  • Total Time: 4 hours 20 minutes
  • Yield: 10 servings

Ingredients

Chocolate Mousse

  • 2 Tbsp (28g) salted butter, diced into 4 pieces
  • 1 cup (6 oz) semi-sweet chocolate chips
  • 1/2 cup (3 oz) bittersweet chocolate chips (or another 1/2 cup semi-sweet for a less rich flavor)
  • 2 cups (104g) mini marshmallows
  • 1/3 cup (80ml) milk (whole or 2%)
  • 1 tsp vanilla extract
  • 1 3/4 cups (415ml) heavy whipping cream

Crust

  • 1 (6 oz) store-bought chocolate cookie crust (or Oreo pie crust)

Topping

  • 1 cup (235ml) heavy cream
  • 2 Tbsp (25g) granulated sugar
  • Chocolate shavings for garnish

Instructions

  1. Combine Ingredients: Add butter, milk, semi-sweet chocolate chips, bittersweet chocolate chips, and marshmallows to a large saucepan.
  2. Melt Mixture: Heat over low heat, stirring constantly until the chocolate and marshmallows have melted completely. This may take some time, so keep stirring to prevent burning.
  3. Cool Mixture: Remove the saucepan from heat, stir in vanilla extract, then pour the mixture into a large mixing bowl. Let it cool to about room temperature, approximately 45 to 60 minutes.
  4. Whip Cream: In a chilled bowl, whip 1 3/4 cups of heavy whipping cream until very stiff peaks form. Gently fold the whipped cream into the cooled chocolate mixture to create the mousse.
  5. Fill Crust: Pour the chocolate mousse evenly into the store-bought chocolate cookie crust. You can reserve some mousse if you prefer a thinner filling.
  6. Chill Pie: Refrigerate the pie for 3 hours until it is set.
  7. Prepare Topping: Whip the remaining 1 cup of heavy cream with 2 tablespoons of granulated sugar in a cold mixing bowl using an electric hand mixer until stiff peaks form.
  8. Top and Garnish: Spread the whipped cream topping over the chilled mousse pie, then garnish with chocolate shavings for a decorative finish.
  9. Serve: Cut into slices and serve chilled. Store any leftovers in the refrigerator.
  10. Optional Variations: For a milk chocolate flavor, use 1 cup milk chocolate chips and 1/2 cup semi-sweet chocolate chips. To make chocolate shavings, run a vegetable peeler down the sides of a bar of chocolate.

Notes

  • Use a chilled bowl to whip heavy cream for better volume and stiffness.
  • Stir constantly while melting marshmallows and chocolate to avoid burning and ensure smooth texture.
  • Allow the chocolate mixture to cool fully before folding in whipped cream to prevent melting the cream.
  • The pie needs at least 3 hours chilling time for the mousse to set properly; overnight chilling is ideal.
  • Chocolate shavings add an elegant touch and can be made easily with a vegetable peeler on a chocolate bar.
  • You can reserve part of the mousse to serve later in individual cups if you prefer a thinner pie layer.
