Notes

  1. Stand-Up Mixer: If creaming sugar and butter, I typically use the stand mixer. My arm gets tired with a handheld, and the stand mixer does the work for you.
  2. Variations: Add raisins (1/2 cup) if desired. Omit the shredded coconut and/or nuts and just top with the glaze. But don’t skip the last step. Getting the glaze hot and bubbly is a big part of this cake’s charm!
