Eclairs are one of my favorite desserts, and this recipe combines between two of my spouse’s favorite flavors: coffee and pecans.
A golden puffed and crunchy eclair, filled with coffee cream and topped with coffee glaze and pecan streusel. YUM!
Coffee Eclairs with Pecan Streusel
Based on a recipe from the book Éclair de genie of Christophe Adam, with some changes and adjustments.
For the eclairs:
- 160 ml. water
- 5 grams sugar
- 70 grams butter
- 3 grams fine salt
- 15 grams cornstarch
- 90 grams all-purpose flour
- 2-3 eggs (beaten)
For the coffee cream:
- 400 ml. milk
- 9 grams of instant coffee powder
- 3 large egg yolks
- 60 grams sugar
- 30 grams cornstarch
- 120 grams soft butter
- 180 ml. heavy cream
For pecan crumble:
- 15 grams all-purpose flour
- 15 grams natural pecans
- 15 grams butter
- 15 grams light brown sugar
- Pinch of salt
For coffee glaze:
- 150 grams white chocolate
- 65 grams natural nappage
- 45 ml. heavy cream
- 1 tsp. instant coffee powder
Coffee eclairs:
- Preheat oven to 250c degrees and turn it just before baking.
- In a medium saucepan put water, salt, sugar and butter and heat to a strong boil.
- Add cornstarch and flour and stir while cooking, until it turns into a lump of dough.
- Transfer the dough to the bowl of an electric mixer with a paddle attachment and mix on medium speed for 2-3 minutes until it cools down a little.
- Add the eggs gradually while beating until dough is elastic and smooth. Check the readiness of dough by creating a “trail” with a wooden spoon in the center of the dough – if the track remains stable, add some eggs, and if it closes a bit – the dough is ready. It is important not to add too many eggs to the dough or it may become too soft and ruined.
- Transfer the dough to a pastry bag fitted with a serrated 2 cm piping tip. On a baking tray lined with baking paper pipe 8-10 cm long eclairs. It’s important to leave some space between the eclairs.
- Bake the eclairs in the shut-down oven for about 18-20 minutes. It is important not to open the oven door during this time.
- Turn the oven to 170c degrees (while eclairs are still in) and continue to bake for 10-15 minutes. In the last 5 minutes of baking, leave the oven door open slot (put a wooden spoon in oven door). Cool completely at room temperature.
- Make 2 small holes at the bottom of each eclair.
Coffee Cream:
- In a medium saucepan put milk and coffee and heat to simmering point.
- Meanwhile, in a bowl, whisk egg yolks, sugar and cornstarch until blended.
- When the milk mixture reaches simmering point, pour about 1/3 of the milk over the egg yolk mixture, while whisking until mixture is smooth.
- Transfer the mixture back into the pan with the remaining milk and whisk well.
- Return to cook over medium heat, while whisking constantly, until you get a thick cream. The cream is ready when it thickens and begins to bubble.
- Add in the butter and stir well until dissolved.
- Transfer the cream into a flat container, cover the top with plastic wrap, and refrigerate for two hours or until it is completely cold.
- Transfer the cold cream into a clean bowl and beat until it returns to its original texture.
- In a separate mixer bowl, whip cream until stiff and fold into the coffee cream until blended.
- Transfer the cream into a piping bag fitted with a 1/2 cm round piping tip and fill the eclairs. Refrigerate.
Pecan crumble:
- In a food processor with a steel blade put flour, pecans, butter, sugar and salt and process until mixture is crumbly.
- Transfer the crumbs onto a pan lined with baking paper.
- Preheat oven to 170c degrees.
- Bake the crumbs for 10-15 minutes or until golden brown.
- Cool completely before use.
Coffee glaze:
- Chop the chocolate and put in a bowl.
- Add nappage, cream and instant coffee and solvents together in the microwave or over double boiler, until everything is melted and mixture is smooth.
- Cool for about 7-10 minutes at room temperature.
- Dip the top of each éclair in the glaze and remove excess coating.
- Sprinkle pecan crumble on top and serve.
- Keep the eclairs in a closed container in the refrigerator for up to 3-4 days, but they are at their best on the day or two after preparation.
- Instead of pecan you can use any other nut you like.
- Add the crumble just before serving to keep it crunchy.
