How to Make White Chocolate Mousse Tartlets
Step 1: Prepare the Tart Shells
- Preheat your oven to 350°F (175°C).
- In a mixing bowl, combine flour, powdered sugar, and salt.
- Add cold butter cubes and rub into the flour mixture until it resembles fine breadcrumbs.
- Add egg yolk and cold water gradually, mixing until dough comes together.

Step 2: Prepare the White Chocolate Mousse
- Melt the white chocolate gently using a double boiler or microwave in short bursts. Let it cool slightly.
- Whip the heavy cream with sugar and vanilla until soft peaks form.

- Gently fold in the remaining whipped cream until smooth and fully incorporated.
Step 3: Assemble the Tartlets
- Spoon or pipe the mousse into cooled tart shells.
- Chill in the refrigerator for at least 2–3 hours, allowing the mousse to set.
