  4. Slowly add dry ingredients to wet ingredients, mixing just until combined.
  5. Carefully stir in boiling water; batter will be thin.
  6. Pour batter into prepared pan and bake for 25-30 minutes or until a toothpick inserted comes out clean.
  7. Cool cake completely in pan on a wire rack.
  8. Melt dark chocolate over double boiler or in microwave in short bursts; let cool slightly.
  9. Whip ¾ cup heavy cream with 2 tablespoons sugar until soft peaks form.
  10. Gently fold whipped cream into melted dark chocolate until smooth and airy.
  11. Repeat melting and whipping process for milk chocolate with ¾ cup heavy cream and 1 tablespoon sugar.
  12. Repeat melting and whipping process for white chocolate with ¾ cup heavy cream and 1 tablespoon powdered sugar.

  14. Layer milk chocolate mousse on top and chill for another 20 minutes.
  15. Add white chocolate mousse layer and chill for at least 4 hours or overnight.
  16. Before serving, garnish with chocolate shavings, fresh berries, or mint leaves if desired.
  17. Carefully remove springform ring and slice with a sharp knife warmed in hot water for clean cuts.

Notes

Use gentle folding to keep mousse light and fluffy. Chill each mousse layer sufficiently to prevent blending. Warm knife blade in hot water for clean slicing. For gluten-free, substitute flour with gluten-free blend. For dairy-free, use coconut cream and dairy-free chocolate.
