How to Make Dark Chocolate Peppermint Mousse Tart

Prepare Chocolate Crust: Preheat your oven to 350°F (175°C). Combine the ground chocolate graham crackers, melted butter, and sugar in a bowl. Press the mixture firmly into a 9.5″ tart pan. Bake for 10 minutes, then let it cool on the rack for 15 minutes.
Make Peppermint Mousse: Bloom the gelatin in cold water for 5 minutes. Gently dissolve it in the microwave (avoid boiling). Melt the white chocolate and mix it with heated milk, gelatin, and peppermint oil until smooth. Let it cool below 85°F. In another bowl, whip the heavy cream with powdered sugar to medium-stiff peaks, then gently fold this into the chocolate mixture.
Assemble Mousse Tart: Pour the mousse into the cooled crust, smoothing the top with a spatula. Refrigerate for at least 4 hours or overnight until the mousse is set.
Prepare Dark Chocolate Glaze: Once the mousse has set, bring the cream to a boil and mix in the chopped bittersweet or dark chocolate until you achieve a smooth consistency. Stir in corn syrup and warm water until combined.
Glaze Tart: Carefully pour the glaze over the mousse tart, tilting to ensure even coverage. Allow it to set at room temperature for about 1 hour.
Serve: This delightful tart is best enjoyed the same day it’s made, but can be stored covered in the refrigerator for 3-4 days.

Optional: Garnish with crushed peppermint candies or chocolate shavings for extra flair.

Make Ahead Options

These Dark Chocolate Peppermint Mousse Tarts are ideal for meal prep enthusiasts, allowing you to savor the holiday spirit without last-minute stress. You can prepare the chocolate crust up to 24 hours in advance; simply bake, cool, and store it wrapped at room temperature. The peppermint mousse can be made ahead as well, and stored in the refrigerator for up to 3 days before assembling. To maintain the quality, ensure that the mousse is covered tightly to prevent drying or absorption of odors. When you’re ready to serve, pour the glaze over the mousse tart and allow it to set for 1 hour at room temperature, ensuring that your dessert remains just as delicious and festive for your gathering!

Dark Chocolate Peppermint Mousse Tart Recipe FAQs

How do I select ripe ingredients for my Dark Chocolate Peppermint Mousse Tart?
Absolutely! For the best results, use high-quality bittersweet or dark chocolate (70% cocoa recommended) as its rich flavor truly elevates the tart. Ensure your heavy whipping cream is fresh, as it adds airiness to the mousse. For peppermint oil, opt for pure extract, which provides a vibrant minty taste that perfectly complements the chocolate.

How should I store my Dark Chocolate Peppermint Mousse Tart?
Very easy! Keep the tart covered in the refrigerator to retain its freshness for up to 3-4 days. This helps maintain the texture of the mousse and the shine of the glaze. If serving later, let it sit at room temperature for a short while before cutting to prevent any condensation from forming on the glaze.

Can I freeze the Dark Chocolate Peppermint Mousse Tart?
Yes, you can! To freeze the tart, first let it fully set in the refrigerator. Once set, you can cut it into individual slices, wrapping each tightly in plastic wrap, then in aluminum foil. This way, it’ll stay good for up to 1 month. When you’re ready to enjoy, simply thaw the slices overnight in the fridge, and let sit at room temperature for a short time before serving.

What should I do if my mousse doesn’t set properly?
If your mousse doesn’t set, it may be due to the gelatin not blooming or dissolving correctly. Make sure to bloom the gelatin in cold water for at least 5 minutes and gently heat it to dissolve, avoiding boiling. You can try adding more gelatin if it’s failed to set; simply dissolve a new batch, allow it to cool slightly, and gently fold it into the mousse to help stabilize it.

Are there any dietary considerations for the Dark Chocolate Peppermint Mousse Tart?
Yes! For a gluten-free option, substitute the chocolate graham crackers with a gluten-free crust or crushed gluten-free Oreos. Always check the labels on your chocolate and peppermint oil for any potential allergens. This dessert contains dairy and eggs, so be mindful of allergies if serving to guests.
