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.
