  • 1/2 cup unsweetened cocoa powder (Dutch-processed or natural)

  • 1/4 cup melted butter or coconut oil

  5. Pour batter into the prepared cake pan and smooth the top.
  6. Bake for 22–26 minutes or until a toothpick comes out with a few moist crumbs.
  7. Let cake cool in the pan for 30 minutes before removing.
  8. While cooling, heat 3/4 cup heavy cream or coconut cream until just steaming.
  9. Pour over 6 oz chopped sugar-free dark chocolate and let sit 1–2 minutes.
  10. Stir ganache gently until smooth, let cool slightly, then pour over cooled cake for a glossy finish.
