250 mlwater
130 gall-purpose flour
4 pieceseggs
1 pinchsalt
300 mlwhole milk
4 piecesegg yolks
75 ggranulated sugar
20 gcornstarch
2 tspvanilla extract
150 gdark chocolate
100 mlheavy cream
Instructions
1PREPARE THE CHOUX PASTRY DOUGH: Preheat your oven to 200°C (400°F). In a medium saucepan, combine 250 ml water, 100 g butter, and a pinch of salt. Bring to a rolling boil over medium heat, ensuring the butter completely melts. Once boiling, remove from heat and stir in 130 g all-purpose flour until the mixture forms a thick paste. Return the pan to low heat and stir constantly for 1-2 minutes to cook out excess moisture—the dough should pull away from the sides cleanly. This drying step is crucial for proper rising.
2INCORPORATE THE EGGS: Transfer the warm dough to a large bowl and let it cool for 2-3 minutes. Add the 4 eggs one at a time, beating vigorously with an electric mixer or wooden spoon after each addition until fully incorporated before adding the next egg. The mixture should be smooth, shiny, and fall slowly from a spoon—this creates the light, airy texture that makes eclairs special. If the dough appears grainy, continue mixing until it becomes completely smooth.
3PIPE AND BAKE THE ECLAIRS: Transfer the choux dough into a piping bag fitted with a 1 cm round nozzle. Pipe 10-12 cm long fingers onto parchment-lined baking sheets, spacing them about 5 cm apart as they will expand significantly. Bake at 200°C for 30-35 minutes until golden brown and firm to the touch, then reduce heat to 180°C (350°F) and bake for an additional 10 minutes to ensure they're completely dry inside. Let the baked eclairs cool completely on a wire rack before filling—this prevents the filling from making them soggy.
4MAKE THE PASTRY CREAM FILLING: Heat 300 ml whole milk in a saucepan until it steams but doesn't boil. In a bowl, whisk together 4 egg yolks, 75 g granulated sugar, and 20 g cornstarch until pale and thick, about 2-3 minutes. Slowly pour the hot milk into the egg mixture while whisking constantly to temper the eggs and prevent scrambling. Pour this mixture back into the saucepan and cook over medium heat, stirring continuously with a whisk or wooden spoon for 2-3 minutes until it thickens and coats the back of a spoon.
5FINISH THE PASTRY CREAM: Remove the pastry cream from heat and stir in 2 tsp vanilla extract. Pour the cream through a fine-mesh sieve into a clean bowl to remove any lumps, then press plastic wrap directly onto the surface to prevent a skin from forming. Chill for at least 30 minutes in the refrigerator until completely cool and thick enough to hold its shape when piped. This cooling step is essential for achieving the proper consistency.
6PREPARE THE CHOCOLATE GANACHE: Chop 150 g dark chocolate into small pieces and place in a heatproof bowl. Heat 100 ml heavy cream until it just begins to steam, then pour over the chocolate and let sit for 1-2 minutes. Whisk smooth until glossy and homogeneous—do not overmix or the ganache may become grainy. Allow to cool to room temperature for 5-10 minutes until it reaches a consistency thick enough to coat the eclairs without dripping off.
7FILL AND GLAZE THE ECLAIRS: Using a small serrated knife, carefully cut each cooled eclair horizontally about one-third of the way down. Pipe the chilled pastry cream into the bottom half using a piping bag fitted with a round nozzle, filling generously but not overstuffing. Place the top back on each eclair, then dip the top half into the cooled chocolate ganache, allowing excess to drip back into the bowl. Set on a clean wire rack and allow the ganache to set for 15-20 minutes at room temperature before serving.
