Dark Chocolate Peppermint Mousse Tart Ingredients
For the Crust
• Chocolate Graham Crackers – These provide a delicious, sweet base; feel free to swap for an Oreo crust if you prefer.
• Melted Butter – Binds the crust ingredients together; use unsalted for the best flavor.
• Sugar – Adds sweetness to the crust, enhancing the overall taste.
For the Mousse
• Unflavored Gelatin – This ingredient keeps the mousse stable; agar-agar can be used for a vegetarian option, though it may change the texture.
• Cold Water – Activates the gelatin effectively.
• White Chocolate Chips – They provide a creamy sweetness; consider a non-dairy alternative if needed.
• Milk, Half and Half, or Cream – Adds rich creaminess to the mousse; choose whichever you have on hand.
• Powdered Sugar – Sweetens the whipped cream to perfection in the mousse.
• Heavy Whipping Cream – Ensures a light and airy texture; make sure it’s very cold before whipping.
• Pure Peppermint Oil – Infuses the mousse with a refreshing mint flavor; adjust quantities to suit your taste.
For the Glaze
• Bittersweet or Dark Chocolate – This forms the shiny glaze; opt for high-quality chocolate (70% cacao recommended) for the best outcome.
• Light Corn Syrup – Provides a lovely shine to the glaze; can be skipped, but might affect glossiness.
• Very Warm Water – Helps to dissolve the glaze ingredients smoothly.
This impressive Dark Chocolate Peppermint Mousse Tart is sure to be a show-stopping holiday dessert that everyone will adore!
Step‑by‑Step Instructions for Dark Chocolate Peppermint Mousse Tart
Step 1: Prepare the Chocolate Crust
Preheat your oven to 350°F (175°C). In a mixing bowl, combine finely ground chocolate graham crackers, melted unsalted butter, and sugar, mixing until crumbly. Firmly press this mixture into the bottom and up the sides of a 9.5″ tart pan. Bake for 10 minutes until set, then remove and let it cool on a wire rack. The crust should feel firm and slightly crispy to the touch.
Step 2: Make the Peppermint Mousse
In a small bowl, bloom the unflavored gelatin in cold water for about 5 minutes. Microwave it just until the gelatin dissolves fully, avoiding boiling. Melt the white chocolate chips in short intervals, stirring until smooth, then whisk in the heated milk until well combined. Add the gelatin and pure peppermint oil, allowing this mixture to cool to 85°F (29°C).
Step 3: Whip and Combine
In another bowl, whip the very cold heavy cream with powdered sugar until medium-stiff peaks form. This creamy delight should hold its shape but remain light. Gently fold the whipped cream into the cooled chocolate mixture, being careful not to deflate the fluffy texture. This combination forms the airy peppermint mousse for your Dark Chocolate Peppermint Mousse Tart.
Step 4: Assemble and Chill
Spoon the mousse mixture into your cooled chocolate crust, smoothing the top with a spatula for an even surface. Cover the tart with plastic wrap and refrigerate it for at least 2 hours, or better yet, overnight. The mousse will firm up beautifully, providing an elegant texture that complements the rich crust.
Step 5: Prepare the Dark Chocolate Glaze
In a small saucepan, bring the cream to a boil, then remove from heat. Stir in the bittersweet or dark chocolate until completely melted and smooth. Mix in the light corn syrup and very warm water, whisking until the glaze is glossy and well combined. This velvety glaze will be the shimmering finish on your Dark Chocolate Peppermint Mousse Tart.
Step 6: Glaze and Set
Once the mousse is set, gently pour the warm chocolate glaze over the tart, ensuring it evenly covers the top. Use a spatula to spread it if necessary. Allow the glaze to set at room temperature for about 1 hour. This step is crucial for achieving that iconic shine, giving your tart a beautiful presentation before serving.
Step 7: Serve with Style
The Dark Chocolate Peppermint Mousse Tart is best enjoyed the same day but can be stored in the refrigerator for 3-4 days. When ready to serve, slice with a hot knife for clean edges. Consider garnishing with whipped cream or crushed peppermint for an extra festive touch that highlights the delightful layers of this holiday dessert.
How to Store and Freeze Dark Chocolate Peppermint Mousse Tart
Fridge: Store the tart covered in the refrigerator for up to 3-4 days. This keeps the mousse fresh and maintains its delightful texture.
Freezer: If you need to freeze the tart, wrap it tightly in plastic wrap followed by aluminum foil. It can be stored in the freezer for up to 2 months.
Thawing: To enjoy your frozen Dark Chocolate Peppermint Mousse Tart, transfer it to the fridge for several hours or overnight to thaw, allowing it to come back to its perfect texture.
Reheating: There’s no need to reheat this dessert; simply serve it chilled for the best experience!
Make Ahead Options
This Dark Chocolate Peppermint Mousse Tart is perfect for busy holiday cooks looking to save time! You can prepare the chocolate crust and the mousse up to 24 hours in advance; simply store the cooled crust wrapped tightly in plastic wrap, and refrigerate the mousse in an airtight container. When you’re ready to complete the dessert, spoon the mousse into the crust and refrigerate it until set for at least 2 hours or overnight. The dark chocolate glaze can also be prepared ahead and stored separately; pour it over the mousse just before serving for that fresh, glossy finish. By prepping in advance, you’ll enjoy a stunning dessert without the last-minute rush!

Dark Chocolate Peppermint Mousse Tart Recipe FAQs
How do I choose ripe ingredients for the mousse?
Absolutely! When selecting your chocolate, opt for high-quality bittersweet or dark chocolate with at least 70% cacao for a rich flavor. For the cream, ensure it’s fresh and preferably very cold before whipping to achieve the perfect airy texture in the mousse. It’s essential that the peppermint oil is pure for the best flavor infusion—watch out for any dark spots or off-odors, as these may indicate spoilage.
What are the best storage methods and duration for leftovers?
Very! After preparing your Dark Chocolate Peppermint Mousse Tart, store it covered in the refrigerator for up to 3-4 days. This will keep the mousse fresh and maintain its delightful texture, so it’s still a treat when you indulge later!
Can I freeze this mousse tart?

When you’re ready to enjoy, simply transfer it to the refrigerator for several hours or overnight to thaw gently, ensuring that the mousse texture remains intact.
What should I do if my mousse doesn’t set properly?
If your mousse isn’t setting, it might be due to the gelatin not being activated correctly. Make sure to bloom the gelatin in cold water for the recommended time and thoroughly dissolve it without boiling. If you find the texture too runny, you could try refolding in some more whipped cream or chilling it a bit longer to see if that helps!
Is this dessert safe for people with dietary restrictions?
Very! It’s important to note that this recipe isn’t gluten-free due to the chocolate graham crackers. However, you can use an Oreo cookie crust to make it gluten-free or swap out the gelatin for agar-agar for a vegetarian option. Always check the labels of your ingredients for allergens, especially in the case of the white chocolate, and consider using a non-dairy alternative for a vegan version!
How should I serve this dessert elegantly?
