Prep
- Preheat oven to 350°F and grease a 9x5 loaf pan.
- Whisk all-purpose flour, unsweetened cocoa powder, baking soda, and salt together until evenly combined.
Mix batter
- Beat granulated sugar, eggs, vegetable oil, Greek yogurt (full fat), vanilla extract, and strong brewed coffee (if using) until smooth.
- Stir in zucchini, grated and squeezed dry until the batter looks evenly speckled.
- Fold dry ingredients into wet just until no dry streaks remain, then fold in chocolate chips.
Bake
- Pour batter into the prepared loaf pan and bake 55–65 minutes at 350°F until a toothpick comes out with moist crumbs and the top springs back lightly.
Cool and slice
- Cool the loaf 15 minutes before slicing to let the crumb set while staying moist.
Notes
For best moisture, squeeze grated zucchini very dry so the loaf bakes up tender instead of gummy. Store tightly wrapped at room temperature up to 3 days or in the refrigerator up to 6 days; freeze slices up to 2 months. For a dairy swap, use full-fat plain lactose-free Greek yogurt for the same tang and moist crumb.
