There’s something wonderfully enchanting about the way a simple treat can elevate a moment. Picture this: it’s a balmy summer evening, and friends have gathered on the patio, laughter mingling with the smell of blooming flowers. As the sun dips below the horizon, the light warms everything in a soft glow. On the table sits a tray of tiny white chocolate mousse tartlets, each one a delicate little promise of sweet bliss. I can remember the first time I made these lovelies; I was ready to tackle something fancy, but I wanted to keep it simple. These tartlets came to life from that playful spirit—easy yet impressive. And let me tell you, they absolutely stole the show!

Ingredients You’ll Need
- For the Tart Shells:
- 1 ½ cups all-purpose flour: The base of your tart, giving it that classic pastry texture.
- ½ cup unsalted butter, chilled and cubed: Creates a flaky, tender shell that crumbles just right.
- ¼ cup powdered sugar: Adds just the right amount of sweetness to the crust.
- 1 egg yolk: Helps bind the dough together, making it easier to work with.
- 2-3 tablespoons cold water: A touch to bring the dough together without overworking it.
- For the Mousse:
- 7 oz. white chocolate, chopped: The star of the show, lending its creamy sweetness.
- 2 cups heavy whipping cream: Whipped to soft peaks for that luxurious texture.
- 3 egg whites: Whipped until frothy for added lightness and volume.
- ¼ cup granulated sugar: Helps to stabilize the egg whites while adding sweetness.
- 1 teaspoon vanilla extract: Just a splash to deepen the flavor.
Optional Additions
- Fresh berries (strawberries or raspberries): Tossing a few atop the mousse provides a burst of acidity and color.
- Mint leaves: For a refreshing finish that also looks oh-so-pretty.
- Dark chocolate shavings: Consider these a delightful contrast to the sweet white chocolate.
Special Garnishes
- Dust with cocoa powder or powdered sugar to add a touch of elegance.
- Drizzle with a chocolate sauce for a decadently rich presentation.

Step-by-Step Instructions
Now, let’s roll up our sleeves and get started—trust me, this is where the magic begins!
- Make the Tart Shells:
In a mixing bowl, combine the flour and powdered sugar. Add in the chilled butter, and use your fingers or a pastry cutter to mix it until the mixture resembles coarse crumbs. This step is fun—don’t be afraid to get your hands messy!
- Add Egg and Water:
Mix in the egg yolk and just enough cold water until the dough comes together. It should be slightly tacky but not sticky. Wrap it in plastic wrap and chill it in the fridge for about 30 minutes.
- Preheat the Oven:
While the dough is chilling, preheat your oven to 375°F (190°C). Your kitchen will start to smell heavenly soon!
- Roll Out the Dough:
Once chilled, roll out the dough on a floured surface. Cut into circles to fit your tartlet pans. Press them gently into the molds, then poke small holes in the bottom with a fork to prevent bubbling.
- Bake Them Up:
Bake the tart shells for about 15-20 minutes, or until lightly golden. Let them cool for a few minutes before gently removing them from the pans.
- Prepare the Mousse:
While the tart shells cool, melt the white chocolate over a double boiler, stirring until smooth. Allow it to cool slightly while you whip the cream and egg whites.
- Whip It Good:
In a bowl, whip 1 cup of the heavy cream until soft peaks form. In another bowl, whisk the egg whites until frothy, then gradually add granulated sugar, whipping until stiff peaks form. Stir a small portion of the whipped cream into the melted chocolate until combined.
- Combine and Fold:
Gently fold in the remaining whipped cream and then the whipped egg whites until no white streaks remain. Don’t rush this step; it’s where your mousse becomes light and dreamy!
- Fill the Tartlets:Pipe or spoon the mousse into your cooled tart shells. A piping bag can make this feel even more special, but if you don’t have one, don’t worry! A simple spoon works just as well.
- Chill:Refrigerate the tartlets for at least 2 hours to allow them to set. Use this time to clean up, or perhaps pour yourself a glass of something lovely!
Recipe Variations
Feeling adventurous? Switch things up! You could infuse the white chocolate mousse with citrus zest—lemon or orange would be delightful for a fresh twist. If you’re not a fan of white chocolate, feel free to swap it out for milk or dark chocolate for a richer dessert. Want to play with presentation? Serve the mousse in mini glasses instead of tart shells for a trendy parfait look!
Serving & Storage Tips
These tartlets are best enjoyed fresh, but don’t fret if you have leftovers! They’ll keep well in an airtight container in the fridge for up to three days. I suggest enjoying them cold but let them sit out for a few minutes before serving—this will soften the mousse slightly, enhancing that melt-in-your-mouth experience.
Helpful Tips
Okay, let’s avert potential mishaps here! First, be gentle when folding the egg whites; those little bubbles are what give your mousse that airy lift. Also, make sure your cream is chilled when whipping for the best results. If you overbake the tart shells, they could become too hard—aim for a light golden hue. And trust me on this: the longer you chill the tartlets, the better they’ll be! Patience is a virtue here, my amigos.
Special Equipment
- Food Processor: Makes pie dough so much easier (and less messy!). Plus, it saves your upper arms from unnecessary workout!
- Piping Bag or Ziplock Bag: For fuss-free filling of the mousse into the tart shells—elegant and adorable.
- Tartlet Pan: These little guys come in all shapes and sizes. Using one ensures you get beautifully shaped tartlets every time.

Frequently Asked Questions
Can I make these tartlets ahead of time?
Absolutely! You can prepare the tart shells a day in advance and fill them with mousse the day you plan to serve them. Just keep everything covered in the fridge.
Can I use a different type of chocolate?
Sure! While this recipe shines with white chocolate, feel free to use milk or dark chocolate for a different flavor profile. Just remember to adjust the sugar based on the chocolate’s sweetness!
How do I know when the mousse is set?
The mousse will firm up in the fridge, but you’ll know it’s ready when it holds its shape and feels light and airy when you give it a gentle touch.
