Notes

  • Measure flour using the spoon-and-level method to avoid a dry cake.
  • Don't skip the hot coffee — it deepens the chocolate flavor without adding a coffee taste.
  • For an extra-moist crumb, swap half the granulated sugar for light brown sugar.
  • Wrap cooled cake layers in plastic wrap to lock in moisture before frosting.
  • Store at room temperature for up to 2 days, refrigerated for up to 5 days, or freeze unfrosted layers for up to 3 months.
