Description

Delight in a luxurious Dark Chocolate Peppermint Mousse Tart featuring a crisp chocolate graham cracker crust, a smooth peppermint-infused white chocolate mousse, and a glossy dark chocolate glaze. Perfect for festive occasions or a sophisticated dessert treat, this tart combines rich chocolate flavors with refreshing peppermint in a creamy, melt-in-your-mouth texture.

Ingredients

Scale

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 (if using extract, adjust quantity depending on strength)

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 the Chocolate Crust: Preheat your oven to 350°F. Combine the finely ground chocolate graham crackers, melted butter, and sugar in a bowl. Press the mixture evenly into the bottom and sides of a 9.5-inch wide by 1-inch high tart pan. Bake the crust for 10 minutes, then cool it on a wire rack for at least 15 minutes.
  2. Bloom and Dissolve Gelatin: Sprinkle the unflavored gelatin over the cold water and let it bloom for 5 minutes. Then, microwave the gelatin for 15 to 30 seconds until just dissolved, making sure it doesn’t boil.
  3. Melt White Chocolate and Combine Ingredients: Melt the white chocolate chips in the microwave in 30-second intervals, stirring in between until smooth. Heat the milk or cream until just steaming (about 30 seconds), then add it to the melted white chocolate while whisking vigorously until smooth. Incorporate the dissolved gelatin and peppermint oil into the mixture, continuing to whisk until fully combined. Allow this mixture to cool down to 85°F or less without letting it solidify.
  4. Whip Cream and Fold into Chocolate Mixture: Whip the heavy cream and powdered sugar together until medium-stiff peaks form. Add one-third of this whipped cream to the chocolate mixture and stir until just combined. Then gently fold in the remaining whipped cream to maintain the mousse’s airy texture.
  5. Assemble and Chill the Mousse: Spoon the peppermint mousse into the cooled chocolate crust, smoothing the top with an offset spatula. Refrigerate for several hours or overnight to allow the mousse to set firmly.
  6. Prepare the Dark Chocolate Glaze: Once the mousse tart is chilled, prepare the glaze by bringing the heavy cream to a boil then removing from heat. Immediately stir in the dark chocolate until smooth. Add the light corn syrup followed by the warm water, ensuring the mixture is completely combined for a glossy finish.
  7. Glaze the Tart and Set: Pour the dark chocolate glaze evenly over the mousse tart. Tilt and rotate the tart to cover the entire top, ensuring no white areas remain visible. Let the glaze set at room temperature for about 1 hour.
  8. Serve and Store: This tart is best enjoyed the day it’s finished but can be kept covered in the refrigerator for 3 to 4 days. Before serving, allow it to sit at room temperature for a few minutes to prevent condensation forming on the glaze when uncovered.

Notes

  • Use high-quality chocolate for both the crust and glaze to enhance the tart’s flavor.
  • Adjust peppermint oil quantity according to its potency; start with fewer drops and add more as desired.
  • Avoid boiling the gelatin mixture to preserve its setting properties.
  • Let the mousse mixture cool properly before folding in whipped cream to maintain texture.
  • Allow the tart to rest at room temperature briefly before removing the cover to prevent moisture buildup on glaze.
