Ingredients

Scale
  • 1 1/4 cups (160g) all-purpose flour
  • 1/4 cup (50g) granulated sugar
  • 1/2 cup (115g) unsalted butter, cold and cubed
  • 1 large egg yolk, room temperature
  • 1–2 tablespoons ice water
  • Pinch of salt
  • 7 oz (200g) good-quality white chocolate
  • 1 cup (240ml) heavy cream, cold
  • 1 teaspoon vanilla bean paste or pure vanilla extract
  • 1 tablespoon powdered sugar (optional)
  • Optional garnishes: fresh berries (raspberries or strawberries), edible flowers, white chocolate shavings

Instructions

  1. Make the Tart Dough: In a food processor, pulse together flour, sugar, and salt until combined. Add cold, cubed butter and pulse until mixture resembles coarse crumbs with pea-sized bits. Add egg yolk and 1 tablespoon ice water, pulsing just until dough comes together. Add more water if needed. Form dough into a disk, wrap in plastic, and chill for at least 30 minutes.
  2. Preheat Oven and Prepare Tart Pans: Heat oven to 350°F (175°C). Lightly butter tartlet pans or spray with nonstick spray.
  3. Roll Out and Shape: On a lightly floured surface, roll dough to about 1/8-inch thickness. Cut rounds slightly larger than tartlet pans. Press dough into pans, trim edges, and prick bottoms with a fork.
  4. Bake the Tart Shells: Line each shell with parchment and fill with pie weights or dried beans. Bake 12-15 minutes, remove weights and parchment, then bake another 5-7 minutes until golden and crisp. Cool completely on wire rack.
  5. Melt White Chocolate: Chop white chocolate finely. Melt gently using double boiler or heatproof bowl over simmering water, stirring often. Remove from heat and cool slightly.
  6. Whip the Cream: In a chilled bowl, whip heavy cream until soft peaks form. Add powdered sugar (optional) and vanilla bean paste, whip until just combined but still soft.
  7. Combine Chocolate and Cream: Stir about 1/4 of whipped cream into melted chocolate to lighten. Gently fold in remaining whipped cream in two additions, keeping mixture airy and smooth.
  8. Fill Tart Shells: Spoon or pipe mousse into cooled tart shells evenly. Smooth tops with spatula if needed.
  9. Chill: Refrigerate tartlets for at least 2 hours or until mousse is set and firm to touch.
  10. Garnish and Serve: Just before serving, add fresh berries or chocolate shavings.

Notes

Melt white chocolate slowly to prevent graininess; if clumpy, stir in a teaspoon of warm cream. Whip cream to soft peaks only to keep mousse light and airy. Blind bake tart shells with weights to keep crust crisp. Chill mousse tartlets at least 2 hours for best texture. Piping mousse helps keep neat layers. Tart shells can be baked up to 3 days ahead and stored airtight at room temperature. For gluten-free, substitute almond flour; for dairy-free, use coconut cream and dairy-free white chocolate.
