Instructions

1. Melt chocolate

   Place chopped dark chocolate in a microwave‑safe bowl, melt in 30‑second intervals, stirring between each until smooth. Set aside to cool completely.

   Time: PT5M

2. Heat milk with vanilla

   In a saucepan, combine 500 ml milk and 1 tsp vanilla extract. Warm over medium heat until just steaming, do not boil.

   Time: PT5M

3. Whisk yolks, sugar and cornstarch

   In a large mixing bowl, whisk together 4 egg yolks and 100 g sugar until the mixture turns pale and thick. Add 30 g cornstarch and whisk until smooth.

   Time: PT5M

4. Temper the custard

   Remove the hot milk from the heat. Gradually pour about one‑third of the hot milk into the egg‑sugar mixture while whisking constantly. Then return the entire mixture to the saucepan.

   Time: PT3M

5. Cook chocolate pastry cream

   Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens and coats the back of a spoon (about 8‑10 minutes).

   Time: PT10M

6. Finish the pastry cream

   Remove from heat. Transfer the hot cream to a clean bowl, add 50 g butter and whisk until fully incorporated. Stir in the melted chocolate from step 1, then sift 2 tbsp cocoa powder over the surface and whisk until smooth. Cover with plastic wrap touching the surface and chill for at least 2 hours.

   Time: PT5M

7. Prepare choux dough

   In a clean saucepan combine 125 ml water, 125 ml milk, 100 g butter, 15 g sugar and 0.25 tsp salt. Heat over medium‑low until butter melts and the mixture reaches a gentle boil.

   Time: PT5M

8. Add flour and dry the dough

   Remove the pan from heat and add 120 g flour all at once. Stir vigorously with a spatula until a smooth ball forms and the dough pulls away from the sides of the pan. Return to low heat for 1‑2 minutes, stirring, to dry the dough (it should no longer stick to the pan).

   Time: PT3M

9. Incorporate eggs

   Transfer the dough to a mixing bowl. Add the 4 eggs one at a time, fully mixing after each addition until the batter is glossy and smooth.

   Time: PT5M

10. Pipe and shape éclairs

    Fit a piping bag with a large plain tip, fill with the choux batter. Pipe 12‑inch (30 cm) long strips onto a parchment‑lined baking sheet, spacing them 2‑3 inches apart. Lightly smooth the tip with a damp fingertip, brush the tops with beaten egg, and score each strip lightly with a fork.

    Time: PT10M

11. Bake éclairs

    Preheat the oven to 180°C (350°F). Bake the piped choux for 30‑35 minutes, or until golden and fully risen. Do not open the oven door during the first 20 minutes.

    Time: PT35M

    Temperature: 180°C

12. Cool shells

    Remove the éclairs from the oven and let them cool completely on a wire rack before filling.

    Time: PT15M

13. Create filling holes

    Using a small piping tip, make two holes at each end and one in the middle of each éclair shell.

    Time: PT5M

14. Pipe chocolate pastry cream

    Give the chilled pastry cream a quick whisk, transfer to a piping bag fitted with a plain tip, and fill each éclair through the holes until the shell is full.

    Time: PT5M

15. Prepare chocolate glaze

    In a saucepan combine 200 ml heavy cream and 50 g sugar. Bring to a boil, then remove from heat. Add half of the cream to the chopped 150 g chocolate, let sit 30 seconds, then stir to a smooth ganache. Add the remaining cream and 30 g butter, stir until glossy.

    Time: PT10M

16. Glaze éclairs

    Allow the glaze to cool to a thick but pourable consistency (about 20 minutes at room temperature). Dip the top of each filled éclair into the glaze, letting excess drip off. Use a fingertip to smooth the edges if needed.

    Time: PT10M

17. Final cooling

    Place glazed éclairs on a rack and let set for 15 minutes before serving.

    Time: PT15M
