Ingredients

Instructions

  1. Step 1: In a small saucepan, heat 1/2 cup heavy cream over medium heat until it just begins to simmer (small bubbles around the edges), then remove from heat. Add 4 oz chopped dark chocolate and 1/4 cup unsalted butter, and let sit for 2 minutes. Stir until smooth and glossy. Pour into the bottom of 4 serving glasses, spreading evenly to cover the bottom. Refrigerate for 15 minutes until set.
  2. Step 2: In a separate bowl, beat 2 large egg whites with 1/4 tsp salt until soft peaks form. Gradually add 2 tbsp granulated sugar and beat until glossy and stiff peaks form.
  3. Step 3: Gently fold the cooled chocolate ganache (from step 1) into the egg whites until no streaks remain, then fold in 1/2 tsp vanilla extract until just combined.
  4. Step 4: Spoon the mousse mixture over the set ganache layer in the glasses, smoothing the top. Refrigerate for at least 4 hours until set.
