There’s something unmistakably comforting about the smooth, minty chill of a Dark Chocolate Peppermint Mousse Tart. I love how the velvety mousse feels like a gentle hug wrapped in deep, bittersweet cocoa flavors, all nestled inside a crisp chocolate crust. It’s the kind of dessert that invites you to slow down and savor each luscious bite.

If you’ve been searching for a show-stopping yet approachable dessert for holiday gatherings or cozy weekend treats, this Dark Chocolate Peppermint Mousse Tart Recipe might just become your new favorite. With its harmonious balance of rich and refreshing notes, it’s truly an indulgence without intimidation.

And here’s the best part — you don’t need to be a pastry pro to pull this off elegantly. I’ll walk you through every step with warm, practical tips so you can enjoy the process as much as the final, toasty-sweet slice.

Ingredient Lowdown

• Chocolate graham crackers: Provide a toasty, deep cocoa base. If you don’t have chocolate graham crackers, classic grahams with a bit more cocoa powder can work too.
• Melted butter: Binds the crust together and adds a buttery richness that crisps beautifully when baked.
• Sugar for crust: Balances the bittersweet notes with just a touch of sweet crunch.
• Unflavored gelatin: Gives the mousse that perfect airy yet stable structure without heaviness.
• White chocolate chips: Add creamy sweetness that marries perfectly with peppermint.
• Milk or cream: Makes the white chocolate mixture silky and smooth.
• Powdered sugar: Helps stabilize the whipped cream giving it a luscious texture.
• Heavy whipping cream: Whipped into clouds, it lifts the mousse to light, pillowy heights.
• Pure peppermint oil: Delivers that fresh burst of mint flavor—just a few drops go a long way here! If you prefer extract, taste as you go to avoid overpowering sweetness.
• Bittersweet or dark chocolate (70% cocoa): For the rich, glossy glaze that finishes the tart with elegant depth.
• Corn syrup and warm water: Keep the glaze shiny and pourable with a perfect set texture.

Set Up for Success

Before you start mixing and melting, get your mise en place all set — measure your ingredients precisely, chill your tart pan if you like a crisper crust, and preheat your oven to 350°F. Having everything ready makes the whole process smoother, especially when you’re working with melting chocolate and setting gelatin.

Step-by-Step: Dark Chocolate Peppermint Mousse Tart Recipe

1. Preheat your oven to 350°F. Combine your finely ground chocolate graham crackers, melted butter, and sugar in a bowl. I love pressing this mixture firmly into both the bottom and sides of a 9.5-inch tart pan—it helps create that sturdy, golden crust that holds the mousse perfectly.
2. Bake the crust for 10 minutes, then set it on a rack to cool for at least 15 minutes. You’ll notice a warm, toasty aroma developing—the sign of a lovely base ready to hold our creamy treasure.

   Chef’s Notes & Success Tips

   When whipping cream, use a chilled bowl and beaters for best volume. Also, folding gently but thoroughly helps keep the mousse light without overworking it, which can deflate those precious air bubbles. For melting chocolate, patience is key—short bursts and stirring avoid scorching and ensure a silky finish.

   Finally, let your tart chill long enough. I usually let mine set overnight—this deepens flavor and guarantees clean, beautiful slices.

Flavor Twists for Dark Chocolate Peppermint Mousse Tart Recipe

• Add a sprinkle of crushed candy canes or peppermint bark on top for a festive crunch.
• Swap peppermint oil for orange extract and add a little grated orange zest to bring a bright, citrusy twist.
• Stir in a teaspoon of espresso powder to the chocolate glaze for a mocha layer of flavor that deepens the cocoa notes.
• Top with a dollop of whipped cream and a dusting of cocoa powder for an elegant finish.
• For a nutty texture, sprinkle toasted chopped pistachios or hazelnuts over the glaze just before it sets.

Storage & Make-Ahead Tips

• Keep your tart covered in the refrigerator—this dessert holds beautifully for 3-4 days.
• If you want to save time on a busy day, prepare the crust and mousse up to two days in advance, then add glaze just before serving.
• To avoid condensation on the glaze, let the tart sit at room temperature for 5-10 minutes before you uncover it.
• The full tart freezes well. Wrap tightly in plastic wrap and foil, then defrost overnight in the fridge before glazing or serving.
• When reheating slices, keep it chilled or only bring to room temperature for the best texture; warm mousse loses its lightness quickly.

