Ingredients
To create this luscious Dark Chocolate Peppermint Mousse Tart, you’ll need the following ingredients:
For the Crust
- 1 cup chocolate graham crackers, finely ground (I used about ten 5 x 2 1/4 graham crackers)
- 6 tablespoons melted butter
- 1/4 cup sugar
For the White Chocolate-Peppermint Mousse
- 1 teaspoon unflavored vegan gelatin
- 2 tablespoons cold water
- 4 ounces white chocolate chips
- 2 1/2 tablespoons milk, half and half or cream
- 1 tablespoon powdered sugar
- 1 cup heavy whipping cream
- 3-4 drops pure peppermint oil
For the Dark Chocolate Glaze
- 1/4 cup heavy whipping cream
- 3 1/2 ounces bittersweet or dark chocolate (I used a good quality, 70% cocoa chocolate)
- 2 teaspoons light corn syrup
- 2 tablespoons very warm water
How to Make Dark Chocolate Peppermint Mousse Tart
Step 1: Preheat the Oven
Preheat your oven to 350 degrees F. This ensures that your crust will bake evenly.
Step 2: Prepare the Crust
- Combine the ground graham crackers, melted butter, and sugar in a mixing bowl.
- Press this mixture evenly into the bottom and sides of a 9.5-inch tart pan.
- Bake for 10 minutes, then cool on a rack for at least 15 minutes.
Step 3: Bloom the Gelatin
Sprinkle the vegan gelatin over cold water in a small bowl and allow it to bloom for about 5 minutes. Then microwave it for 15-30 seconds until just dissolved; do not boil!
Step 4: Melt White Chocolate
Melt the white chocolate in a microwave-safe bowl using 30-second intervals, stirring in between until smooth. Heat the milk until just steaming (about 30 seconds), then whisk it into the melted white chocolate along with the bloomed gelatin and peppermint oil until fully combined.
Step 5: Whip Cream
In another bowl, whip the heavy cream with powdered sugar until medium-stiff peaks form. Fold one-third of this whipped cream into the chocolate mixture gently, then fold in the remaining whipped cream until no streaks remain.
Step 6: Fill Tart Shell
Spoon this light mousse into your cooled tart shell. Smooth out the top with an offset spatula, then let it set in the fridge for at least a few hours or overnight if possible.
Step 7: Prepare Glaze
Once chilled, prepare your glaze by bringing heavy cream to a boil before removing it from heat. Stir in chopped dark chocolate until smooth, followed by corn syrup and warm water until fully combined.
Step 8: Glaze Tart
Pour this glossy glaze over your chilled mousse-filled tart. Tilt and rotate to coat evenly; ensure no white shows through. Let stand until set (about one hour).
Step 9: Serve
This Dark Chocolate Peppermint Mousse Tart is best enjoyed on the day it’s made but can be stored in the fridge for up to four days. Allow it to sit at room temperature briefly before serving to avoid condensation on its beautiful glaze.

How to Perfect Dark Chocolate Peppermint Mousse Tart
Creating the perfect Dark Chocolate Peppermint Mousse Tart requires attention to detail and some helpful tips. Here are some suggestions to ensure success.
-
Use Quality Ingredients: High-quality chocolate and fresh cream make all the difference in flavor.
-
Bloom Gelatin Properly: Allowing the vegan gelatin to bloom ensures it integrates smoothly into your mixture without lumps.
-
Don’t Overwhip Cream: Whipping cream to medium-stiff peaks gives structure without being overly stiff, ensuring a light mousse.
-
Cool Gradually: Let your white chocolate mixture cool to 85 degrees before combining with whipped cream; this helps maintain texture.
-
Allow Sufficient Chilling Time: Ensure you let the tart chill long enough for flavors to meld and the texture to set properly.
-
Glaze While Warm: Pouring glaze onto the tart while it’s still warm achieves an even coating and glossy finish.

Common Mistakes to Avoid
Making the Dark Chocolate Peppermint Mousse Tart can be an enjoyable experience, but there are common pitfalls to watch for.
-
Ignoring Ingredient Temperatures: Using ingredients that are too cold or too warm can affect the texture of your mousse. Ensure your cream and eggs (if used) are at room temperature for best results.
-
Overmixing the Mousse: Overmixing can lead to a dense texture. Gently fold in the whipped cream until just combined to maintain that light and airy mousse consistency.
-
Skipping the Cooling Process: Allowing the tart crust and mousse to cool properly is crucial. Skipping this step can result in a runny mousse that doesn’t set well.
-
Not Blooming the Vegan Gelatin Correctly: If you don’t allow the gelatin to bloom, it may not dissolve properly, leading to a lumpy mousse. Always sprinkle it over cold water first and let it sit before heating.
-
Rushing the Glaze Setting Time: Patience is key! Letting the glaze set properly ensures a smooth finish on your tart. Rushing this step might cause it to be runny or uneven.
