Ingredients

Mousse

  • 3 cups chocolate chips
  • 2 cups chilled heavy whipping cream (35%), divided
  • 4 large egg yolks
  • 8 large egg whites at room temperature
  • 1 cup sweetened shredded coconut (plus 1/4 cup extra for garnish)

Caramel Sauce

  • 1 1/4 cup white sugar
  • 1/4 cup water
  • 1 cup whipping cream (35%)
  • 1/2 cup (1 stick) unsalted butter, cut into 8 pieces
  • 1 teaspoon vanilla extract

Instructions

  • MAKE CHOCOLATE MIXTURE: Melt chocolate chips in a medium or small saucepan over low heat, stirring until smooth. Stir in 1 cup cream and 1 cup (85 grams) grated coconut. Pour into a large bowl and let cool to room temperature. Whisk egg yolks into cooled chocolate mixture.
  • WHIP CREAM: Using an electric hand mixer or immersion blender, in a separate bowl, beat the chilled whipping cream until soft peaks form. Set aside (place bowl in fridge if possible).
  • BEAT EGG WHITES: Clean and dry the beaters, then in a separate small bowl, beat egg whites until stiff peaks form, but not dry.
  • COMPLETE THE MOUSSE AND FREEZE: Gently fold whipped cream into the melted chocolate mixture in 2-3 stages. Then gently fold in whipped whites. Pour mousse mixture into a 10 inch (25 cm) springform pan (9 inch/23 cm will work too) with 2 inch/5 cm sides. Cover with plastic wrap and freeze at least 6 hours or overnight. 
  • MAKE CARAMEL SAUCE: Stir sugar and water over low heat in a medium saucepan until it dissolves (about 5-7 minutes). Increase heat to medium heat and gently boil WITHOUT STIRRING until the syrup turns a deep amber color (about 8-9 minutes). Carefully add whipping cream (it will bubble vigorously) and stir until smooth. Remove from heat. Stir in butter and vanilla until smooth. If making a day ahead (or more), cover and refrigerate, then when ready to use, heat on low, stirring frequently until warm. Put sauce in a gravy or coffee thermos if desired to keep warm.
  • TO SERVE: Place mousse in fridge for 30 minutes before serving to soften slightly. Run a sharp knife around the sides, the release the sides of the spring form pan. Place mousse (with bottom of spring form pan) on a serving plate. Sprinkle on coconut for garnish (I like to toast coconut first). Ladle a bit of warm caramel sauce onto plates. Slice mousse into thin wedges (it's very rich so keep slices thin!). Drizzle on a bit more sauce you like. Dig in!

Notes

  1. Expert tips on how to make mousse (by Food52)
    • Follow the instructions in the order given in the recipe.
    • Make sure the 'base" - in this recipe, the chocolate - comes to room temperature before adding other ingredients.
    • Lightly fold in the 'aerators' one at a time - in this recipe, whipped cream and whipped egg whites. Work quickly and lightly. Use a rubber spatula and don't over mix in order to keep the mousse light. Add the aerators a bit at a time (in 3 parts).
    • The mousse must be refrigerated to set. For this recipe, the mousse sets in the freezer.
    • Have all your ingredients prepped and ready to go. You will need lots of separate bowls. 
  2. Variations to try with the mousse pie:
    • Leave out the coconut if you or your guests don't like coconut.
    • Instead of warm caramel sauce, you can try a pureed berry sauce.
    • If you like a salted caramel sauce, just add a pinch of sea salt to the sauce or sprinkle on a few bits of flaky salt when serving.
  3. Make Ahead: The mousse and caramel sauce can be made 2 days ahead. (I've kept leftovers in the freezer and the caramel sauce in the fridge tightly covered for over a week and they were still sinfully good).
