Step-by-Step Instructions
For the Tart Shell:
- In a food processor, pulse together the all-purpose flour, confectioners’ sugar, and salt until well combined.
- Add the chilled, cubed unsalted butter to the food processor. Pulse until the mixture resembles coarse crumbs with some pea-sized pieces of butter remaining.
- In a small bowl, whisk together the egg yolk and 2 tablespoons of ice water.
- With the food processor running, drizzle in the egg yolk mixture until the dough just begins to come together. If the dough seems too dry, add another tablespoon of ice water, one teaspoon at a time, until it forms a cohesive ball. Be careful not to overmix.
- Turn the dough out onto a lightly floured surface and gently shape it into a flat disc. Wrap the disc tightly in plastic wrap and refrigerate for at least 30 minutes, or up to 2 days.
- Preheat your oven to 375°F (190°C).
- Remove the chilled dough from the refrigerator. On a lightly floured surface, roll out the dough into a 12-inch circle, about ¼ inch thick.
- Carefully transfer the rolled-out dough to a 9-inch tart pan with a removable bottom. Gently press the dough into the bottom and up the sides of the pan, trimming any excess dough from the edges.
- Prick the bottom of the tart shell all over with a fork.
- Line the tart shell with parchment paper and fill with pie weights or dried beans.
- Bake for 15 minutes. Remove the parchment paper and weights, and continue to bake for another 10-12 minutes, or until the shell is lightly golden brown.
- Let the tart shell cool completely on a wire rack before filling.
For the White Chocolate Mousse:
- Place the finely chopped white chocolate in a heatproof bowl. Set aside.
- In a small saucepan, heat ½ cup of the heavy cream over medium heat until it just begins to simmer. Do not boil.
- Pour the hot cream over the chopped white chocolate. Let it sit for 1-2 minutes, then whisk gently until the chocolate is completely melted and smooth. Set aside to cool slightly.
- In a separate medium bowl, whisk together the egg yolks, granulated sugar, and salt until pale yellow and slightly thickened.
- In another small saucepan, heat the remaining 1 cup of heavy cream over medium heat until it just begins to simmer.
- Slowly temper the egg yolk mixture by gradually whisking about half of the hot cream into the egg yolks.
- Pour the tempered egg yolk mixture back into the saucepan with the remaining hot cream. Cook over low heat, stirring constantly with a wooden spoon or spatula, until the mixture thickens enough to coat the back of the spoon (about 5-7 minutes). Do not let it boil, or the eggs will scramble.
- Remove the pastry cream from the heat and immediately strain it through a fine-mesh sieve into the bowl with the melted white chocolate.
- Whisk the melted white chocolate and strained pastry cream together until smooth and well combined. Stir in the vanilla extract.
- Let the white chocolate mixture cool at room temperature until it starts to thicken slightly, about 15-20 minutes. Stir occasionally.
- Once cooled and slightly thickened, gently fold in the remaining ½ cup of heavy cream (whipped to soft peaks, if desired, for a lighter mousse, or use as is for a denser mousse). Be careful not to overmix, as you want to keep the mousse light and airy.
Assembling the Tart:
- Pour the white chocolate mousse into the cooled tart shell, spreading it evenly with an offset spatula.
- Cover the tart loosely with plastic wrap, ensuring the plastic wrap does not touch the surface of the mousse.
- Refrigerate for at least 4 hours, or preferably overnight, until the mousse is set.
Garnishing:
- Once the mousse is set, carefully remove the sides of the tart pan.
- Garnish the Elegant White Chocolate Mousse Tart with fresh berries, white chocolate shavings, and mint sprigs as desired.

Storing and Reheating Tips
- Storage: Leftover Elegant White Chocolate Mousse Tart should be stored in the refrigerator. Cover the tart loosely with plastic wrap or transfer any slices to an airtight container.
- Freshness: The tart will stay fresh in the refrigerator for up to 3 days. The mousse may become slightly denser the longer it sits, but its flavor will remain excellent.
- Reheating: This tart is best served chilled and does not require reheating. If you prefer a slightly softer mousse, you can let a slice sit at room temperature for about 10-15 minutes before serving.
- Freezing: While the mousse texture can be slightly altered upon thawing, you can freeze the assembled tart (before garnishing). Once set, cover it very tightly with plastic wrap and then aluminum foil. For best results, thaw overnight in the refrigerator before garnishing and serving.
