Preparation

  • Preheat oven briefly if you're making a quick sponge base; mix 1/2 cup sugar and 1/2 cup flour until they feel suspiciously like cake promise.
  • Bloom 4 packets Knox Gelatine in 1/2 cup milk (sprinkle, wait, then warm gently — not boiling).

Mousse

  • Whisk 2 lbs sour cream with 1 1/2 cups sugar and 15 oz sweetened condensed milk until the mixture feels like a cloud you can justify.
  • Fold in 2/3 cup Cool Whip for lift.
  • Slowly mix in dissolved gelatin — steady hand, calm breathing.

Assembly

  • Pour mousse over baked and cooled base (if you skipped the base, it’s fine — we’re rebels).
  • Chill until set, ideally overnight, because patience.

Ganache

  • Heat 1 cup heavy cream until steamy, pour over 1 cup semi-sweet chocolate chips with 1 stick unsalted butter, stir until glossy and dramatic.
  • Pour over chilled mousse, spread like you mean it.

Final Chill

  • Let it sit for no less than a few hours unless you enjoy semi-cold soup-cake situations.

Notes

The cake's texture improves significantly when chilled overnight. If your ganache separates, warm gently and stir until smooth.
