Ingredients
Choux Pastry:
- 1 cup Water
- ½ cup Unsalted butter
- 1 cup All-purpose flour
- 4 large Eggs
- ¼ tsp Salt
Coffee Pastry Cream:
- 2 cups Whole milk
- ½ cup Heavy cream
- ½ cup Granulated sugar
- 4 large Egg yolks
- 2 tbsp All-purpose flour
- 2 tbsp Instant espresso powder
- 1 tsp Vanilla extract
- Pinch Salt
Mocha Glaze:
- 4 oz Dark chocolate
- ½ cup Heavy cream
- 1 tsp Instant espresso powder
- 1 tbsp Unsalted butter
- 1–2 tbsp Powdered sugar (optional)
Instructions
- Make the Choux Pastry: Preheat your oven to 400°F (200°C). In a medium saucepan over medium heat, combine water, unsalted butter, and salt. Bring the mixture to a rolling boil to melt the butter completely and heat the liquid.
- Prepare the dough: Remove the pan from heat and quickly add all the flour at once. Stir vigorously with a wooden spoon until the dough forms a smooth ball and pulls away from the sides of the pan, indicating it is well combined and cooked slightly to form the choux base.
- Incorporate eggs: Let the dough cool for about 3 minutes to prevent cooking the eggs upon addition. Beat in the eggs one at a time, mixing thoroughly after each addition until the dough becomes smooth, shiny, and slightly elastic, perfect for piping.
- Pipe the shells: Transfer the dough to a pastry bag fitted with a plain round tip. Pipe 3-inch long logs onto a baking sheet lined with parchment paper, spacing them about 2 inches apart to allow for puffing during baking.
- Bake: Bake the éclairs for 10 minutes at 400°F (200°C). Then reduce the oven temperature to 350°F (175°C) and bake for an additional 20 to 25 minutes until they are golden and puffed. Remove from oven and cool completely on a wire rack.
- Prepare Coffee Pastry Cream: In a saucepan, combine whole milk, heavy cream, and half of the granulated sugar. Heat the mixture until it just starts to simmer, stirring occasionally to prevent scorching.
- Mix egg yolks and dry ingredients: In a mixing bowl, whisk together the egg yolks, remaining sugar, flour, instant espresso powder, vanilla extract, and a pinch of salt until the mixture is smooth and homogenous.
- Temper the eggs: Slowly pour the hot milk mixture into the yolk mixture while continuously whisking to temper the eggs and prevent curdling.
- Cook the pastry cream: Pour the combined mixture back into the saucepan and cook over medium heat, whisking constantly until it thickens and begins to bubble, ensuring a smooth and thick custard.
- Strain and chill: Remove the pastry cream from heat, strain it through a fine mesh sieve into a clean bowl to eliminate lumps. Cover the surface of the cream with plastic wrap directly to prevent skin formation. Chill thoroughly until cold.
- Make the Mocha Glaze: Place dark chocolate in a heatproof bowl. In a small saucepan, heat heavy cream with instant espresso powder until steaming but not boiling.
- Combine chocolate and cream: Pour the hot cream over the chocolate and let sit for 1 minute to melt. Stir until the chocolate is completely smooth and glossy.
- Add butter and adjust consistency: Stir in unsalted butter until melted and incorporated. If the glaze is too thin, whisk in powdered sugar 1 tablespoon at a time until the desired thickness is reached.
- Assemble the éclairs: Fill a clean pastry bag fitted with a small round tip with the chilled coffee pastry cream. Poke a small hole in the bottom of each cooled choux shell and pipe the cream inside until full but not overflowing.
- Glaze the éclairs: Dip the tops of the filled éclairs into the mocha glaze, allowing excess to drip off. Place them on a rack to let the glaze set firmly.
- Serve: Arrange your mocha éclairs beautifully on a platter and serve within 2 hours to enjoy the best texture and freshness.
Notes
- Ensure the choux dough cools slightly before adding eggs to avoid scrambling.
- Tempering eggs when making pastry cream is crucial to prevent lumps and curdling.
- Use high-quality dark chocolate for the best flavor and a shiny glaze.
- The mocha glaze can be adjusted in sweetness by adding powdered sugar as needed.
- Éclairs are best served the same day for optimal taste and texture.
- Store leftover pastry cream and éclairs separately in the refrigerator and glaze just before serving.
