Storage: Wrap tightly and store at room temperature for 3-4 days, refrigerated for up to a week, or freeze for up to 3 months. Reheat slices for 15 seconds in microwave or 5 minutes in toaster oven at 325°F.
Key Tips: Don't squeeze zucchini bone-dry – it needs moisture to hydrate the cake mix. Overmixing develops gluten and makes the bread tough. Use a standard 15.25 oz box of cake mix for best results.
Variations: Gluten-free: use GF yellow cake mix + 1 tbsp GF flour. Dairy-free: use dairy-free cake mix and chips. Spice version: replace yellow with spice cake mix, omit cinnamon, add raisins and pecans.
