Ingredients
Method
- Preheat the oven to 180°C. Line a baking tray with parchment paper.
- In a saucepan, bring the water, milk, butter, salt, and sugar to a boil.
- Add the flour all at once and stir vigorously over medium heat for about 2 minutes until the dough pulls away from the sides and forms a thin film on the bottom of the pan.
- Remove from heat and add the eggs one at a time, mixing well after each addition until the dough becomes smooth and forms a ribbon.
- Transfer the dough to a piping bag and pipe 4 cm rounds onto the baking tray.
- Bake for 30 to 35 minutes without opening the oven door. Allow the choux to cool completely.
- Prepare the coffee pastry cream by heating the milk with the coffee. In a bowl, whisk the egg yolks with sugar and cornstarch.
- Pour the hot milk over the egg mixture while whisking, then return everything to the saucepan and cook until thickened.
- Cover the pastry cream with plastic wrap touching the surface and let it cool completely.
- For the ganache, pour the hot cream over the chopped white chocolate and stir until smooth.
- Add the cold cream, mix well, and refrigerate for at least 4 hours.
- Whip the chilled ganache with a mixer until it becomes light and fluffy like whipped cream.
- Cut the tops off the cooled choux. Fill the base with the coffee pastry cream.
- Pipe a generous swirl of whipped white chocolate ganache on top and place the lid back on.
- Finish with a light dusting of powdered sugar before serving.
Notes
Use high-quality white chocolate containing at least 30% cocoa butter for the best ganache texture. Make sure the ganache is thoroughly chilled before whipping to achieve a stable, airy consistency. For a milder dessert, you can replace regular coffee with decaffeinated coffee.
