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 (use more if using extract, 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 degrees 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″ wide by 1″ high tart pan. Bake the crust for 10 minutes, then remove and cool on a rack for at least 15 minutes before filling.
  2. Bloom the Gelatin: Sprinkle the unflavored gelatin over the cold water and let it sit for 5 minutes to bloom. After blooming, microwave the mixture for 15 to 30 seconds until the gelatin is just dissolved; do not boil it.
  3. Melt the White Chocolate: Melt the white chocolate chips in the microwave in 30-second intervals, stirring between until fully melted and smooth.
  4. Prepare the Chocolate Mixture: Heat the milk (or half and half or cream) in the microwave until just steaming, about 30 seconds. Whisk the hot milk into the melted white chocolate vigorously until smooth. Add the dissolved gelatin and peppermint oil, whisking again until fully incorporated. Allow the mixture to cool to 85°F or lower, but do not let it solidify.
  5. Whip the Cream: In a separate bowl, whip the heavy cream and powdered sugar until medium-stiff peaks form. Fold one-third of the whipped cream into the chocolate mixture to lighten it, then gently fold in the remaining whipped cream until combined, taking care not to deflate the mousse.
  6. Set the Mousse: Pour the mousse into the cooled chocolate crust. Smooth the top with an offset spatula. Refrigerate for several hours or cover and chill overnight to allow the mousse to set properly.
  7. Make the Dark Chocolate Glaze: Once the mousse has set and is thoroughly chilled, prepare the glaze. Bring the 1/4 cup of heavy cream to a boil, remove from heat immediately, and stir in the bittersweet or dark chocolate until smooth. Stir in the light corn syrup followed by the warm water, ensuring the glaze is smooth and fully combined.
  8. Glaze the Tart: Pour the glaze over the mousse tart, tilting and rotating the tart so that the glaze coats the top evenly without any white spots showing. Let the glaze set at room temperature for about 1 hour.
  9. Serve and Store: This tart is best enjoyed the day it is finished but can be kept covered in the refrigerator for 3-4 days. Before serving, allow the tart to sit at room temperature for a few minutes to reduce condensation on the glaze.

Notes

  • Use pure peppermint oil if possible for a cleaner, fresher flavor; if using extract, adjust quantity to taste.
  • Do not boil gelatin or white chocolate mixtures to avoid grainy texture.
  • Ensure the chocolate mixture is cooled before folding in whipped cream to prevent melting.
  • The tart pan size (9.5″ x 1″) is important to get the right crust thickness and mousse volume.
  • Letting the tart sit at room temperature before slicing prevents glaze condensation.
