Method
Prep
- Preheat the oven to 350°F and grease a 9x5 loaf pan so the batter slides out cleanly.
- Whisk all-purpose flour, unsweetened cocoa powder, baking soda, and salt together in a bowl until the color is even.
Mix batter
- Beat granulated sugar, eggs, vegetable oil, Greek yogurt (full fat), vanilla extract, and strong brewed coffee (if using) until smooth.
- Stir in the grated, squeezed-dry zucchini until evenly distributed.
- Fold the dry ingredients into the wet ingredients until just combined to keep the crumb tender.
- Fold in chocolate chips so they’re suspended throughout the batter.
Bake and cool
- Pour the batter into the prepared loaf pan and bake at 350°F for 55–65 minutes, until a toothpick comes out with moist crumbs.
- Cool the loaf for 15 minutes before slicing so the center sets without crumbling.
Notes
For the moistest texture, squeeze the grated zucchini very dry—excess moisture can make the loaf dense. Store covered at room temperature for up to 3 days or refrigerate up to 5 days; freeze slices for up to 2 months. If you want a lighter option, swap to low-fat Greek yogurt (the tang stays, but the crumb may be slightly less rich).
