Ingredients You’ll Need

Creating the perfect Dark Chocolate Peppermint Mousse Tart is surprisingly simple, thanks to a handful of carefully chosen ingredients. Each one plays a vital role, from the chocolate graham cracker crust that adds a buttery crunch to the smooth mousse and luscious glaze that tie it all together with elegance.

• Chocolate graham crackers: Finely ground to form a flavorful, sturdy base that brings a subtle cocoa hint.
• Melted butter: Helps bind the crust ingredients while adding richness and moisture.
• Sugar: Sweetens the crust without overpowering the chocolate’s depth.
• Unflavored gelatin: Provides just the right texture to the mousse, ensuring it holds its airy structure.
• Cold water: Necessary for blooming the gelatin, keeping it effective and smooth.
• White chocolate chips: Melted into the mousse for a creamy, sweet foundation that complements the peppermint.
• Milk (or half and half/cream): Adds silkiness to the mousse mixture.
• Powdered sugar: Sweetens the whipped cream and balances the tart’s flavors.
• Heavy whipping cream (two uses): Whipped into the mousse for a light texture and used in the glaze for a glossy finish.
• Pure peppermint oil: Infuses the dessert with a cool, invigorating flavor that feels holiday-special but refreshingly bright.
• Bittersweet or dark chocolate (70% cocoa recommended): Delivers an intense, bittersweet contrast in the glaze, rounding out the tart.
• Light corn syrup: Adds shine and smoothness to the chocolate glaze for that professional finish.
• Very warm water: Helps incorporate the glaze ingredients evenly.

How to Make Dark Chocolate Peppermint Mousse Tart

Step 1: Prepare the Chocolate Crust

Begin by preheating your oven to 350 degrees Fahrenheit. Combine the finely ground chocolate graham crackers with melted butter and sugar, mixing until the texture resembles wet sand. Press this mixture evenly along the bottom and sides of a 9.5-inch wide, 1-inch high tart pan. Baking it for 10 minutes sets the crust beautifully, locking in that chocolatey crunch. After baking, allow it to cool completely on a rack before moving on—this step ensures the crust keeps its shape once you add the mousse.

Step 2: Make the Peppermint Mousse

Sprinkle the unflavored gelatin over cold water and let it bloom for about five minutes, which activates its setting properties. Gently warm the gelatin in the microwave for 15 to 30 seconds until fully dissolved but avoid boiling it to preserve texture. Meanwhile, melt the white chocolate chips in short bursts in the microwave, stirring often until smooth and glossy. Heat your milk until just steaming and whisk it into the melted white chocolate for a silky base. Add the dissolved gelatin along with three to four drops of pure peppermint oil, whisking thoroughly. Let this mixture cool to 85 degrees Fahrenheit or cooler, careful not to let it solidify.

Whip the heavy cream with powdered sugar to medium-stiff peaks, creating a light, fluffy component. Fold one-third of the whipped cream into the chocolate mixture to loosen it, then delicately fold in the rest to maintain airiness. Pour the mousse evenly into the cooled crust and smooth the surface with an offset spatula. Refrigerate for several hours or overnight to allow the mousse to set perfectly.

Step 3: Prepare the Dark Chocolate Glaze

After your mousse tart has chilled and set, prepare the rich dark chocolate glaze that will crown your masterpiece. Heat the heavy cream until boiling and remove it from heat immediately. Stir in the dark chocolate until the mixture becomes smooth and shiny, then add light corn syrup and stir again. Incorporate the warm water gradually, ensuring the glaze is fully combined and silky. Slowly pour the glaze over your chilled tart, tilting the pan gently to spread it evenly and cover the mousse completely. Let the glaze set at room temperature for about an hour until it firms to a glossy finish.

How to Serve Dark Chocolate Peppermint Mousse Tart

Garnishes

To elevate this already stunning tart, consider garnishing it with a few small peppermint candy pieces or crushed candy canes around the edges. Fresh mint leaves can add a pop of color and a hint of freshness. For an elegant touch, dust a light sprinkle of cocoa powder or powdered sugar on top just before serving, enhancing both the visual appeal and flavor.

Side Dishes

The Dark Chocolate Peppermint Mousse Tart pairs beautifully with a dollop of whipped cream or a scoop of vanilla bean ice cream to mellow out the rich chocolate and invigorating peppermint notes. A warm cup of coffee or peppermint tea complements the tart perfectly, creating a cozy dessert moment that lingers delightfully.

Creative Ways to Present

If you want to impress your guests, consider serving the tart with individual slices plated alongside a drizzle of raspberry sauce or a sprinkle of toasted nuts for added texture and color contrast. You can also create mini versions of this tart in small tartlet pans to make charming individual desserts for parties or gatherings.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Dark Chocolate Peppermint Mousse Tart stored in the refrigerator, covered loosely with plastic wrap or a cake dome. This prevents the glaze from sweating and maintains the mousse’s light texture. It should remain fresh and delicious for 3 to 4 days, as long as it’s properly sealed.

Freezing

You can freeze the tart for longer storage by wrapping it in plastic wrap and then aluminum foil to avoid freezer burn. When ready to enjoy, thaw it overnight in the refrigerator. Note that the texture of the mousse may change slightly after freezing, but the flavor will still delight.

Reheating

Since this is a chilled mousse tart, reheating is not recommended. Instead, allow the tart to come to room temperature for about 15 minutes before serving if it has been refrigerated. This helps the flavors and textures to shine without melting the glaze.

FAQs

Can I use peppermint extract instead of peppermint oil?

Yes, you can substitute peppermint extract, but use it sparingly and adjust the amount to taste, as it tends to be less concentrated than peppermint oil. Start with a few drops and add more if needed to avoid overpowering the mousse.

What if I don’t have a tart pan with a removable bottom?

You can still make the tart in any pie or tart pan, though a removable bottom makes it easier to extract the tart without damaging the delicate layers. If you don’t have one, line your pan with parchment paper strips on the bottom and sides to help with removal.

Is it necessary to use gelatin in the mousse?

Gelatin helps the mousse set firmly while keeping it light and airy. Without it, the mousse may be too soft to hold its shape, especially after being glazed. If you prefer a gelatin-free version, consider using a stabilized whipped cream method but expect a softer texture.

How can I make the chocolate crust gluten-free?

To make the crust gluten-free, substitute the chocolate graham crackers with gluten-free chocolate cookies or gluten-free digestives crushed finely. Make sure your chosen cookies are sturdy enough to form a crust that holds together well.

Can I use regular cocoa powder instead of chocolate graham crackers for the crust?

Regular cocoa powder alone won’t create a crust, as it lacks structure. However, combining cocoa powder with crushed cookies, melted butter, and sugar can work. The chocolate graham cracker crust adds both flavor and texture, so try to use a crumbly cookie base for the best results.

Final Thoughts

There’s just something magical about the Dark Chocolate Peppermint Mousse Tart that makes it impossible to resist.
