Notes

Amber’s Tips For The Best Chocolate Zucchini Cake:
  • Grease and flour your bundt pan well, including the center cone, to prevent sticking.
  • Use freshly shredded zucchini and don’t squeeze it—those juices help keep the cake moist.
  • Fold in the chocolate chips last to prevent overmixing the batter.
  • Let the cake cool completely before glazing so the glaze sets properly.
  • Test doneness in a section without chocolate chips to avoid confusing melted chocolate for raw batter.
  • If you prefer a lighter crumb, use cake flour in place of all-purpose.
  • Wrap tightly for storage or freeze slices for an easy grab-and-go chocolate treat.
  • Serve with coffee, cold milk, or a scoop of vanilla ice cream for the ultimate pairing.
