Step‑by‑Step Instructions for Dark Chocolate Peppermint Mousse Tart
Step 1: Preheat and Prepare Crust
Preheat your oven to 350°F (175°C). In a large mixing bowl, combine crushed chocolate graham crackers, melted butter, and sugar until the mixture resembles wet sand. Transfer this mixture to a tart pan, pressing it evenly across the bottom and up the sides. Bake for 10 minutes until set and fragrant, then allow the crust to cool for at least 15 minutes on a wire rack.
Step 2: Bloom and Dissolve Gelatin
In a small bowl, sprinkle unflavored gelatin over ice-cold water to bloom for 5 minutes. Once bloomed, transfer the mixture to the microwave, heating in short bursts of 10-15 seconds until completely dissolved, ensuring it does not boil. Set aside and allow to cool while preparing the mousse.
Step 3: Melt Chocolate and Combine Ingredients
In another bowl, melt white chocolate chips in the microwave, stirring until smooth. In a small saucepan, heat your choice of milk, half and half, or cream until steaming but not boiling. Whisk the gelatin mixture into the warm milk, followed by adding in the melted white chocolate and peppermint oil, mixing well to combine. Set aside to cool slightly.
Step 4: Whip the Cream
In a large mixing bowl, pour the heavy whipping cream and add powdered sugar. Using an electric mixer, whip the cream on high speed until you reach medium-stiff peaks, which should take about 3-4 minutes. Be careful not to overwhip, as you want the mousse to remain light and airy.
Step 5: Fold and Combine Mousse
Gently fold the whipped cream into the chocolate mixture using a spatula. Start with a small amount to lighten the mixture and then gently add the remaining whipped cream, ensuring you maintain volume. Once fully combined, pour this light, fluffy mousse into the cooled chocolate crust, smoothing the top with a spatula.
Step 6: Chill the Mousse
Cover the tart with plastic wrap or a loose lid and refrigerate for at least 4 hours or overnight, allowing the mousse to set completely. This chilling period is crucial for the perfect consistency of the Dark Chocolate Peppermint Mousse Tart, giving it the signature texture that drapes beautifully.
Step 7: Prepare the Glaze
To make the glaze, heat heavy whipping cream in a saucepan until boiling. Remove from heat and add in chopped bittersweet or dark chocolate, stirring continuously until smooth. Mix in light corn syrup and a splash of warm water to achieve a glossy glaze that flows smoothly.
Step 8: Glaze the Tart
Once the mousse has set, carefully pour the warm chocolate glaze over the tart, allowing it to flow and cover the mousse evenly. Let the tart sit at room temperature for about an hour to allow the glaze to set properly before slicing and serving.
Step 9: Serve and Enjoy
After the glaze has set, slice the Dark Chocolate Peppermint Mousse Tart into wedges. Serve chilled, adorned with a dollop of whipped cream or chocolate shavings for a festive touch. Enjoy this luxurious dessert at your next holiday gathering or special occasion!

Expert Tips for Dark Chocolate Peppermint Mousse Tart
- Gelatin Precautions: Ensure the gelatin is fully dissolved and properly bloomed to achieve a smooth mousse. Avoid adding it to hot liquids too quickly to prevent lumps.
- Whipping Technique: When whipping cream, watch for medium-stiff peaks. Overwhipping can lead to an undesirable texture in your mousse.
- Folding Gently: Use a spatula to fold the whipped cream into the chocolate mixture carefully. Over-stirring may result in a deflated mousse.
- Glaze Consistency: If your chocolate glaze is too thick, add warm water a little at a time until the desired consistency is reached before pouring it over the tart.
- Chilling Time Matters: Let the tart chill for at least four hours or overnight to ensure the mousse sets perfectly—it’s worth the wait!
- Serving Tip: Warm your knife slightly before slicing to get clean, beautiful slices of your Dark Chocolate Peppermint Mousse Tart.
Make Ahead Options
These Dark Chocolate Peppermint Mousse Tarts are perfect for meal prep! You can prepare the chocolate graham crust up to 24 hours in advance; simply bake and cool it, then store it in an airtight container. The peppermint mousse can also be made the day before serving; just pour it into the crust and refrigerate for 4 hours or overnight to let it set properly. For the glaze, make it right before serving to maintain its glossy finish, but you can prep the ingredients in advance. When ready to serve, heat the glaze and pour it over the chilled tart for an elegant touch. This way, you’ll have a stunning dessert ready to impress with minimal last-minute effort!

Dark Chocolate Peppermint Mousse Tart Recipe FAQs
What type of chocolate should I use for the glaze?
I recommend using bittersweet or dark chocolate with at least 70% cocoa content. This will enhance the deep, complex flavor of the glaze, making it rich and satisfying. Avoid using chocolate chips, as they often contain stabilizers that can interfere with achieving a smooth consistency.
How should I store the tart once it’s made?
Store the Dark Chocolate Peppermint Mousse Tart in an airtight container in the refrigerator. It’s best consumed within 3-4 days for optimal flavor and texture. Remember to allow the tart to sit at room temperature for a few minutes before serving to prevent condensation on the glaze.
Can I freeze the Dark Chocolate Peppermint Mousse Tart?
Absolutely! To freeze, wrap the tart tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator before serving to ensure it stays fresh and retains its delightful flavor.
What if my mousse doesn’t set properly?
If your mousse is too runny, it might be due to the gelatin not being fully dissolved or bloomed. Reheat the mixture gently (in short bursts) to dissolve clumps, then let it cool before folding it into the whipped cream. If the mousse has been refrigerated for several hours and is still runny, you may need to add more gelatin next time or ensure it blooms properly.
Are there any alternatives to peppermint oil?
Yes, if peppermint isn’t your favorite, you can swap it out for other flavor extracts like pure vanilla, almond, or even orange oil for a unique twist! Just start with a small amount and adjust according to your flavor preference to keep the balance vivid and enjoyable.
Can I make this recipe gluten-free?
Absolutely! Simply use a gluten-free cookie crust instead of chocolate graham crackers—gluten-free chocolate cookies work wonderfully and provide a similar flavor profile. This small change makes the dessert inclusive for gluten-sensitive guests without compromising on taste.
