White Chocolate Mousse Tarts

Published: by . Leave a Comment

When we want to feel a little fancy without spending all day in the kitchen, we make these White Chocolate Mousse Tarts. Max calls them "snowy fruit baskets" because of the fluffy white filling and the mountain of berries on top. They look like something you’d pay a fortune for at a French patisserie, but they are secretly easy to assemble at home. The combination of the buttery crisp shell, the airy sweet mousse, and the tart fresh fruit is absolute perfection.

Why You Will Love This White Chocolate Mousse Tart

You will love this recipe because it is the definition of "low effort, high reward." The filling is a simple but luxurious whipped white chocolate mousse that requires no baking. The visual appeal is stunning—the vibrant reds and blues of the raspberries and blueberries pop against the creamy white filling, while the white chocolate shards add a modern geometric touch. It’s the perfect dessert for a tea party, a bridal shower, or just a Tuesday night when you need a treat.

How To Make White Chocolate Mousse Tart

To recreate the exact look in the picture, we start with a golden, fluted tart shell (you can bake them or buy high-quality pre-made ones). We fill them with a piped swirl of white chocolate mousse. Then comes the fun part: piling on the toppings. We use fresh raspberries, strawberry slices, and glossy blueberries, tucking in thin squares of white chocolate and fresh mint leaves for color. A final dusting of powdered sugar makes them look magical.

White Chocolate Mousse Tart Ingredients

The Tart Shell

  • 1 ½ cups all-purpose flour
  • ½ cup unsalted butter; cold and cubed
  • ¼ cup powdered sugar
  • 1 egg yolk
  • 1 tablespoon ice water

The White Chocolate Mousse

  • 6 oz high-quality white chocolate (bar is better than chips); chopped
  • 1 ½ cups heavy whipping cream; divided
  • 1 teaspoon vanilla extract/paste

The Garnish

  • Fresh raspberries, blueberries, and strawberries (sliced)
  • White chocolate bar (shaved into squares or shards)
  • Fresh mint leaves
  • Powdered sugar (for dusting)

Step by Step Method

Make the Crust

  • Pulse flour, sugar, and cold butter in a food processor until it looks like crumbs. Add the egg yolk and water, pulsing until dough forms.
  • Press the dough into mini tart pans (fluted edges look best). Prick the bottom with a fork.
  • Bake at 375°F (190°C) for 12–15 minutes until golden brown. Let them cool completely.

Make the Mousse Base

  • Place the chopped white chocolate in a heatproof bowl.
  • Heat ½ cup of the heavy cream until just simmering (do not boil). Pour over the chocolate and let sit for 2 minutes.
  • Whisk gently until smooth and glossy. Stir in the vanilla. Let this ganache cool to room temperature (it must not be hot!).

Whip the Mousse

  • Whip the remaining 1 cup of cold heavy cream to soft peaks.
  • Gently fold the cooled white chocolate mixture into the whipped cream until combined and fluffy.
  • Transfer to a piping bag fitted with a large star tip.

Assemble

  • Pipe a generous swirl of mousse into each cooled tart shell.
  • Arrange the fruit on top—don't be shy, pile it high! Use whole raspberries and cut strawberries.
  • Tuck in the white chocolate squares and mint leaves.
  • Just before serving, dust lightly with powdered sugar.

MAX’S REACTION

"I like the white chocolate squares the best! They crunch when you bite them. The cream is super sweet but the berries make it sour in a good way. I call this a 'Princess Pie'!"

What Pairs Well With White Chocolate Mousse Tart

These tarts are rich, so they pair beautifully with a hot cup of Earl Grey tea or a glass of chilled champagne. If you are serving them at a brunch, a tart mimosa or a sparkling lemonade helps cut through the sweetness of the white chocolate.

White Chocolate Mousse Tart Variations

No Bake Hack

To make this a true No Bake Dessert, use store-bought mini tart shells or phyllo cups. You can also make a no-bake crust using crushed shortbread cookies and butter.

Dark Chocolate

Swap the white chocolate for dark chocolate in the mousse and top with cherries and blackberries for a moody, decadent version.

Lemon Lovers

Spread a thin layer of lemon curd at the bottom of the tart shell before piping in the mousse. The citrus adds a bright surprise.

Mini Bites

Make these in a mini muffin tin using cookie dough cups for bite-sized Mini Tart Recipes perfect for passing around at parties.

Equipment

  • Mini Tart Pans (4-inch size with removable bottoms are best)
  • Food Processor (for crust)
  • Electric Mixer
  • Piping Bag and Star Tip
  • Mom Tip: If you don't have tart pans, you can use the back of a muffin tin to shape your dough cups!

Storage / Make Ahead / Serving Tips

Make Ahead

You can bake the tart shells up to 2 days in advance (store in an airtight container). The mousse can be made a day ahead and kept in the fridge.

Assembly

Assemble the tarts no more than 2–3 hours before serving. If they sit too long, the moisture from the mousse can make the crust soggy.

Refrigerator Storage

Store leftovers in the fridge for up to 2 days. The fruit may start to "weep" juices, so they are definitely best eaten fresh.

Top Tips for Best White Chocolate Mousse Tart

White chocolate can be finicky! Make sure you use a high-quality bar (like Ghirardelli or Lindt) rather than chips, which often contain stabilizers that prevent smooth melting. Also, ensure your fruit is completely dry after washing before placing it on the mousse, or the colors might bleed into the white cream.

White Chocolate Mousse Tart FAQs

Why is my mousse grainy?

This usually happens if the white chocolate was too hot when added to the whipped cream. Make sure the chocolate mixture is cool to the touch before folding.

Can I use frozen fruit?

No, frozen fruit releases too much water when thawing and will ruin the look and texture. Stick to fresh berries.

Is this gluten-free?

The filling is GF, but you need to use a gluten-free flour blend or a nut-based crust (like almond flour) for the shell.

Can I use cream cheese?

Yes! You can beat 4 oz of softened cream cheese into the white chocolate mixture for a sturdier, cheesecake-like mousse.

A Fancy Finish

These tarts are the ultimate way to end a meal on a high note. They are delicate, beautiful, and delicious.
