossy glaze.

  12. Split the shells lengthwise, pipe in the chilled pastry cream, dip the tops in the warm glaze, and let set a few minutes before serving.

Notes

The pastry cream needs the full two hours in the fridge — pipe it in warm and it weeps through the choux and turns the shells soggy before anyone gets a bite. Make it a day ahead if that’s easier; it holds fine under plastic.

Same choux dough as a batch of profiteroles, piped into batons instead of mounds and dipped rather than sauced. Filled shells only keep their crunch for a couple of hours, so fill close to serving and store any extra pastry cream and unfilled shells separately.
