Step‑by‑Step Instructions for Dark Chocolate Peppermint Mousse Tart
Step 1: Preheat and Prepare the Crust
Preheat your oven to 350°F (175°C). In a medium bowl, combine 1 ½ cups of chocolate cookie crumbs, ½ cup of melted unsalted butter, and 2 tablespoons of granulated sugar. Stir well until the mixture resembles wet sand. This will form the delicious crust for your Dark Chocolate Peppermint Mousse Tart.
Step 2: Bake the Crust
Press the cookie mixture evenly into the bottom and up the sides of a 9-inch tart pan, creating a solid base. Bake for 10 minutes, or until slightly firm. The crust should look set and fragrant. Once finished, remove it from the oven and allow it to cool completely on a wire rack before filling.
Step 3: Melt the Dark Chocolate
In a microwave-safe bowl, add 8 ounces of chopped dark chocolate. Heat in the microwave in 30-second intervals, stirring frequently until smooth and fully melted. This may take about 1 to 1.5 minutes total. Allow the melted chocolate to cool slightly while you prepare the whipped cream.
Step 4: Whip the Cream
In a separate bowl, pour 1 cup of heavy cream. Using an electric mixer, whip the cream on medium speed until soft peaks form, which will take about 3-4 minutes. The cream should hold its shape but still be smooth and creamy. Once done, gently fold this whipped cream into the melted chocolate until no streaks remain, creating a delightful mousse.
Step 5: Beat the Egg Whites
In another clean bowl, beat 3 large egg whites with a pinch of salt using an electric mixer. Beat until medium peaks form, and then gradually add ¼ cup of granulated sugar. Continue to beat until the mixture reaches stiff peaks, about 3-5 minutes. The egg whites should be glossy and firm, creating a light texture for your mousse.
Step 6: Combine Mousse Ingredients
Gently fold the beaten egg whites into the chocolate mixture in thirds. Use a spatula to combine, being careful not to deflate the airiness from the egg whites. This step is crucial for achieving that light, fluffy texture in your Dark Chocolate Peppermint Mousse Tart.
Step 7: Add the Peppermint Extract
Once the egg whites are fully incorporated, add ½ teaspoon of peppermint extract to the mousse. Fold gently until the peppermint is evenly distributed throughout the mixture. This addition will bring a refreshing touch that perfectly complements the rich dark chocolate.
Step 8: Fill the Tart Shell
Spoon the mousse mixture into the cooled tart shell, spreading it evenly. Use a spatula to smooth the top for a polished finish. The mousse should be luscious and rich, filling the crust beautifully, setting the stage for your tantalizing dessert.
Step 9: Chill the Tart
Cover the tart with plastic wrap and refrigerate for at least 4 hours, or until the mousse is set. This chilling time allows the flavors to meld beautifully and ensures a firm texture that is perfect for slicing.
Step 10: Prepare to Serve
Shortly before serving, whip the remaining 1 cup of heavy cream in a bowl until peaks form. Spread the whipped cream over the top of the chilled mousse tart. This will create a delightful contrast to the rich chocolate and peppermint flavors.
Step 11: Garnish and Present
Finally, sprinkle crushed peppermint candies and shaved chocolate or chocolate curls over the whipped cream. This final touch adds a festive flair and a delightful crunch to your Dark Chocolate Peppermint Mousse Tart, making it an eye-catching centerpiece.

Expert Tips for Dark Chocolate Peppermint Mousse Tart
Use Quality Chocolate: Choose good-quality dark chocolate with at least 70% cacao for rich flavor and a silky texture in your mousse.
Chill the Egg Whites: For fluffier results, make sure your egg whites are at room temperature; this helps achieve better volume when beaten.
Gentle Folding: When mixing the chocolate and egg whites, be gentle to avoid deflating the airiness—this keeps your Dark Chocolate Peppermint Mousse Tart light and luscious.
Proper Cooling Time: Ensure your tart crust cools completely before adding the mousse to prevent melting and sogginess.
Chill Long Enough: Don’t rush the chilling process—allowing at least 4 hours helps the mousse set perfectly and enhances the flavor profile.
With these tips, you're all set to create a stunning Dark Chocolate Peppermint Mousse Tart that will impress everyone at your table!
How to Store and Freeze Dark Chocolate Peppermint Mousse Tart
Fridge: Store the tart in an airtight container in the refrigerator for up to 5 days. This will keep the mousse fresh and creamy while preventing it from absorbing any odors.
Freezer: For longer storage, freeze slices wrapped tightly in plastic wrap and then in foil for up to 2 months. To serve, thaw overnight in the fridge before indulging.
Reheating: There’s no need to bake again; simply enjoy your tart cold. If it feels too firm, let it sit at room temperature for about 15 minutes to soften slightly before serving.
Garnishing Instructions: If you’ve added garnishes, like whipped cream, it’s best to store them separately to retain freshness. Add the toppings right before serving for the best texture and appearance.
Make Ahead Options
These Dark Chocolate Peppermint Mousse Tarts are perfect for meal prep enthusiasts! You can prepare the crust up to 24 hours in advance by baking it and storing it at room temperature, tightly wrapped to maintain its crispness. Additionally, you can make the mousse mixture and refrigerate it for up to 3 days before filling the tart shell. When you're ready to serve, simply spoon the chilled mousse into the cooled crust, smooth the top, and refrigerate for at least 4 hours or until set. To finish, whip the remaining heavy cream and top with crushed peppermint candies and chocolate shavings right before serving for that just-made taste. This strategy helps save time and ensures your tart remains just as delicious!

Dark Chocolate Peppermint Mousse Tart Recipe FAQs
How do I choose the best dark chocolate for this tart?
Absolutely! For the best flavor and texture, opt for dark chocolate with at least 70% cacao content. This ensures a rich, intense chocolate flavor that complements the sweetness of the mousse. Look for high-quality brands, as they generally have fewer additives and better taste.
What is the best way to store the Dark Chocolate Peppermint Mousse Tart?
For sure! Store the tart in an airtight container in the refrigerator for up to 5 days. This keeps the mousse fresh and creamy, while also preventing it from picking up any unwanted odors from your fridge.
Can I freeze the Dark Chocolate Peppermint Mousse Tart?
Yes, you can! To freeze, wrap individual slices tightly in plastic wrap, then cover them with aluminum foil. This method helps protect them from freezer burn. The tart can be kept frozen for up to 2 months. To enjoy, simply thaw it overnight in the refrigerator before serving.
What should I do if my mousse doesn't set properly?
No worries! If your mousse doesn’t set after chilling for 4 hours, it might be due to under-beaten egg whites or not folding them in gently enough. Make sure to beat your egg whites until stiff peaks form, and when folding them into the chocolate mixture, do so delicately to maintain airiness. If all else fails, try chilling the tart for a bit longer, as sometimes patience is key!
Is this tart suitable for those with allergies?
Great question! This tart contains egg whites, heavy cream, and chocolate, which could pose issues for those with dairy or egg allergies. For a dairy-free option, use coconut cream or dairy-free whipped cream. Just double-check the chocolate label to ensure it’s dairy-free as well.
How long can I keep leftovers?
Leftovers can be stored in the fridge for 3 to 4 days in an airtight container. Just remember to keep any garnishes, like whipped cream and peppermint candies, separate so they stay fresh and don't affect the mousse's texture. Enjoy every last bite!
