Preheat the oven to 220°C. Line a rimmed baking sheet with parchment paper or a non-stick baking mat.

Combine water, milk, butter, sugar, and salt in a medium saucepan over medium heat. Bring just to the boil, then remove from heat. Add flour all at once and stir vigorously with a wooden spoon until fully incorporated.
03 -
Return the pan to medium heat. Stir constantly for 1.5 to 2 minutes to cook off excess moisture; the dough should form a smooth ball and a thin film will appear on the bottom of the pan.
04 -
Transfer dough to a large mixing bowl. Using an electric mixer at medium speed, beat for 1 minute to release heat.
05 -
Add eggs one at a time, beating thorough each addition until fully integrated. After all eggs are incorporated, beat an extra minute until the batter falls in a thick ribbon from the spoon.

Transfer dough to a piping bag fitted with a 1.25 cm round tip. Pipe 28 puffs, each approximately 3.5 cm in diameter and 1 cm high, spaced 2.5 cm apart. If peaks form, lightly wet your fingertip and smooth them down.

Bake in the oven at 220°C for 10 minutes. Without opening the oven, reduce the temperature to 160°C and bake for an additional 20 to 22 minutes until golden brown. Transfer puffs to a wire rack and allow to cool completely.
08 -
In a large bowl, combine chilled heavy cream, sugar, and vanilla extract. Beat on medium-high speed for about 2 minutes until stiff peaks form. Transfer the whipped cream to a piping bag fitted with a large open star tip.
09 -
Once puffs are completely cool, fill each with whipped cream by either piping into the side or cutting off the tops and filling. If desired, nestle one raspberry inside each puff before replacing the top.
