Airy, rich chocolate mousse with a velvety, melt-in-your-mouth texture is an elegant family dessert. This classic French-inspired treat delivers intense chocolate satisfaction in a light, sophisticated form.
Melt the bittersweet chocolate gently using a double boiler over low heat, stirring until completely smooth. Remove from heat and let cool slightly.
In a medium bowl, beat the egg yolks with half the sugar (2 tbsp) until thick and pale. Stir in the melted chocolate and vanilla extract until fully combined.
In a separate, clean bowl, whip the egg whites with a pinch of salt. When they become foamy, gradually add the remaining sugar and continue whipping to glossy, stiff peaks.
In another bowl, whip the heavy cream to soft peaks, being careful not to overwhip.
Fold one-third of the whipped egg whites into the chocolate mixture to lighten, then gently fold in the remaining egg whites in two batches until just incorporated. Fold in the whipped cream gently for an airy texture.
Spoon the mousse into serving glasses, cover, and chill for at least 2 hours before serving to allow the texture to set.
