   • Baking soda
   • Salt

5. Combine Mixtures
   Add the dry mixture to the wet ingredients in batches, alternating with buttermilk. Mix until just combined.

STEP 2: Make the Mousse

1. Melt Chocolate
   In a heatproof bowl, melt:
   • Chocolate
   • Butter
   Do this over a pot of simmering water (double boiler), stirring until smooth.
   Let cool slightly.
2. Whip Egg Whites
   In a clean bowl, beat egg whites until soft peaks form.
   Gradually add sugar and beat until stiff peaks form.
3. Mix Yolks and Chocolate
   Stir egg yolks into the cooled chocolate mixture.
4. Fold in Egg Whites
   Gently fold in the whipped egg whites until no white streaks remain.
5. Whip Cream
   In a separate bowl, whip heavy cream with vanilla extract until soft peaks form.
6. Fold Cream into Chocolate Mixture
   Carefully fold the whipped cream into the chocolate base. The result should be smooth and airy.

   Spread the mousse evenly over the top of the cake.
   Smooth the surface with a spatula.

4. Decorate
   Before serving, top with whipped cream swirls and a sprinkle of chocolate shavings.

💡 Tips for Mousse Cake Success

• Separate eggs carefully—any yolk in the whites can prevent stiff peaks.
• Don’t rush the cooling and chilling steps—they’re key for mousse texture.
• Use a springform pan if you want perfect sides and easy release.
• For extra chocolate intensity, add a teaspoon of espresso powder to the cake batter.
