Step‑by‑Step Instructions for Dark Chocolate Peppermint Mousse Tart
Step 1: Make the Crust
Preheat your oven to 350°F (175°C). In a mixing bowl, combine crushed chocolate graham crackers, melted butter, and sugar until well-blended. Press this mixture firmly into the bottom and up the sides of a tart pan. Bake for 10 minutes or until slightly set and fragrant. Remove from the oven and let the crust cool completely on a wire rack.
Step 2: Prepare Mousse
While the crust cools, bloom the unflavored gelatin in a small bowl with cold water for about 5 minutes. After blooming, gentle heat in the microwave until fully dissolved. In a saucepan, melt the white chocolate chips over low heat and mix in the heated milk using a whisk. Once combined, fold in the dissolved gelatin and peppermint oil. Allow this mixture to cool to approximately 85°F (29°C).
Step 3: Whip Cream
In a separate mixing bowl, beat the heavy whipping cream and powdered sugar until medium-stiff peaks form. This should take about 3-5 minutes on high speed. Carefully fold one-third of the whipped cream into the cooled chocolate mixture to lighten it, then gently fold in the remaining whipped cream until fully combined. This incorporation creates the light, airy texture essential for the Dark Chocolate Peppermint Mousse Tart.
Step 4: Assemble and Chill
Spoon the prepared peppermint mousse into the cooled chocolate graham cracker crust, spreading it evenly to the edges. Smooth the top for an elegant finish. Cover with plastic wrap and refrigerate overnight, allowing the mousse to set and flavors to meld beautifully, creating a sublime texture.
Step 5: Finish with Glaze
On the day of serving, prepare the glaze by heating heavy cream in a saucepan until it reaches a boil. Remove from heat and stir in the bittersweet chocolate until melted and smooth. Then, mix in light corn syrup and a little warm water to achieve a glossy consistency. Pour the glaze over the chilled mousse, tilting the tart to cover the surface evenly.
Step 6: Set and Serve
Let the Dark Chocolate Peppermint Mousse Tart sit at room temperature for at least 1 hour after glazing to allow the glaze to set perfectly. Before serving, you might want to garnish with crushed candy canes for a festive touch. Slice and enjoy this indulgent, refreshing treat that’s perfect for any celebration!

The Dark Chocolate Peppermint Mousse Tart is a fantastic choice for those busy weeks when meal prepping is essential! You can prepare the chocolate graham cracker crust up to 3 days in advance; just ensure it’s completely cooled and store it in an airtight container at room temperature to maintain its crispness. The mousse can be made 24 hours ahead; follow the instructions up to chilling it in the crust, then simply cover it tightly with plastic wrap in the fridge. On the day of serving, whip up the glaze and pour it over the chilled mousse before slicing. This way, you’ll have a delectable, festive dessert ready to impress your guests with ease!

Dark Chocolate Peppermint Mousse Tart Recipe FAQs
How do I choose the right chocolate graham crackers?
When selecting chocolate graham crackers, look for a brand that has a rich chocolate flavor and a texture that isn’t too crumbly. This will ensure your crust is sturdy enough to hold the mousse. If you’re in a pinch, an Oreo crust makes a delightful substitute, offering a similar sweetness and crunch!
What is the best way to store leftover mousse tart?
To keep your Dark Chocolate Peppermint Mousse Tart fresh, store it in the refrigerator for up to 3-4 days. Ensure you cover it with plastic wrap to prevent the mousse from picking up any odors from the fridge. It’s best enjoyed chilled; let it sit at room temperature for a few minutes before serving to avoid condensation on the glaze.
Can I freeze my mousse tart?
Absolutely! You can freeze your Dark Chocolate Peppermint Mousse Tart for up to 1 month. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. When you’re ready to indulge, transfer it to the fridge overnight to thaw gently. Allow a few minutes at room temperature before slicing to ensure the perfect texture.
What if my mousse doesn’t set properly?
If your mousse doesn’t set as expected, there could be a couple of reasons. First, ensure you bloomed the gelatin correctly; it needs to absorb cold water initially before being heated. If the mousse mixture was too warm when adding the gelatin, it may not hold. In the future, you can refrigerate the tart for an additional hour or so to help it set properly!
Is this mousse tart suitable for those with allergies?
The Dark Chocolate Peppermint Mousse Tart contains common allergens like dairy and gelatin. For a vegan option, substitute the unflavored gelatin with agar agar and use coconut or almond milk instead of dairy. Always check labels for cross-contamination if allergies are a concern.
How can I enhance the festive flavors of the mousse?
You can experiment with different variations to customize your tart! Consider adding a sprinkle of crushed candy canes on top for a festive garnish, or incorporate citrus zest, such as orange or lemon, into the mousse for a refreshing twist that balances the richness of chocolate.
