Ingredients

For the Crust

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

For the Mousse Filling

  • 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 you use extract, you may need to add more)

For the Glaze

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

How to Make Dark Chocolate Peppermint Mousse Tart

Step 1: Preheat the Oven

Preheat your oven to 350 degrees F.

Step 2: Prepare the Crust

Combine the crust ingredients:
1. In a mixing bowl, combine the finely ground chocolate graham crackers, melted butter, and sugar.
2. Press this mixture evenly into the bottom and sides of a 9.5-inch tart pan.
3. Bake for 10 minutes until set. Cool on a rack for at least 15 minutes.

Step 3: Bloom the Gelatin

Sprinkle gelatin over cold water:
1. Allow it to bloom for about 5 minutes.
2. Microwave for 15-30 seconds until just dissolved; do not boil!

Step 4: Melt White Chocolate

Melt white chocolate:
1. In a microwave-safe bowl, melt white chocolate at 30-second intervals until smooth.
2. Heat milk until steaming (about 30 seconds) and whisk into melted white chocolate until combined.
3. Add bloomed gelatin and peppermint oil; whisk until smooth. Let cool to below 85 degrees but do not let it resolidify.

Step 5: Whip Cream

Whip heavy cream:
1. In another bowl, whip heavy cream with powdered sugar until medium-stiff peaks form.
2. Fold one-third of whipped cream into the cooled white chocolate mixture gently.
3. Then fold in the remaining whipped cream until fully incorporated.

Step 6: Assemble Tart

Fill tart shell:
1. Spoon mousse mixture into the cooled tart shell.
2. Smooth the top with an offset spatula and refrigerate for several hours or overnight.

Step 7: Prepare Glaze

Make your glaze:
1. Bring heavy cream to a boil in a saucepan; remove from heat immediately.
2. Stir in chopped dark chocolate until smooth.
3. Add corn syrup followed by warm water; combine completely.

Step 8: Glaze Tart

Pour glaze onto tart:
1. Carefully tilt and rotate the tart so glaze coats evenly.
2. Allow standing until set (about one hour).

Step 9: Serve

Serve chilled:
This tart tastes best on the day it’s made but can be stored covered in the fridge for up to four days.

Now you’re ready to enjoy this delightful Dark Chocolate Peppermint Mousse Tart, a treat that’s sure to become a favorite!
