Method

Base Layer

  1. 1

    Prepare the Base

    In a medium bowl, combine the graham cracker crumbs, cocoa powder, sugar, melted unsalted butter, and salt. Mix until well combined and the mixture resembles wet sand.

  2. 2

    Form the Crust

    Press the mixture into the bottom of a 9x9-inch baking dish evenly. Use the back of a measuring cup or your hands to pack it tightly. Bake in a preheated oven at 350°F (175°C) for 10 minutes.

  3. 3

    Cool the Base

    Remove the crust from the oven and allow it to cool completely in the baking dish.

Chocolate Mousse

  1. 4

    Melt the Chocolate

    In a heatproof bowl, melt the dark chocolate over a double boiler (or microwave in 20-second intervals) until smooth. Allow to cool slightly.

  2. 5

    Whip the Cream

    In a large mixing bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form. Set aside.

  3. 6

    Beat Egg Whites

    In another bowl, beat the egg whites until foamy. Gradually add granulated sugar and continue beating until stiff peaks form.

  4. 7

    Combine Mixtures

    Gently fold the melted chocolate into the whipped cream until well combined. Then, fold in the beaten egg whites until no white streaks remain. Be careful not to deflate the mixture.

  5. 8

    Pour Mousse

    Spread the mousse mixture evenly over the cooled crust in the baking dish. Smooth the top with a spatula.

  6. 9

    Chill

    Refrigerate the assembled mousse bar for at least 4 hours or until set.

Serving

  1. 10

    Garnish and Serve

    Before serving, top the mousse with whipped cream and sprinkle with chocolate shavings. Cut into bars and serve chilled.
