Ingredients:
- 1/2 cup Water
- 4 Tbsp Unsalted Butter
- 1/4 tsp Salt
- 1 tsp Granulated Sugar
- 1/2 cup All-Purpose Flour
- 2 large Eggs
- 1/2 cup Heavy Cream, cold
- 2 Tbsp Unsweetened Cocoa Powder
- 1 Tbsp Powdered Sugar (for filling)
- 1 tsp Vanilla Extract
- 1 tsp Powdered Sugar (for dusting)
Instructions:
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Prepare the Panade: Combine the water, butter, salt, and granulated sugar in a medium saucepan over medium-high heat. Bring the mixture to a rolling boil, ensuring all the butter is melted.
- Remove the pan from the heat and immediately add all the all-purpose flour at once. Stir vigorously with a wooden spoon until a thick, cohesive dough (the panade) forms and pulls away from the sides.
- Return the pan to medium heat and continue stirring and cooking the dough for 2–3 minutes. This critical step cooks the starches, allowing a thin film to form on the bottom of the pan.
- Transfer the panade to a large mixing bowl or stand mixer fitted with the paddle attachment. Allow the dough to cool for 5 minutes before proceeding.
- Add the eggs one at a time, mixing well after each addition. Ensure the egg is fully incorporated before adding the next. The final dough should be smooth, shiny, and thick enough to hold its shape (if a peak falls into a soft V-shape, it is ready).
- Transfer the choux dough to a piping bag fitted with a large round tip. Pipe 6 large, evenly spaced mounds onto the prepared baking sheet.
- Bake for 15 minutes at 400°F (200°C). Then, reduce the oven temperature to 350°F (175°C) without opening the door and bake for an additional 25 minutes, or until the shells are deeply golden brown and firm.
- Turn off the oven, prop the door open slightly, and allow the puffs to cool inside for 10 minutes to prevent collapse. Transfer to a wire rack to cool completely before filling.
- Prepare the Mousse Filling: In a separate bowl, whip the heavy cream, cocoa powder, 1 Tbsp powdered sugar, and vanilla extract until stiff peaks form.
- Once the shells are cool, slice them horizontally. Fill the bottom shell generously with the chocolate mousse, replace the top, and dust with powdered sugar before serving.
