Ingredients

Scale

Pastry Dough

  • 1 cup Pastry Dough (prepared with flour, chilled butter, sugar, eggs, and a pinch of cinnamon)
  • 1/4 tsp Salt

Mousse Filling

  • 8 oz White Chocolate (high-quality recommended)
  • 1 cup Heavy Cream (divided, for heating and whipping)
  • 4 large Egg Yolks
  • 1/4 cup Sugar

Instructions

  1. Pastry Dough Preparation: Blend flour, salt, and a pinch of cinnamon in a bowl. Cut chilled butter into the mixture until it resembles breadcrumbs. Add sugar and mix in eggs until combined. Chill the dough for at least one hour for optimal texture.
  2. Bake Tart Shells: Preheat oven to 190°C (374°F). Roll out chilled dough and carefully fit into tartlet tins. Bake blind with weights for 10 minutes, then remove weights and bake an additional 5 minutes until golden brown. Cool on wire racks.
  3. Mousse Filling Preparation: Beat egg yolks and sugar until light and pale. Gently warm half of the heavy cream, then slowly combine it with the yolk mixture. Return to low heat and stir until thickened. Stir in chopped white chocolate until fully melted. Allow mixture to cool completely.
  4. Whip Cream and Combine: Whip remaining heavy cream to medium-stiff peaks. Gently fold whipped cream into cooled white chocolate mixture until smooth and combined. Refrigerate to allow mousse to firm up.
  5. Assemble Tart: Once tart shells are completely cooled, fill each shell with the white chocolate mousse. Cover and refrigerate for at least 4 hours or overnight to set fully.
  6. Optional Garnish: Before serving, garnish with fresh berries or a drizzle of dark chocolate to add an extra touch of flavor and presentation.

Notes

  • Chill the butter and dough properly for a tender, flaky crust.
  • Use high-quality white chocolate for best flavor and texture.
  • Avoid overwhipping the heavy cream to maintain the ideal mousse consistency.
  • Blind baking the crust ensures a crisp base that won’t become soggy.
  • Refrigerate the assembled tarts well to allow the mousse to set firmly before serving.
  • For added decoration, fresh berries complement the sweetness of the white chocolate beautifully.
