# How To Make It:
01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a saucepan, combine water, milk, butter, sugar, and salt. Bring to a boil over medium heat.
03 - Remove from heat. Add flour all at once and stir vigorously until the dough forms and pulls away from the pan sides, about 1–2 minutes.
04 - Return saucepan to medium heat, stirring constantly for 2 more minutes to slightly dry the dough.
05 - Transfer dough to a mixing bowl and cool for 5 minutes. Beat in eggs one at a time, mixing well after each until smooth and glossy.
06 - Place dough into a piping bag with a 1/2-inch round tip. Pipe 3-inch long strips onto the prepared baking sheet spacing 1 inch apart.
07 - Bake for 20–22 minutes until puffed and golden. Turn off oven, crack door, and let pastries sit for 5 minutes. Cool completely on a rack.
08 - Simmer whole milk with vanilla bean or extract until steaming. In a bowl, whisk egg yolks, sugar, and cornstarch until pale.
09 - Gradually whisk hot milk into the yolk mixture, then return all to the saucepan. Cook over medium heat, whisking constantly until thickened and bubbling, about 2–3 minutes.
10 - Remove from heat and whisk in butter. Cover surface with plastic wrap and chill until cold.
11 - Place chocolate and butter in a bowl. Heat cream until steaming, pour over chocolate mixture, let sit 2 minutes, then stir until smooth.
12 - Pierce the bottom of each éclair with a small tip and pipe chilled pastry cream inside until filled.
13 - Dip tops of filled éclairs into chocolate glaze. Arrange on serving platter and chill until glaze sets.
