How to Make Rich White Chocolate Mousse Tart
-
Beat eggs: Start by beating the egg yolks and sugar together until the mixture is pale and smooth, creating a luscious base for your mousse.
-
Heat cream: In a double boiler, heat ¼ cup of cream until warm. Combine it with the egg mixture and cook it gently until thickened; this will create a custard-like consistency.
-
Melt chocolate: Pour the warm mixture over chopped real white chocolate. Stir until the chocolate melts completely; allow it to cool slightly before moving on.
-
Whip cream: Whip the remaining heavy cream until you reach medium-stiff peaks. This is key to achieving the airy texture of your mousse!
-
Fold together: Gently fold the whipped cream into the cooled chocolate mixture, combining them without deflating the cream to maintain that lovely lightness.
-
Chill mousse: Transfer the mousse to the refrigerator for a few hours—at least 4 hours for best results—so it sets beautifully.
-
Prepare tart shell:
- Preheat oven: Begin by preheating your oven to 190ºC (374ºF).
- Mix flour: In a food processor, combine flour, salt, cayenne pepper, and cinnamon. Add cold butter and pulse to a crumbly mixture.
- Add eggs and sugar: Pulse in sugar, then add eggs until the dough forms. Chill for 1 hour for best texture.
- Roll and bake: Roll out the dough and fit it into tartlet tins. Bake blind for 10 minutes, then an additional 5 minutes until golden.
- Fill tartlets: Once cooled, carefully fill each tartlet case with the mousse. Top with fresh berries or any optional garnish to elevate your dessert!
Optional: Dust with powdered sugar for an elegant finish.

Make Ahead Options
Preparing the Rich White Chocolate Mousse Tart in advance is a time-saving lifesaver for busy home cooks! You can make the tart shell up to 2 days ahead; just ensure it is completely cooled before storing in an airtight container to maintain its flaky texture. For the mousse, it’s best made the day you plan to serve, but you can prepare it up to 4 hours in advance for it to set. Once ready to serve, fill the cooled tart shell with the chilled mousse and top with fresh berries. This way, you’ll have a stunning dessert that is just as delicious and will allow you to enjoy more time with your guests during your gathering!

Rich White Chocolate Mousse Tart Recipe FAQs
What type of white chocolate should I use?
Absolutely! I recommend using real white chocolate that contains cocoa butter, as it adds richness and flavor. Avoid candy coatings or low-quality chocolate, as they can significantly affect the taste and texture of your mousse.
How should I store the Rich White Chocolate Mousse Tart?
You can store the tart in an airtight container in the refrigerator for up to 3 days. This keeps the mousse fresh and protects it from drying out, allowing you to enjoy its delightful creaminess even after a couple of days!
Can I freeze the mousse tart?
I wouldn’t recommend freezing the filled Rich White Chocolate Mousse Tart. Freezing can create ice crystals in the mousse, affecting its airy texture and making it less enjoyable when thawed. If you have leftover tart shell, though, you can freeze that for up to 3 months before baking.
What if my cream doesn’t whip properly?
Very! If your cream doesn’t whip to medium-stiff peaks, it may be because the cream is too warm or you’ve over-whipped it. Make sure to use cold heavy cream and whip it slowly until you reach the desired consistency. If it turns grainy, you may have gone too far—try starting again with a fresh batch of cream.
Can I use other toppings besides berries?
Absolutely! Feel free to get creative with your toppings! Seasonal fruits, shaved dark chocolate, or a drizzle of raspberry coulis can add an exciting twist to the tart. Choose flavors that complement the mousse for a delightful experience!
Is this dessert suitable for those with egg allergies?
Since this Rich White Chocolate Mousse Tart contains egg yolks for richness, it’s not suitable for those with egg allergies. However, you can experiment with egg substitutes if you’re comfortable! For example, using silken tofu or aquafaba may work as alternatives, but keep in mind the texture and flavor may differ slightly.
