Method
Preheat and prep pans
- Preheat the oven to 350°F and grease two 9x5 loaf pans (or prepare one large pan). Grease thoroughly so the domed loaf releases cleanly after baking.
Mix dry ingredients
- Whisk all-purpose flour, baking soda, baking powder, salt, cinnamon, and nutmeg together. Keep whisking until the spices are evenly distributed with no visible clumps.
Mix wet ingredients
- Whisk granulated sugar, eggs, vegetable oil, and vanilla extract until well combined. The mixture should look glossy and smooth before you add zucchini.
Fold in zucchini and optional walnuts
- Stir in the grated zucchini (no squeezing). The batter will look slightly thick but should stay moist because the zucchini releases moisture as it bakes.
Combine and finish batter
- Add the dry ingredients and stir until just combined, folding in walnuts if using. Stop as soon as no dry streaks remain to avoid a tough loaf.
Bake
- Divide the batter between the prepared pans, sprinkle turbinado sugar on top, and bake 55–65 minutes at 350°F. Bake until a toothpick inserted in the center comes out clean and the crust turns deep golden-brown.
Cool before slicing
- Cool the loaves for 20 minutes before removing from the pans. Letting them set helps the split dome hold its shape when you slice.
Notes
Pro tip: Use unsqueezed, finely grated zucchini so the loaf stays moist and develops that classic domed, split top. Store airtight at room temperature up to 3 days or refrigerate up to 5 days; freeze slices up to 2 months. For a nut-free version, omit the walnuts—no other changes needed.
