Ingredients

Scale

  • ½ cup unsalted butter (room temperature)
  • 1 ½ cups granulated sugar

  • ¾ cup heavy whipping cream (cold) for ganache

  4. Alternate adding dry ingredients and milk, starting and ending with flour. Mix until just combined.
  5. Divide batter into pans and bake for 30–35 minutes. Cool completely on wire racks.
  6. Bloom gelatin in water. Heat ½ cup cream with sugar, add gelatin, pour over chocolate, let sit, and whisk smooth. Cool to room temperature.
  7. Whip remaining cream to stiff peaks and fold into cooled chocolate mixture to make mousse.
  8. Line a springform pan with parchment. Layer cake, mousse, and second cake layer. Chill for at least 4 hours.

Notes

  • Use room-temperature ingredients for the best cake texture.
  • Do not overmix the batter to avoid dense cake layers.
  • Chill mousse properly to set it firmly between layers.
  • The cake can be refrigerated for up to 3 days in an airtight container.
