White Chocolate Mousse Tartlets Ingredients

For the Mousse
Egg Yolks – Adds richness and helps with mousse structure.
Granulated Sugar – Provides sweetness and balances flavors.
Heavy Cream – Creates the light, airy texture of the mousse; aim for full-fat (36% or higher) for best results.
Real White Chocolate (Ghirardelli, Lindt, or Callebaut) – Core flavor of the mousse; must contain cocoa butter for smooth texture.

For the Crust
All-Purpose Flour – Forms the base of the tart crust; can be substituted with a 1:1 gluten-free blend.
Unsalted Butter – Essential for creating a tender pastry; using unsalted helps control the saltiness.
Sugar (for crust) – Sweetens the crust; works with other ingredients to enhance flavor.
Eggs + Extra Egg Yolk – Adds moisture and richness to the dough.
Salt – Enhances flavor.
Cayenne Pepper – Provides a subtle heat; can be omitted if desired.
Cinnamon – Adds warmth and depth to the crust flavor.

Step‑by‑Step Instructions for White Chocolate Mousse Tartlets

Step 1: Make the Mousse
Start by beating 4 egg yolks and 1/2 cup of granulated sugar in a mixing bowl until the mixture is light and pale, which should take about 3 minutes. In a double boiler, heat 1 cup of heavy cream until just warm, then slowly pour it over the egg mixture, stirring constantly until it thickens—this should take around 5 minutes. Remove from heat and mix in 8 oz of chopped real white chocolate until melted and smooth. Allow it to cool.

Step 2: Prepare Pastry Dough
Preheat your oven to 190ºC (374ºF). In a food processor, combine 1 1/2 cups of all-purpose flour, a pinch of salt, a quarter teaspoon of cayenne pepper, and one teaspoon of cinnamon; pulse the mixture until well mixed. Add 1/2 cup of unsalted butter, cut into cubes, and process until crumbly. Follow with 1/4 cup of sugar, one whole egg, and one extra yolk, pulsing until a cohesive dough forms.

Step 3: Chill & Roll Dough
Once your dough is formed, wrap it in parchment paper and refrigerate for at least 1 hour, allowing it to become firm. After chilling, roll out the dough on a lightly floured surface until it’s about 1/8 inch thick. Use a round cutter to cut out shapes that fit your tartlet tins, ensuring you have enough dough for all of them.

Step 4: Blind Bake
Preheat your oven to 190ºC (374ºF) if you haven’t already. Line each tartlet shell with parchment paper, filling them with pie weights or dried beans to prevent bubbling. Bake for 10 minutes, then carefully remove the weights and parchment. Return them to the oven for an additional 5 minutes, or until they’re golden brown, then let them cool completely on a wire rack.

Step 5: Assemble
Once the tartlet shells are fully cooled, gently spoon the prepared white chocolate mousse into each shell, smoothing the tops with a spatula. Allow the mousse to set in the refrigerator for at least 2 hours before serving to achieve the best texture. Optionally, garnish your White Chocolate Mousse Tartlets with fresh fruit or a delicate dusting of cinnamon and icing sugar for an extra touch of elegance.

How to Store and Freeze White Chocolate Mousse Tartlets

Fridge: Store assembled tartlets in an airtight container in the refrigerator for up to 2-3 days to maintain freshness and flavor.

Freezer: It’s best not to freeze the assembled tartlets, as the mousse may lose its creamy texture upon thawing. Instead, freeze the tartlet shells for up to 1 month, then fill with mousse before serving.

Making Ahead: Consider preparing the mousse a day in advance and refrigerating it separately. Assemble the tartlets just before serving for the best presentation and taste.

Reheating: If you’ve made a batch of tartlet shells, simply thaw them at room temperature before filling with mousse; do not bake again.

Make Ahead Options

These White Chocolate Mousse Tartlets are perfect for busy home cooks looking to save time! You can prepare the white chocolate mousse up to 3 days in advance; simply refrigerate it in an airtight container to maintain its creamy texture. Additionally, the tartlet shells can be made up to 24 hours prior—just be sure to store them in an airtight container to avoid moisture. When you’re ready to serve, spoon the chilled mousse into the cooled tartlet shells and let them set in the refrigerator for about 2 hours for the best results. With this prep, you’ll have a stunning dessert that’s just as delicious without the last-minute rush!

Expert Tips for White Chocolate Mousse Tartlets

White Chocolate Mousse Tartlets Recipe FAQs

What kind of white chocolate should I use for the mousse?
Absolutely! I recommend using high-quality white chocolate bars, such as Ghirardelli, Lindt, or Callebaut. These brands contain cocoa butter, which gives the mousse a silky texture and rich flavor. Avoid chocolate chips, as they often contain stabilizers that prevent smooth melting.

How should I store the assembled tartlets?
To keep your scrumptious White Chocolate Mousse Tartlets fresh, store them in an airtight container in the refrigerator. They’ll maintain their delightful taste and texture for up to 2-3 days. Be sure to let them sit at room temperature for a few minutes before serving to savor the full flavors.

Can I freeze the tartlet shells?
Yes, you can! It’s best not to freeze the assembled tartlets themselves, as the mousse can get gritty once thawed. Instead, freeze the tartlet shells separately for up to 1 month. When you’re ready to enjoy, thaw at room temperature and fill them with the mousse right before serving for optimal taste and texture.

What if my mousse doesn’t set properly?
Very! If you find that your mousse is too runny, it may be due to under-whipping the cream or not allowing the mousse to chill long enough. Ensure that the heavy cream is fully whipped to stiff peaks before folding it into the chocolate mixture. If it’s still too soft, you can gently rewarm the mousse mixture and add a little extra melted white chocolate to help firm it up.

Can I adjust the spices in the crust for a different flavor?
Definitely! You can swap cayenne for black pepper for a different kick or leave it out entirely for a milder flavor. If you’re a fan of warm spices, consider adding a pinch of nutmeg or some grated ginger for an exotic twist. Taste-testing along the way makes the process enjoyable and personal!
