Ingredients

Scale

Crust

  • 1 1/4 cups (150g) all-purpose flour
  • 1/4 cup (30g) powdered sugar
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1/2 cup (113g) cold unsalted butter, cubed
  • 1 large egg yolk
  • 1–2 tablespoons cold water

Mousse Filling

  • 8 ounces (225g) high-quality white chocolate, chopped
  • 1 cup (240ml) heavy cream, chilled
  • 1/4 cup (60ml) milk (whole or 2%)
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon unflavored gelatin (optional, for extra stability)

Decoration

  • Fresh raspberries, strawberries, or blueberries
  • White chocolate curls or shavings
  • Mint leaves for garnish
  • Light dusting of powdered sugar

Instructions

  1. Prepare Dry Ingredients: In a large mixing bowl, whisk together the flour, powdered sugar, cinnamon, nutmeg, and salt to ensure even distribution of spices.
  2. Incorporate Butter: Add the cold cubed unsalted butter to the dry mixture. Use a pastry cutter or your fingertips to rub the butter into the flour until it resembles coarse crumbs.
  3. Add Egg and Water: Mix in the egg yolk and 1 tablespoon cold water gently with a fork. Add more water if needed until the dough holds together when pinched.
  4. Chill Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes to rest and firm up.
  5. Preheat Oven: Set the oven to 350°F (175°C) to prepare for baking the crust.
  6. Roll Out Dough: On a lightly floured surface, roll the chilled dough to fit a 9-inch tart pan with removable bottom.
  7. Line Tart Pan: Press the dough gently into the tart pan and trim excess from edges. Prick the base with a fork to prevent bubbling.
  8. Blind Bake: Line the crust with parchment paper and fill with pie weights or dried beans to maintain shape. Bake for 15 minutes.
  9. Finish Baking Crust: Remove parchment paper and weights, then bake an additional 10 minutes until golden brown. Let cool completely on a wire rack.
  10. Prepare Gelatin (Optional): If using, sprinkle gelatin over 1 tablespoon cold water in a small bowl and let it bloom for 5 minutes.
  11. Heat Milk and Dissolve Gelatin: Warm the milk in a small saucepan until just simmering without boiling. Remove from heat and stir in bloomed gelatin until completely dissolved.
  12. Melt White Chocolate: Add chopped white chocolate to warm milk. Let rest for a minute, then stir until smooth and fully melted.
  13. Add Vanilla and Cool: Stir in vanilla extract and let the mixture cool to room temperature.
  14. Whip Cream: In a large bowl, use a hand mixer to beat chilled heavy cream to soft peaks.
  15. Fold Cream into Chocolate Mixture: Gently fold the whipped cream into the white chocolate mixture in batches to maintain a light, airy mousse texture.
  16. Fill Tart Shell: Spoon or pour the mousse into the cooled tart crust and smooth the top evenly with a spatula.
  17. Chill Mousse: Refrigerate the tart for at least 4 hours until mousse is fully set and firm to the touch.
  18. Decorate: Before serving, garnish the tart with fresh berries, white chocolate curls, mint leaves, and a light dusting of powdered sugar.
  19. Serve: Slice the tart using a warm knife for clean cuts and serve chilled for the best texture and flavor.

Notes

  • The gelatin is optional but helps stabilize the mousse for cleaner slices.
  • Use high-quality white chocolate for the best flavor and smoothness.
  • Blind baking the crust prevents sogginess once the mousse is added.
  • Chilling the crust and mousse properly is essential to achieving the ideal texture.
  • To easily remove the tart from the pan, use one with a removable bottom.
  • Ensure the cream is well chilled before whipping to achieve best volume and texture.
