Step‑by‑Step Instructions for Dark Chocolate Peppermint Mousse Tart
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a mixing bowl, combine crushed chocolate graham crackers, melted butter, and granulated sugar. Stir until the mixture resembles wet sand. Press this mixture firmly into the bottom and up the sides of a 9.5″ tart pan, ensuring an even layer. Bake for 10 minutes until set, then allow it to cool completely.
Step 2: Bloom Gelatin
In a small bowl, sprinkle unflavored gelatin over 1 tablespoon of cold water and let it sit for 5 minutes to bloom. Once bloomed, microwave the mixture for about 10 seconds until dissolved completely. Set it aside to cool slightly while you prepare the mousse.
Step 3: Make Mousse
Over a double boiler, melt the white chocolate chips until smooth, stirring frequently to avoid burning. Once melted, whisk in milk or cream, followed by the dissolved gelatin and peppermint oil. Allow the mixture to cool until it is below 85°F—this will help in achieving the ideal mousse consistency.
Step 4: Whip Cream
In a separate bowl, beat the heavy whipping cream and powdered sugar together using an electric mixer. Whip until medium-stiff peaks form, which should take about 3-4 minutes. Be careful not to overwhip; the cream should be smooth and glossy to incorporate into the mousse.
Step 5: Fill Tart Shell
Gently fold the whipped cream into the cooled chocolate mixture, being careful to maintain the airiness. Once combined, spoon the mousse filling into the cooled tart shell, smoothing the top with a spatula. Cover and refrigerate for at least 4 hours or preferably overnight, allowing the flavors of the Dark Chocolate Peppermint Mousse Tart to meld beautifully.
Step 6: Prepare Glaze
Heat the cream in a saucepan until it reaches a simmer. Remove from heat and add chopped bittersweet chocolate, stirring until smooth and glossy. Mix in corn syrup and a couple of tablespoons of very warm water to achieve a pourable consistency. Allow the glaze to cool slightly before using.
Step 7: Glaze Tart
Once the mousse is set and firm, carefully pour the chocolate glaze over the top of the tart. Gently tilt the pan to ensure an even coating over the mousse. Let the tart set at room temperature for about 1 hour before slicing, allowing the glaze to firm up slightly. Serve chilled, garnished with fresh berries or crushed candy canes if desired.

Make Ahead Options
Preparing the Dark Chocolate Peppermint Mousse Tart ahead of time is a fantastic way to streamline your holiday baking and ensure that you can enjoy more time with loved ones. You can make the crust and refrigerate it up to 3 days in advance; just make sure it’s completely cooled and covered with plastic wrap to prevent it from drying out. The mousse filling can also be prepared up to 24 hours ahead—store it in the refrigerator until you’re ready to fill the crust. When it’s time to serve, simply glaze the tart with the chocolate mixture, let it set at room temperature for about an hour, and you’ll have a stunning dessert that’s just as delicious as if made fresh that day!

Dark Chocolate Peppermint Mousse Tart Recipe FAQs
What type of chocolate graham crackers should I use?
I recommend using standard chocolate graham crackers to create the crust, as they provide the right flavor and texture. If you’re looking for a gluten-free option, gluten-free chocolate graham crackers or even an Oreo crust work wonderfully as substitutes.
How do I store leftovers of the Dark Chocolate Peppermint Mousse Tart?
Store the tart covered with plastic wrap in the refrigerator for up to 3-4 days. This will help keep the mousse moist and prevent the crust from drying out. Make sure to place it on a flat surface to avoid any mishaps!
Can I freeze the tart for later?
Absolutely! For longer storage, slice the Dark Chocolate Peppermint Mousse Tart and individually wrap each piece in plastic wrap. Place the wrapped slices in an airtight container, and they can be frozen for up to 2 months. Just remember to thaw in the refrigerator overnight before enjoying.
What if my mousse doesn’t set properly?
If you find that your mousse hasn’t set well, it could be due to the gelatin not being fully dissolved. Ensure you let the gelatin bloom for the full 5 minutes and dissolve it completely before adding it to the mixture. If the issue persists, consider adjusting the amount of gelatin for future batches.
Are there any food allergies I should be concerned about?
Indeed! The tart contains dairy, gluten, and potential allergens found in chocolate. If you want to make it suitable for those with allergies, you can easily swap out the ingredients: use almond or coconut milk for dairy-free versions, and make sure to choose gluten-free crust options. Always double-check product labels for specific allergens!
How do I know when my tart is ready to be served?
The best way to ensure your Dark Chocolate Peppermint Mousse Tart is ready is to let it set in the refrigerator for at least 4 hours, preferably overnight. It should feel firm to the touch with a smooth, glossy glaze on top. For a perfect slice, serve chilled and enjoy the delightful contrast of textures!
