Ingredients

  • ½ cup (120ml) hot water
  • 4 tablespoons (30g) unsweetened cocoa powder Note 1
  • ½ teaspoon instant espresso coffee
  • 1 ½ cups (260g) semi-sweet chocolate chips Note 2
  • 2 cups (480ml) heavy cream cold
  • 2 tablespoons granulated sugar

Equipment

  • small bowl
  • heatproof bowl
  • small saucepan
  • mixing bowl with the whisk attachment

Instructions

  • In a small bowl, dissolve the cocoa powder and instant espresso powder in hot water.
  • In a double boiler, melt the chocolate chips until nice and smooth. Remove the bowl from the heat and cool slightly.
  • Stir the cocoa mixture into the melted chocolate.
  • In a mixing bowl with the whisk attachment, whip the heavy cream with the sugar until hard peaks form.
  • Add 1/3 of the whipped cream and fold until mostly combined. Then combine the mixture with the remaining whipped cream and mix well until no white streaks remain.

Notes

Note 1: Dark cocoa powder can be used for a rich, dark chocolate flavor. 
Note 2: Milk, semi-sweet, or dark chocolate chips all work great. For a sweet and mild mousse, use milk chocolate. For an intense mousse, use dark chocolate chips. 
Storing Tips:
- Chocolate mousse filling is best the day you make it, however it can be made a day in advance.
- Transfer to an airtight container, or cover the bowl with plastic wrap, and refrigerate for up to 24 hours.
- Let the filling sit on the counter to soften before you use it to fill a cake.