Dark Chocolate Peppermint Mousse Tart Recipe FAQs

• Can I use peppermint extract instead of peppermint oil?
  Yes, but peppermint oil is more concentrated. Start with fewer drops of extract and increase to taste to avoid overpowering the mousse.
• What if I don’t have a tart pan?
  You can use a 9-inch springform pan lined with parchment or a pie dish, but the crust placement and presentation might differ slightly.
• How do I know when the mousse is properly set?
  It should be firm enough to hold its shape when sliced but still soft and airy—not jiggly or runny. Overnight chilling is ideal.
• Can I make this tart vegan?
  This recipe leans heavily on dairy and gelatin for texture and flavor. To veganize, you’d need special substitutes like agar-agar and plant-based creams, but results will vary.
• Can I prepare parts of this tart ahead of time?
  Absolutely! The crust and mousse can be made a day ahead and chilled, then glazed just before serving for a fresher finish.

• Yield: 8 servings
• Category: Dessert
• Method: Baking
• Cuisine: American

Ingredients

Chocolate Crust

• 1 cup chocolate graham crackers, finely ground (about ten 5″ x 2 1/4″ graham crackers)
• 6 tablespoons melted butter
• 1/4 cup sugar

Peppermint Mousse

• 1 teaspoon unflavored 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 (adjust if using peppermint extract)

Dark Chocolate Glaze

• 1/4 cup heavy whipping cream
• 3 1/2 ounces bittersweet or dark chocolate (70% cocoa recommended)
• 2 teaspoons light corn syrup
• 2 tablespoons very warm water

Instructions

1. Prepare Chocolate Crust: Preheat the oven to 350°F. Combine finely ground chocolate graham crackers, melted butter, and sugar in a bowl until evenly mixed. Press the mixture firmly and evenly into the bottom and up the sides of a 9.5-inch wide by 1-inch high tart pan. Bake for 10 minutes, then remove and cool on a rack for at least 15 minutes.
2. Bloom Gelatin: Sprinkle gelatin over cold water and let it bloom for 5 minutes. Microwave for 15-30 seconds just until dissolved; avoid boiling to preserve gelatin strength.
3. Melt White Chocolate: Melt white chocolate chips in a microwave using 30-second intervals, stirring between each until smooth. Heat the milk until just steaming, then add it to the white chocolate, whisking vigorously to combine into a smooth mixture.
4. Add Gelatin and Peppermint: Stir the dissolved gelatin and peppermint oil into the white chocolate mixture. Whisk again until completely smooth. Allow the mixture to cool down to below 85°F but do not let it set.
5. Whip Cream: In a separate bowl, whip heavy cream with powdered sugar until medium-stiff peaks form.
6. Combine Mousse: Fold one-third of the whipped cream into the chocolate mixture to lighten it, then gently fold in the remaining whipped cream until fully combined and smooth.
7. Assemble Tart: Spoon the peppermint mousse into the cooled tart shell and smooth the top with an offset spatula. Refrigerate for several hours or overnight to set.
8. Prepare Dark Chocolate Glaze: Once tart is chilled and mousse set, bring heavy cream to a boil and immediately remove from heat. Stir in the dark chocolate until smooth. Add corn syrup and warm water, stirring to create a glossy glaze.
9. Glaze Tart: Pour the glaze over the chilled mousse tart, tilting and rotating the tart to evenly coat the top with glaze. Allow the glaze to set at room temperature for about 1 hour.
10. Serve and Store: For best flavor and appearance, serve the tart the day it’s finished. Keep refrigerated, covered, and let it sit at room temperature for a few minutes before serving to avoid condensation on the glaze. Tart will keep for 3-4 days in the fridge.

Notes

• Use high-quality white and dark chocolate for best flavor.
• Pure peppermint oil provides a stronger flavor; adjust quantity if using peppermint extract.
• Do not boil gelatin or it will lose its setting properties.
• Make sure the chocolate mixture cools to below 85°F before folding in the whipped cream to prevent melting it.
• Allow tart to come to room temperature briefly before uncovering to avoid moisture buildup on the glaze.
